I went from an 1180 on the PSAT to a 1590 on the SAT and over the past 3 years I've released hundreds of videos
to help students Ace the SAT this video is a completely free digital SAT prep course designed to help you improve as
much as possible in only about 18 hours of prep if you only have 8 hours or less to prep for the digital sat then I
recommend you check out my free 7-hour digital SAT prep course which you can find right here the first 7 and 1/2
hours of this course are actually the same as the free 7-hour course but the rest of this course adds on additional
training and practice for those with more time to prepare as a result I highly recommend this course to anyone
with the time to complete it before their sat while there are time stamps for each section I highly recommend that
you watch the entire course in the order it is presented I also want to note that while reading and writing is a combined
section on the digital sat there are still questions that primarily test your reading abilities and questions that
primarily test your writing abilities therefore at certain points in the course you will notice that I will speak
exclusively about either reading or writing questions put a lot of time effort and planning into this course and
I would greatly appreciate it if you would subscribe and like the video with that being said please enjoy the course
and let's get started with a guide on what you need to know for the writing questions on the digital sat so we have
subject verb agreement as a basic rule the subject and the verb of a sentence must agree in number singular or plural
here's an example the dog barks loudly the subject dog is singular and the verb barks is singular here's a second
example the dogs bark loudly the subject dogs is plural and the verb bark is plural now at this point you may be
wondering how do I know if a verb is singular or plural one trick that can help you is to use what I call the he
they test so as an example we would say he barks so as you can see he is singular and Barks then would be
singular if we were to say um he bark obviously that would not work because he is singular and bark is plural now we
would say they bark okay so as you can see by using he and they you can kind of figure out if a verb is singular or
plural with that being said let's take a look at question number 19 to how we can apply this so we have when writing the
other black girl 2021 novelist zakiah deila Harris Drew on her own experiences working at a publishing office the
award-winning book is Harris's first novel but her writing blank honored before okay in this case we have her
subject or our subject which is writing okay so writing is our subject writing is singular okay so since writing is
singular we need to have a singular verb that matches that so option A were well we would say they were we would not say
he were okay we would say he was and we would say they were so were is plural so we can get rid of a since it's plural
I'll mark that with a p then we have have been well we would say they have been and we would say he has been so as
you can see have been would have to also be plural so we can mark that with a p and then we have has been okay we would
say he has been so as you can see that would be singular we would say they have been okay so we can mark C as a singular
verb if we look at option D we have are we would say they are and we would say he is okay so d would be plural as well
okay so we can go and get rid of that we see our only answer Choice here that is singular is option C and we have to
match the number of our verb to the number of our subject writing is singular so our answer here has to be C
all right let's keep moving we've got indefinite pronouns okay indefinite pronouns such as everyone someone and no
one take singular verbs here's an example everyone has their own opinion the indefinite pronoun here is everyone
and it's singular the verb has is also going to have to be singular example number two no one knows the answer the
indefinite pronoun no one is singular and the verb knows is singular okay now let's talk about
compound subjects when two subjects are joined by and they usually will take a plural verb example of this would be JN
and Sarah are going to the party subjects JN and Sarah are plural so so the verb are must also be plural we
would not say John and Sarah is going to the party because is is singular we would have to use R which is plural
let's take a look at a second example apples and oranges are fruits subjects apples and oranges are plural so the
verb R must be used and keep in mind R is plural is is singular now let's talk about collective nouns collective nouns
represent a group of individuals can take either a singular or plural verb depending on the context however most
commonly collective nouns take a singular verb and I really want you to pay close attention to the fact that
most commonly collective nouns do take a singular verb now collective nouns utilize a singular verb when they act
when the entity acts as a whole in a plural verb when the individual members of The Entity act independently so let's
look at an example of this the team is practicing for the game the team collectively is practicing so the verb
is is singular now in example two the team are in disagreement on the course of action in this case the people on the
team disagree with each other so they are acting independently so the verb is plural okay if we scroll up we can see
that collective nouns will utilize a singular verb when the entity acts as a whole as in example one the team as a
whole is practicing for the game but in example two it's the individual members of The Entity that are acting
independently in order to be in disagreement okay so we would state that the team are in disagreement on the
course of faction now once again I want to stress that most commonly as an example three you will see that
collective nouns will have a singular verb so here's another one Congress is discussing the bill the collective noun
Congress is singular since they are collectively discussing the bill so the verb is must also be uh singular we
would say congress is discussing the bill not Congress are discussing the bill all right now let's talk about
intervening phrases these are words or phrases that come between the subject and the verb do not affect the agreement
okay so an example would be the cat along with its kittens sits by the window the subject here is cat it is not
kittens okay and cat is singular so the verb sits must also be used okay and sits is singular okay we would say he
sits we would say they sit okay so once again you can use that he they test as well if you're not sure if a verb is
singular or plural all right let's take a look at example two the boys as well as their friends are playing soccer
subject is boys which is plural and the verb are is also going to be used since our subject is plural we need to also
have that plural verb all right let's take look at a example question here so we got number
26 the classic children's board game Shoots and Ladders is a version of an ancient nepes game Pera SOA in both
games players encounter good or bad spaces while traveling along a path landing on one of the good spaces then
we have a verb a player to skip ahead and arrive closer to the end goal let's identify the number of our subject so we
have landing on one of the good spaces well on one of the good spaces is a prepositional phrase okay we would
ignore the prepositional phrase when identifying our subject so our subject here is landing okay Landing is going to
be singular so I'm going to mark that with an S for singular now let's identify a through D which ones are
plural and which ones are singular so we have allows well we would say he allows and we would say they allow okay so
allows is singular since we would use it with he but not they if we take a look at B we have are allowing we would state
that they are allowing and he is allowing okay so are right there we have plural next we have have allowed we
would State they have allowed we would State he has allowed so once again C would be plural as well if you look at
option D we would State he allows and we would state that they allow okay so that would be plural there okay we would say
landing on one of the good spaces allows a player to skip ahead and arrive closer to the end goal so as you can see only
option here that's singular for our verb is option A and once again we need to maintain that singularity in both our
subject and our verb they need to match okay so our answer there would have be a all right now let's talk about pronoun
usage okay we have pronoun antecedent agreement a pronoun must agree in number and gender with its antecedent an
example of this would be Sarah lost her keys the feminine pronoun her agrees with the female antecedent Sarah let's
look at example number two the boys finished their homework the plural pronoun their agrees with the plural
antecedent boys okay so pronoun usage there should be fairly simple let's take a look at a question to practice we have
question 19 public awareness campaigns about the need to reduce single-use Plastics can be successful says
researcher Kim Borg of monach University in Australia when these campaigns give C consumers a choice for example Japan
achieved a 40% reduction in plastic bag use after cashiers were instructed to ask customers whether blank wanted a bag
well let's identify our subject okay our subject here would be customers we know customers is plural okay so we scroll
down here so we've got customers which is plural if we look at our options we've got four different pronouns okay
one is singular you is singular and it is singular they is plural we have to maintain um we have to match our number
okay so we can get rid of options B C and D since they would not match in number with our subject okay our subject
is plural that or I'm sorry our noun is plural okay the noun that we're referring to with our pronoun that noun
is plural since our noun is PL plural our pronoun will also need to be plural so our answer there would have to be
answer Choice a all right let's talk about ambiguous pronouns pronouns should have clear antecedence to avoid
confusion here is an incorrect example and as we go through these examples try to pay attention to where I'm giving an
incorrect example versus where I am giving a correct example because otherwise you may end up getting
confused I will try to make it as clear as I can as I go through this so here would be an incorrect example Sarah and
Lisa went shopping and she bought a dress the pronoun she is ambiguous it's not clear whether it refers to Sarah or
Lisa okay so make sure that it's clear who you are referring back to if you are going to use a pronoun now here is a
correct example Tom saw joh and congratulated him okay this one is admittedly not the greatest example but
it still works and here's why when we say that Tom saw John okay Tom is still our subject okay he saw John okay John
is the object of the verb saw okay so Tom saw John and congratulated him okay this is clear that Tom saw John and Tom
is the one congratulating John okay the pronoun him is referring to the antecedent John okay let's look at
another example and this one's a bit more clear I gave Mary the book that she wanted okay the pronoun she refers the
antecedent Mary all right let's go ahead and move on to pronoun case pronouns have
different forms depending on their function in the sentence subjective objective and possessive so here's an
example I went to the store the subjective pronoun I acts as the subject of the sentence so got example two she
gave him the gift the objective pronoun him acts as the object of the verb
gave now let's talk about pronoun reference pronouns should refer clearly and unambiguously to their intended
antecedence here's an example the man who won the race was happy the pronoun who refers to the man who won the race
here's another example the dog that barked is mine the pronoun that refers to the dog that
barked now let's talk about modifier or placement and comparison Mis
modifiers modifiers should be placed near the words they modify to avoid ambiguity or confusion now here's an
incorrect example followed by the correct example I saw a draft with binoculars the modifier with binoculars
should be placed near I okay in this example it should be obvious that there's a mistake because you wouldn't
have a draft that is using binoculars it's the individual I the subject who is actually the one using the binoculars so
we need to move with binoculars in front of I okay so here's how we would correct that with binoculars I saw a draft let's
take a look at example number two okay so once again we'll start with the incorrect example Jon caught the ball
running quickly the modifier running quickly should be placed near Jon it's not the ball that is running quickly
because a ball cannot run it is Jon who is running quickly okay so we need running quickly to refer uh to be placed
next to John so here's how we would correct that we'd State running quickly as an introductory modifier John caught
the ball okay running quickly is being applied to John now let's talk about dangling modifiers modifiers should
clearly modify the intended subject or noun here's an incorrect example after finishing the project the snack was
devoured by John well the snack is not what has finished the project okay a snack cannot finish a project okay JN is
the one who finishes the project so the modifier after finishing the project should modify whoever finished the
project which is John not snack so here's how we could correct that after finishing the project J ate a snack in
this case we clearly have J being uh what comes after this introductory modifier of after finishing the
project all right let's go over another example riding the bike the tree came into view and once again this is an
incorrect example the modifier riding the bike should modify whoever was riding the bike not the tree since a
tree obviously cannot ride a bike so here's how we could correct that riding the bike John noticed the tree came into
view so as we can see we have our modifier modifying um who is actually riding the bike all right let's take a
look at this with a question all right so in 1453 English King Henry V 6 became unfit to rule after falling Gravely ill
as a result Parliament appointed Richard third Duke of York who had a strong claim to the English Throne to rule as
Lord protector upon recovering 2 years later okay so here we have an introductory modifier upon recovering 2
years later well we know the person who fell ill is King Henry okay so we need to have King Henry after this so if you
look at our options we have Henry as what's being modified the reign of Henry it can't be the reign of Henry because
Henry is the one who fell ill so Henry is the one who will recover two years later we have Henry's Reign okay it's
not his Reign that is being modified and it's not it was Henry who resumed his Reign okay it's not it we need to modify
Henry okay Henry needs to be what is immediately after that comma okay so our answer there would have to be a now this
is a pretty common type of question on the digital sat so make sure you understand how to work with these
introductory modifiers all right let's talk about comparative and superlative adjectives adjectives should be used
correctly when comparing two or more items so here's an example this book is taller than that one we're comparing the
height of two books now really what I'm trying to teach right here is pretty simple right if we're comparing two
things we would state that one is taller than the other now let's take a look at example two if we're stating that we're
comparing you know one to many doing a one to many comparison it's not a one to one comparison so in this case an
example two we have she is the smartest student in the class we're comparing the intelligence of students in the class so
this is a one to many comparison we're comparing the one which is she to all of the students in the class so we would
State she is the smartest student in the class all right parallel comparisons comparisons should be parallel in
structure here's an example she likes to run swim and Hike Okay so this one isn't really a comparison this one's just a
list of activities so we want to maintain parallelism we would not say she likes to run swimming and hiked
right we would want to maintain parallelisms to this so she likes to run swim and Hike example two the company is
efficient reliable and customer oriented this is a parallel list of qualities of the company now let's talk about double
comparisons avoid using two comparative forms in the same sentence so this kind of goes back to the school example so an
incorrect example would be she is more talented than any other student in the school okay now a much better way to say
this would be she is the most talented student in the school as you can see it cuts down on the wordiness and also
since we're doing a on to many comparison okay we would want to state that she is the most talented student in
the school not that she is more talented than any other student in the school okay because that just adds on wordiness
we want to be as concise as we can so our answer there would have to be she is the most talented student in the school
all right now let's talk about parallel ISM parallel structure in list items in a list should be presented in parallel a
form we've kind of talked about this already but I want to go a little bit further with it so we have as an example
he likes to read write and listen to music okay so parallel list of activities read write and listen the
chef prepared a delicious appetizer main course in dessert this is a parallel list of dishes now let's talk about
parallel structure in comparison so this is where we get into that comparisons that we didn't really touch on as much
earlier when making comparisons the elements being compared should have parallel structures here's an example
the company is as successful as it is innovative we're comparing success and Innovation which are two um two
qualities that can describe uh the company all right example two she is not only a talented singer but also a
skilled dancer okay we're comparing talent in singing and dancing now you want to pay attention to that structure
you want to maintain parallel structure so let's talk about parallel structure and clauses Clauses should maintain par
structure to enhance Clarity and coherence example once again we have parallel list of activities she likes to
swim to run and to play tennis so now we have to swim to run and to play okay now I know I'm stressing parallelism a lot
that's because it's pretty important on the digital SAT writing section I will um I will say that compared to the paper
sat it seems like parallelism has been um showing up a little bit less often on the digital SAT practice test than it
did on the paper sat um but that's just something that I've noticed um anyway let's talk about example number two he
wants to travel to explore and to experience new cultures we have a parallel list of desires all right now
let's talk about verb tenses proper use of verb tenses verb tenses indicate the time at which an action takes place it
is important to use the appropriate verb tense to convey the correct time frame all right so let's talk about the future
simple tense I will go to the party tomorrow this is future simple tense indicates a future action let's talk
about example number two they have already finished their homework this is present perfect tense it indicates an
action completed in the past with a present result now let's talk about sequencing events verb tenses help to
indicate the chronological order of events choose the appropriate verb tense to accurately represent the sequence of
actions here's an example she finished her meal and then paid the bill this is past simple tense it indicates actions
completed in the past another example he had left before I arrived this is past perfect tense it indicates an action
completed before another past action okay so the first past action that's completed is he had left okay and then
the next past action would be before I arrived okay so I arrived now let's talk about consistency in verb tenses
maintaining consistency in verb tenses throughout a sentence or paragraph helps to ensure Clarity and coherence and this
is something that is commonly tested on the SAT writing section so you do really want to pay attention to this part right
here so let's talk about an example she walks to work every day and always arrives on time this is present simple
tense it indicates a habitual action the way you might see this tested on the digital SAT writing section would be
that arrives would be an answer option and it would be left blank on the digital writing section so you would
have she walks to work every day and always blank on time and you would have to recognize that you have walks as your
verb tense in the sentence and you have to match the verb tense then of your answer Choice which would be arrives
here so that's one of the ways that you could see this tested let's give another example the team played well but they
lost the game this is past simple tense and indicates a past event so once again the way you would likely see this tested
is lost or played might be left out as a blank and then you'd have to recognize your verb that is left so in this case
let's say that loss was left out as a blank you would recognize you have played which is the past simple tense
and then you would need to select your answer choice that represents the past uh simple tense as well all right let's
talk about more complex verb tenses so we have future perfect the future perfect tense is used to express an
action that will be completed before a specific point in the future an example would be by this time next year I will
have graduated from college future perfect tense is indicating an action completed in the future before another
future event all right let's talk about the conditional tense the conditional tense
is used to express actions that are dependent on a condition or hypothetical situations an example is if it rained we
would have stayed indoors so once again this is conditional tense expresses a hypothetical situation okay in this case
the hypothetical situation is if it rained past perfect tense the past perfect tense is used to express an
action completed before another past action or a specific point in the past an example is she had already finished
the book before the movie was released once again this is past perfect tense indicates an action completed before
another past event let's talk about the conditional perfect okay conditional perfect tense is used to express
hypothetical actions that would have been completed under certain conditions an example is if they had studied harder
so that is the hypothetical um action they would have passed the exam so conditional perfect tense expresses a
hypothetical situation in the past so the condition here is if they had studied
harder then what would have happened is they would have passed the exam so once again the condition if they had studied
harder what would have happened is they would have passed the exam so there's the conditional perfect now we have the
present perfect continuous present perfect continuous tense is used to express ongoing actions that started in
the past and continue into the present an example is they have been playing tennis all morning so once again this is
present perfect continuous continuous tense indicates an ongoing action starting in the past and continuing into
the present okay so they began okay this action start started in the past they began playing tennis in the past and
it's continuing into the present they have been playing tennis all morning past perfect continuous the past perfect
continuous tense is used to express ongoing actions that started and continued in the past before another
past event an example is he had been working at the company for five years before he was promoted okay so once
again we are expressing ongoing actions that started and continued in the past before another past event okay so he had
started working at the company before this past event okay so he started and continued working at the company four or
five years before he was promoted which is the past event all right by understanding the nuances of different
verb tenses you can accurately convey the time frame sequence and continuity of events in your writing all right
let's talk about sentence structure so let's start with runon sentences and runon sentences are very commonly tested
on the digital SAT writing section so you do need to pay close attention here you want to avoid runon sentences by
properly separating independent clauses and we'll talk about how to do that later on okay so let's take a look at a
couple examples first so we have I walked to the store comma and I bought some groceries I walked to the store is
an independent clause I bought some groceries is another independent clause we can connect two independent clauses
with a comma and one of the Fanboys which are for and nor but or yet and so all right let's talk about uh or next
example she studied hard for the test but she still failed okay so she studied hard for the test it's an independent
clause and then we have a comma and one of the Fanboys in this case but and then we have she still failed which is also
an independent clause okay let's go ahead and move on to commas spes okay do not use a comma to join two
independent clauses without a coordinating conjunction or appropriate punctuation
here's an incorrect example I studied all night I passed the exam here we have a comma splice because we are trying to
connect two independent clauses with only comma and without one of the Fanboys okay so that's an incorrect
here's how we can correct that we would State I studied all night comma and I pass the exam now a second incorrect
example would be he ran fast he lost the race he ran fast as an independent clause he lost the race as an
independent clause here's how we could correct this he ran fast comma but he lost the race so let me quickly touch on
how you can kind of know when to use which coordinating conjunctions and if you hear coordinating conjunctions just
think the Fanboys okay the Fanboys are the most common examples of coordinating conjunctions okay so how would we know
to use but here instead of something like so or yet well he ran fast if he ran fast we would expect him to win the
race but he lost the race so this is a contrast what would be expected so we could use but in this case let's take a
look at fragments so you want to ensure that sentences have a subject and a verb and are not incomplete once again you
want your sentences to be complete so let's look at an incorrect example after finishing the race okay this would be a
sentence fragment it is not a complete idea it is not a complete sentence if we look at the correct version of that it
would be after finishing the race I felt tired I felt tired is an independent clause okay after finishing the race is
referring to I okay so that's a complete sense let's look at incorrect example number two running towards the Finish
Line okay we don't know who is running towards the Finish Line this isn't a complete thought if we look at how we'
correct that we would have running towards the Finish Line I felt exhilarated okay in this case we are
referring to I we are modifying I all right looking at D dependent clauses dependent clauses can't stand alone as
complete sentences and must be attached to an independent clause okay let me zoom in okay so dependent clauses can't
stand alone as complete sentences must be attached to an independent clause an example of this although it was raining
hard or although it was raining they went for a walk okay although it was raining is a dependent clause okay it
cannot stand alone as a complete sentence all right example number two when the bell rings class ends when the
bell rings is the dependent clause there okay it cannot stand on its own as a sentence now let's talk about
independent clauses independent clauses can stand alone as complete sentences an example would be I went to the store
that is a complete thought it's complete idea has a subject and a finite verb if we look at example number two the Sun
was shining brightly okay that is also a complete sentence now let's talk about sentence
logic and Clarity eliminating redundancy this is something that was very very commonly
tested on the paper writing section uh now that the SAT has moved digital I haven't been seeing it tested quite as
much but it is still something that's important to know okay you have eliminating redundancy remove
unnecessary repetition in sentences to improve Clarity and conciseness so here is an incorrect
example and there's a few of these that I'll go over so starting with I saw him with my own eyes with my own eyes is
redundant if I say I saw him the only way I can do that is with my own eyes so You' correct that by just stating I saw
him okay now here's two other examples that I think are a little bit more similar to what you could see on the SAT
writing section so one option would be I ran home to Megan Megan is my sister eliminate the redundancy of saying Megan
back to back okay so here's how we could do that we would State I ran home to Megan comma my sister okay my sister is
describing who Megan is and by doing this we're able to repeat stating Megan back to back so we can get rid of that
we can also eliminate having to use is by just using that comma here's another incorrect example the teacher explained
the concept briefly in a short manner okay briefly and in a short manner mean the same thing so we would only want to
use one of those and the most concise way to do that would be to get rid of in a short Manner and just say briefly so
as you can see in the correcting example we could State the teacher explained the concept
briefly let's talk about Clarity of pronoun reference you want to ensure that pronouns have clear and unambiguous
antecedence so we've kind of already touched on this let's just go over it again okay an incorrect example would be
after Sarah told Rachel the bad news she was very upset it's unclear if she refers to Sarah or Rachel the corrected
example would be after Sarah told Rachel the bad news Rachel was very upset okay here's two more correct examples John
gave the book to Mary and she read it the pronoun it refers to the book the pronoun she will refer back to
Mary all right another example would be the dog followed its owner wagging its tail happily obviously the dog would be
what's referring to by its logical comparison you want to make logical and meaning comparisons in sentences and
what this is really talking about is you want to make sure you're comparing like to like so as an example apples are
healthier than Donuts we're comparing food to food an example two the flight was longer than the duration of the
sunset okay in this case it's presumed that we're talking about the flight's duration we're comparing that to the
duration of the sunset okay if we look at option C or example C Sweden's obesity rate is less than that of the
United States and example three is one that I think is really important to highlight okay when we say Sweden's
obesity rate is less than that of the United States the key part I want you to pay attention to here is that we
included that of if we were to say Sweden's obesity rate is less than the United States that's not as good as if
we State Sweden's obesity rate is less than that of the United States because by adding that of okay we know that
we're referring to the obesity rate of the United States which is more clear than if we just say Sweden's obesity
rate is less than the United States all right let's talk about appropriate word choice you want to use words that
accurately convey the intended meaning in a sentence an example is the book he purchased was truly captivating the word
captivating accurately describes the engaging nature of the book now on the digital sat you'll more commonly see
word choice questions like this show up actually towards the um on the on the digital SAT practice test it's been
towards the beginning of the sections and it's also in my opinion um categorized more so in actually the
reading section because it's more so about the word in context but I did still want to touch on it here because
you do still need to understand words in context in order to be able to answer questions on the writing section now
some of you guys may be wondering at this point you know what's the difference sort of between reading and
wri writing on the digital sat since they're all sort of combined into the same section and it's really just about
the classification of the different questions so some questions can be classified more as reading questions
even though it's within the reading and writing section which is now combined section and some questions can be more
confined um to testing your writing abilities so when I'm talking about writing questions I'm talking about
questions that are specifically designed to test your writing ability when I talk about reading questions I'm talking
about reading questions that are specifically designed to test your reading comprehension your understanding
of words and context and things like that um so even though they are combined into the same sections they do there are
still questions that are more so testing writing and some that are more so testing reading but anyways here's
example number two it was an incredibly grueling Marathon the word grueling conveys the extreme difficulty and
exhaustion associated with the marathon next we have idioms indiction prepositions so let's talk about the
appropriate use of idioms you want to use idiomatic expressions correctly to convey the intended meaning an example
would be she passed away it's an idiomatic expression for she died they got along well that's an idiomatic
expression for they had a good relationship I'll talk about correct preposition choice and this is what um
you might see more commonly on the digital SAT writing section so using the correct preposition in phrases and
expressions an example would be she is afraid of spiders okay the preposition here would be afraid of so you could
have options that are um afraid in um afraid with but obviously you would state that she is afraid of spider so
when we're talking about preposition choice this is the way that um it could show up so example two is I am
interested in playing the piano okay so in this case we are looking at in okay interested in playing the piano okay so
the proposition there would be in um and then let's talk about uh proper use of prepositional phrases so something that
is just generally very useful to recognize on the digital SAT writing section is prepositional phrases I've
already kind of talked about how you need to get get rid of them when you're determining your subject um which is
helpful for matching the number of the subject to the number of your verb uh using prepositional phrases accurately
to provide additional information about the subject or object of a sentence an example this would be the cat is sitting
on the chair so on the chair is the prepositional phrase she walked through the forest through the forest would be
the prepositional phrase there now I can talk about punctuation apostrophes you want to use apostrophes to indicate
possession or contraction an example would be John's car is old we have an apostrophe for possession since the car
belongs to John next we have it's raining outside this is an apostrophe used for contraction because it's in
this case is it is we would say it is raining outside example three the children's toys were scattered all over
the room this is an apostrophe being used for plural possession children is already plural so we would add on the
apostrophe s to indicate that it's possessive of the toys example four these are the cats bows okay cats with
an S is the plural version of cat then we need to add an apostrophe onto the end of that to indicate that it is the
cats bows okay there is a possessive relationship there if you look at example number five we're going to the
park this is an apostrophe for contraction the contraction would be we are to were if you look at example six
they're my best friends this is an apostrophe for contraction they being the contraction of they are now let's
talk about semicolons and periods this is something that's obviously very important to understand uh so we have
use semicolons to separate independent clauses or or or to separate items in a series that already contain commas okay
and you are going to see kind of both of these uses on the digital SAT writing section you want to use periods at the
end of a complete sense so an example would be I went to the store with a semicolon I bought some milk and bread
okay so we have two independent clauses that we're connecting with a semicolon so semicolon separates independent
clauses example number two my best friends are John who is a lawyer Mary who is a nurse and Tom who is a teacher
in this case we have a semicolon separating items in a series that already contain commas so as you can see
we state name comma and then occupation who is a lawyer Mary comma who is a nurse Tom comma who is a teacher so in
this case within the list itself we have commas so we' actually use semicolons to separate each item in that list example
three I haven't been feeling well I think I might have the flu so we would use a semicolon to separate these two
independent clauses look at example four the museum exhibit includes paintings from go the Dutch artist Monae the
French impressionist and climp the Australian symbolist okay in this case semicolon separates items in a series
that already contain commas okay so if we scroll up example four is similar to example two example number five she
couldn't make it to the party she was caught up with work so in this case we're splitting up two independent
clauses with a period if you look at example six the weather was perfect for a walk it was mildly Sunny with a cool
breeze we're using a period to separate two independent clauses there as well all right let's give an example here
with question number 23 John Henson director of language revitalization program of the Chickasaw Nation in
Oklahoma help produce the world's first indigenous language instructional app Chickasaw blank and then we have
Chickasaw TV in 2010 and a Rosetta Stone language course in 2015 so what you'll see here is we have this list and we are
using a comma before we State the date okay so we have comma before we State the date so if we scroll down to our
answer choices we need to look for one that has a comma before we State the date so we can get rid of A and B since
they use semicolons here and here then if we look at the differences between C and D we see that the differences are
right here whether or not we use a semicolon or comma after the year now if we scroll up we see that after the year
we are using a semicolon okay we're using a semicolon to split up this list of items where comma is used with each
item okay so after 2019 we need to have that semicolon okay so our answer there would have to be
C all right let's talk about common you want to use commas to separate items in a series after introductory phrases to
set off non-essential Clauses or phrases and to separate coordinate adjectives an example is I bought apples oranges and
bananas at the store a comma separates the items in a series example two however comma they still manage to win
the game a comma after an introductory phrase is what we're using there all right colons you want to use
colons to introduce a list to separate Clauses when the second Clause explains or amplifies the first or to introduce a
quote or example so here's an example the ingredients for the recipe are flour sugar eggs and milk in this case we have
a colon introducing a list example two he had one thought in mind to succeed in this case we have a colon separating
Clauses example number three we have her dream was simple yet profound to travel the world and discover herself in the
process in this case the colon introduces a clause that elaborates and explains the dream mentioned in the
preceding clause in example three and example one are really the two best examples of what you could see for the
use of a colon on the digital SAT writing section in particular example three okay but both of them are really
the way that you would kind of see this show up on the on the digital SAT writing section so uh example three is
one that I want to talk a little bit more about so let's just go and discuss it her dream was simple yet profound to
travel the world and discover herself in the process if your second Clause is illustrating explaining or describing
what came before it that's a very common case where you're going to want to use a colon okay so I want to I want to really
focus in on that that when your second Clause explains or amplifies the first that's a situation where you're going to
want to use a colon all right let's talk about dashes so you'll use dashes to set off parenthetical elements or to
emphasize certain words or phrases example would be the car dash a bright red sports car-h caught everyone's
attention Okay in this case a bright red sports car is non- essential you could State the car caught everyone's
attention and it doesn't change the meaning of the sentence if we look at example two she was determined Against
All Odds to finish the race okay in this case we are emphasizing Against All Odds all right if we take a look at
adjectives and adverbs we want to know proper use of adjectives so you use adjectives to describe or modify nouns
an example would be she wore a beautiful dress to the party in this case the adjective beautiful is describing the
noun dress another example would be the tall building can be seen from miles away the adjective tall is describing
the noun building let's talk about proper use of adverbs so you'll use adverbs to modify verbs adjectives or
other adverbs an example would be he ran quickly to catch the bus the adverb quickly is modifying the verb ran
another example would be she spoke softly to avoid waking the baby the adverb softly is modifying the verb
spoke let's talk about word pairs so we need to know commonly confused words so use appropriate words and avoid common
mistakes in word usage so let's talk about a few examples and then I have a list that I'll kind of run through of
some commonly confused words so we have example one their dog is friendly this is the correct possessive pronoun okay
so it's t h i r when you want a possessive pronoun now in contrast if we look at example number two we have
they apostrophe re e going to the party okay they're going to the party this is a contraction of they are so you need to
understand the difference between t h e i and t e y apostrophe re e this is a contraction for they are let's look at
example one again we have accept the invitation to agree to something okay so the version of accept with an a at the
start if we look at example two we have except for him except with an E here everyone attended the meaning now except
ex CT is excluding someone let's look at our next example your advice is helpful well in this case we have the noun
advice if you look at example number two I advise with an S not a c you to listen to his instruction okay this is a verb
all right so now we have a list of word pairs that you should know which I'll quickly go over we have accept versus
except which I discussed above effect which is to influence versus effect which is a result compliment which is
something that completes versus complement which is praise for example I give a compliment to someone when I say
I like their shoes next we have elicit which is to draw out versus illicit which is forbidden by law its which is a
possessive form of it versus it apostrophe s it's which is a contraction of it is we have principal which is main
versus the principle or versus principle which is a fundamental belief or rule so example would be life principles right
fundamental beliefs about life stationary not moving stationary writing materials then used in comparisons then
at a time or at that time their T he i r possessive form of they uh there t h e re e is in that place and there th h e y
apostrophe re e which is a contraction of they are two is a preposition two which is also or excessively and then
two which is the number your which is a possessive form of you and your with an apostrophe r e which is a contraction of
you are let's talk about who which and whom we have the proper use of who versus whom you use who to refer to the
subject of a sentence and whom to refer to the object of a verb or preposition so an example is who is the man who
fixed my car well the subject of the verb fixed example two to whom should I address the letter the object of the
preposition to all right so let's talk about the he him trick this is really what I want to use to highlight the who
versus whom because it makes things a bit simpler it can help you determine
whether to use who or whom in a sentence so let's use example number one okay so if the answer to this question could be
he then we'll use who if the answer to the question could be him then we'll use whom okay so who is the man who fixed my
car well we could State he is the man who fixed my car okay so we would State who instead of whom okay so ask a
question who fixed my car the answer is he fixed my car so we would use who example number two to whom should I
address the letter well we can ask the question should I address the letter to him we wouldn't State should I address
the letter to to he we would say should I address the letter to him so because of that we would want to use whom there
okay so that's the that is the the he him test that you can use okay so once again that's the the he him test all
right using the he him trick makes it easier to decide whether to use who or whom based on the role the word plays in
the sentence proper use of which you use which to introduce nonrestrictive Clauses and that to
introduce restrictive Clauses so when you think non-restrictive versus restrictive another way to think about
that is essential versus non-essential so if we take a look at example one the car which is red belongs to John if we
were to remove which is red we would have the car belongs to John that doesn't substantially change the meaning
of the sentence okay so that's fine if you look at option two or example two the car that is red belongs to John well
this is restricted because we are restricting the car to the one that is red okay we're not just stating the car
belongs John we are stating the card that is red so presumably this is in a series of multiple cars of different
colors and we are stating it is the one that is red so this is restrictive to just the car that is red okay so that's
the difference between non-restrictive and restrictive all right let's talk about
distinguishing between these two understand the difference between Clauses that are necessary for
understanding the sentence and those that provide additional information example one the book that she borrowed
is on the Shelf okay that she borrowed is restrictive it's restricting which book it is it is the book that she
borrowed you look at example two her car which is blue is parked outside this is non-restrictive we are just adding in
more information but we're not restricting which car it is if we were to State her car that is blue as parked
outside then we would be restricting car but we're not in this case we're just providing additional information so it's
non-essential all right let's talk about transitions using transition words and phrases effectively use transitional
words and phrases to create coherence and a smooth flow between ideas and paragraphs example one first we went to
the store then we went to the park okay so first would be a transition here and then we have then so we're indicating a
sequential progression example two however some people disagree with this Viewpoint in this case we are providing
a contrast with however we want to coherently connect ideas and paragraphs ensure that ideas and paragraphs are
logically connected to maintain coherence in writing example number one the first reason for this decision is
financial okay so we're stating the first reason and then we have additionally it aligns with our
long-term goals so we are providing a second reason therefore we would use additionally because we're adding on
look at example exle two in conclusion there are several factors consider when making this decision so in conclusion
would be our transition there we want to maintain a smooth flow logical progression and writing okay and I'll go
over a bunch of transitions I want you to know uh in a bit here but for now let's keep talking organize ideas and
sentences to ensure a logical progression smooth flow of information so to begin with we analyze the data
next we identifi the trends finally we drew conclusions so in this case since we would start with to begin with and we
have next an example Le question that you could see is you would have to answer what transition should be here
you would notice that we are going in a sequence so you would want to use finally if we are at the last part of
that sequence okay we drew conclusions example two moreover it is important to consider the potential
consequences before taking action so in that case that' be something that we are adding on to all right so here's some
common SAT writing transitions along with example sentences so first off let's start by talking about
introductory so examples would be to begin with first and foremost in the first place initially so an example
would be initially we conducted a thorough analysis of the data next let's talk about addition and continuation
this is very common additionally furthermore moreover in addition two also moreover so an example would be
furthermore the results of the study support our hypothesis let's talk about contrast
another very common one we have however on the other hand conversely nevertheless nonetheless yet instead and
in contrast okay in contrast is a very common one same with however so in this case for our example we have however
some people may hold a different viewpoint on this issue so a different Viewpoint than what was discussed
previously so that would indicate to us that we would be looking for a contrast there next let's talk about cause and
effect so we would state in our previous sentence that we had some sort of cause and then in the sentence that we were
transitioning to we have our effect so as a result stating as a result of what came before consequently as a
consequence of what came before therefore thus for this reason hence so consequently so as a consequence of
what came before thus what came after consequently the company experienced a significant growth so
before this we would probably expect to have something like the company changed um its leadership to focus on growth or
something like that and then as a result of them changing the leadership the company experienced significant growth
all right sequence and time uh this one's also fairly common so you would use this if you are going in sort of a
progression so we have next then sub quently or in other words what came after or you know the next thing uh
afterward meanwhile simultaneously simultaneously be at the same time finally eventually ultimately an example
would be afterward we proceeded to analyze the gathered data all right now let's talk about how you would
transition if you are giving an example so you would use for instance to illustrate specifically a case in point
as an example to demonstrate an example of this would be four instance so you you will often see for instance or for
example those are probably the two most common versions of this so for instance many successful companies started as
small startups okay so before this we could have some sort of claim that um successful companies don't just arise
from spin-offs of large corporations and then we say for instance many successful companies started as small startups
obviously small startups is different from a spin-off from a major corporation okay so we'd be providing an example to
that claim all right question number or number seven comparing and contrasting so we've already kind of talked about
contrasting in this case we'll talk about comparing there are some in here that are kind of repeats from
contrasting but um this is kind of two very similar things so I did categorize them together so we have similarly okay
so something similar to what came before likewise pretty much the same similar layer if something's like what came
before it in the same way very similar to the first two on the contrary so this would be contrast however which is a
contrast conversely which is a contrast in contrast which is obviously a contrast and then on the other hand
which is also a contrast okay in this case likewise we are doing something that's similar okay so likewise the
second study also found users preferred option A to option b so presumably the sentence that came before it would be
something stating that we had study a or the first study found users preferred option A to option b okay and then we're
stating likewise the second study also found users preferred option A to option b all right summary and
conclusion so in conclusion to sum up overall in summary okay so an example would be in conclusion the findings
strongly support our hypothesis so you would use the if you are coming to a conclusion or you are stating a summary
of what came before all right emphasis okay some examples of emphasis would be indeed okay indeed is probably the most
common example of emphasis you have notably specifically in fact and particularly an example would be indeed
the data supports the hypothesis that was initially proposed finally we have a comparison of
options some examples would be whereas okay so we State something that came before it and then we have another
option we would State whereas option for an example would be we would say option one is a mediocre option whereas option
two is a superior option next we have in contrast to so once again that can also be used as a comparison of two different
things on the other hand once again that can also be used as a comparison and as a as a
contrast alternatively okay You' provide some sort of alternative something that came before it and then conversely which
once again can be used as a contrast as well okay an example would be alternatively we can consider a
different approach to solve this problem remember transitions are not just words or phrases to be inserted randomly in
your writing okay they need to actually serve a purpose okay they serve a signpost to guide your Reader through
your ideas helping to create a logical and coherent flow all right lastly let's talk about subjunctives subjunctives are
used to express hypothetical or unreal situations wishes recommendations and emotions here's a more detailed
explanation of when and how to use subjunctives all right number one use of were and hypothetical statements in
hypothetical or contrary to fact situations use were instead of was after the pronouns I he she and it okay
example one if I were a bird I would fly freely in the sky we wouldn't state if I was a bird we would state if I were a
bird I would fly freely in the sky okay keep in mind this is a hypothetical obviously I am not a bird if you look at
example two she speaks as if she were the queen okay once again this is hypothetical as if okay she's not
actually the queen so we State she speaks as if she were the queen okay keep in mind that this is different from
what You' expect respect when you're just straight up matching the number of your verb to the number of your subject
because obviously if we were just doing that we would State she was but we have to take account for the fact that this
is a subjunctive we are in a hypothetical okay as if she were the queen she's not actually the queen this
is hypothetical so we have to keep in mind that we need to use were instead of was after the pronouns I he she and it
all right number two use use of the base form of the verb after certain verbs after certain verbs of recommendation
request suggestion or necessity use the base form of the verb infinitive without to to express the subjunctive mood an
example would be it is important that he arrive on time once again this is a this is a difference from when you are just
strictly matching the number of your subject to the number of your verb if we would State he arrives and we would
State they arrive but because we are in the subjunctive we would state it is important that he arrive on time so once
again you need to pay close attention to if you're in the subjunctive or if you are not example number two the teacher
insisted that we study for the exam okay now let's talk about the use of past subjunctive form for wishes or
desires so when expressing wishes or desires about unreal or unlikely situations in the past or in the present
or past use the subjunctive form of the verb I wish I were taller it would be an example of that example two she wish she
wishes she had studied harder for the test all right number four use of War to for unlikely or hypothetical future
events to indicate unlikely or hypothetical future events used the phrase War to followed by the base form
of the verb now if you are someone who grew up in the US um and who you know spoke English you know throughout their
childhood this should come pretty naturally okay an example would be if it were to rain tomorrow we would have we
would have to cancel the picnic okay so once again we are in that hypothetical okay and in this case we're in the
hypothetical future event okay if it were to rain tomorrow future we would have to cancel the picnic suppose I were
to win the lottery what would you do once again this would be a hypothetical future event okay if I were suppose I
were to win the lottery that's future and hypothetical we say I were to okay it's important to use subjunctives
carefully and appropriately in formal writing subjunctives are often used in more formal or literary text and can add
depth and Nuance to your writing by understanding when and how to use subjunctives you can effectively convey
hypothetical situations wishes recommendations and emotions in your writing all right this SAT writing guide
covers the various aspects of grammar sentence structure word use punctuation and coherence in writing it's important
to study and understand these rules in order to improve writing skills and achieve a higher score on the SAT
writing section and I will add on to that that it's important to practice and get practice and Reps under your belt
seeing these questions and applying what was covered here now let's talk about how to approach different types of SAT
writing questions by knowing which approach you want to use for certain questions you'll be able to be more
efficient and comfortable when taking the test here's how I recommend that you approach questions on the digital SAT
writing section that ask you to complete the text so it conforms to the conventions of Standard English
what I want you to do is take a look at your answer choices first and identify what you ultimately need to discover or
identify as you do your initial read through in order to answer the question so in this case when we glance at our
answer choices we see that they are all pronouns they one you and it are all pronouns so now what I'm going to do is
as I do by read through I'm going to be looking for what the noun is that I'd be replacing with this pronoun so let's go
ahead and read through we have public awareness campaigns about the need to reduce single euse Plastics can be
successful says researcher Kim Borg of monach University in Australia when these campaigns give consumers a choice
for example Japan achieved a 40% reduction in plastic bag use after cashiers were instructed to ask
customers whether and now we have a pronoun here blank wanted a bag Well we'd be asking the customers whether
they want a bag okay and as you can see customers is plural and since customers is plural the pronoun that replaces it
cannot be singular so our answer would have to be a since that is the only pronoun out of a c and d which is plural
so as you can see by recognizing what we need to identify during our read through we're able to be more efficient on the
writing section here's a second example of how I recommend approaching questions that ask you to complete the text so it
conforms the conventions of Standard English so same approach you're going to start by looking at your answer choices
identify what the difference is between all of them in this case we see its punctuation so now what we're going to
be looking for as we go through the text and read it is do we have an independent clause before this punctuation do we
have an independent clause after it what kind of phrase or Clause do we have after it what kind of phrase or Clause
do we have before it so you have in ancient Greece an epicurian was a follower of epicurus a philosopher whose
beliefs revolved around the pursuit of pleasure epicurus defined pleasure as the absence of pain in the body and of
trouble in the soul okay so that's an independent clause next we have positing that all of life that all life's virtues
derived from this absence that is not an independent clause okay that's a participle phrase now one thing you can
note is that if you have something that or a phrase that ends in or if you have a word that ends in ing or Ed that
starts off a phrase okay there's a decent chance you might be looking at a participle phrase so understand that so
in this case we have this ing okay so that's indicative that you should be looking for a participle phrase and in
this case we do have one now a par participle phrase is not an independent clause since it's not an independent
clause we can get rid of D next between B and C we see that one uses a colon one uses a semicolon however when you're
connecting a participial phrase to a main Clause you would either use a comma an M Dash or no punctuation if it's inte
if it's already integrated okay so you would not be using a colon or a semicolon in this case we use a comma
which is perfect okay so our answer would have to be a so once again key thing to recognize with a question like
this which is just the question type of complete the text or conforms the conventions of Standard English Begin by
taking a look at your answer choices identify the differences identify what you need to look for before you do your
read through of the text and then as you do your read through of the text identify what it is that you were
searching for in this case it's was there an independent clause um before this Punctuation is there an independent
clause or what kind of phrase are we dealing with afterwards and then identify the correct punctuation for
that because this question type is so common on the digital SAT writing section I want to give a third example
of it so we have Which choice completes the text what conforms to the conventions of Standard English it'll
Begin by taking a look at your answer choices again in this case we see the difference is whether we you're using
they are it is their which is plural and possessive its which is singular and possessive okay so let's go and take a
look we'll go through we'll identify what we're looking for in this case we're looking for what is the number of
our subject and is it possessive Okay so we've got British scientists James Watson and Francis Crick won the Nobel
Prize in part for their 1953 paper announcing the double helix structure of DNA but it is misleading to say that
Watson and Crick discovered the double helix okay and then we have blanks findings we based on a famous x-ray
image of DNA fibers photo 51 developed by x-ray crystallographer rosand Franklin and her graduate student
Raymond Gosling well the subject is Watson and Crick okay so two people so we have a plural subject so we can get
rid of B and we can get rid of D now keep in mind that it is their findings they do own the findings it is
possessive so plural and possessive means our answer there would have to be C option A is they are which is not
possessive okay option C is plural possessive so our answer would have to be C because this question type on the
digital SAT writing section is so common I'm going to go ahead and give a few more examples so we have answer choices
a through D is where we're going to start we're going to identify the differences between them okay you have a
comma here and here but not here and here we have commas in options a b and d after chin but not in option C and then
we have commas after claim so ultimately I'm looking for a couple things first thing I'm going to look for is if steina
chin is non essential because that would get rid of options A and B or C and D depending on whether it is not essential
or not okay and then the next difference I'll be looking for is if I need to have a comma after claims so it looks like if
we look up claims is before this quote so whether or not that quote is integrated or not if it's integrated we
will not need a comma if it is not integrated then we would need a comma so let's go ahead and take a look we've got
in 1937 Chinese American Screen Actor anime Wong who had portrayed numerous villains and secondary characters but
never a heroin finally got a starring role in Paramount Pictures daughter of Shanghai a film that critic steina chin
claims expanded the range of possibilities for Asian images on screen all right we've got a film that critic
steinach chin claims expanded the range okay if we were to remove steinach chin we would have a film that critic claims
expanded the range Well we'd have to say a Critic if we're going to remove steinich and we couldn't just say critic
claims we'd have to say a Critic claims okay so we can go ahead and get rid of A and B because we know that it is
essential okay the meaning would change if we were to remove sinish in let's go and take a look at C and D we have
critic stach chin claims and then we go straight into the quote versus a comma before claims and a comma after claims
well we already know we don't need a comma before claims so just based on that we could get rid of D but I also
want to just add an option e here and let's talk about what the case would be if we had um critic
steina chin um claims and then a comma okay so let's just pretend that this would was
an option as well well if we go up we've got a film that critic steinach chin claims expanded the range of
possibilities for Asian images on screen as you can see that's already integrated into the text which means that since
it's integrated into the text we do not need a comma there okay so e would also be incorrect if that were to be some
answer Choice okay so our answer there would have to be answer Choice C okay so once again to kind of sum all of this up
okay We Begin by looking at the differences in our answer Choice there we identify what we need to look for in
the question as we do our read through once we identify those things we come down we eliminate wrong answer choices
and get to the right one here's another example of how I recommend you approach questions that ask you to conform to
conventions of Standard English so I'd start by taking look at my answer choices in this case we've got a version
of claim in all of them so what I'll be looking for is my subject I want to know the number of my subject and I also want
to know what tense I'm in so let's go ahead and go through number 23 in 1637 the price of tulip Skyrocket in
Amsterdam with single bulbs of rare variety selling for up to the equivalent of $200,000 in today's US dollar some
historians blank okay so we got historians as our subject that this tulipmania was the first historical
instance of an asset bubble which occurs when investors Drive prices to high is not supported by actual demand all right
so before this comma we need to have an independent clause okay so in order to have an independent clause we need to
have a finite verb after historians okay so let's take a look at our options we got option option A some historians
claiming that this tulip Mania was the first historical instance of an asset bubble okay now since we don't have an
independent clause following this comma we cannot we cannot use claiming here okay
because if we were to say some historians claiming that this tulip Mania was the first historical instance
of an asset bubble that's just not an independent clause okay so we can get rid of option A we would have some
historians claim that this tulip Mania was the first historical instance of an asset bubble that would make an
independent clause and claim is a finite verb okay so we have an independent clause in B so B will be our answer
there let's take a look at C and D as well we've got option C some historians having claimed that this tulip Mania was
the first historical instance of an acid bubble this prevents essentially very close to the same problem as a we are
using a nonfinite participle and this will not complete an independent clause so if we were to use having claimed we
would not have an independent clause before the comma okay and if we're going to have a sentence we need to have an
independent clause so we can get rid of option C if we had to take a look at option D okay we would have some
historians to claim that this tulip Mania was the first historical instance of an asset bubble once again that would
not make an independent clause okay to claim there is a nonfinite infinitive so we can get rid of because once again we
would not have an independent clause the only option out of a c and d that would give us an independent clause prior to
this comma right here okay is option b because it provides a finite verb here's another example we have Which choice
completes the text so it conforms to conventions of Standard English I look at my options I've got food with a colon
a comma no comma and well or nothing no punctuation after it okay so what I'll be looking for is do I have an
independent clause before food and then what kind of phrase or Clause do I have after food so we have researchers
studying Mago sensation have determined why some soild Dwelling ground worms in the Southern Hemisphere move in the
opposite direction of Earth's magnetic field when searching for food that's an independent clause before food so I'm
going to Mark I see at food after that we have in the northern hemisphere the magnetic fields Point down into the
ground but in southern hemisphere it points up toward the surface and away from worms food sources okay that's also
an independent clause so we have two independent clauses we cannot connect them with just well or with no
punctuation or with just a comma so our answer there would have to be answer Choice a here's another example with
question 25 Which choice completes text and forms Convention of Standard English start with the answer choices we got a
bunch of pronouns so I'll be looking for the noun I'm replacing got scientists believe that unlike most other species
of barnicle interal barnicles can dissolve the smell like secretions they used to attach blank to a turtle
seashell enabling the Barnacles okay so ultimately I'm our subject here is the turtle Barnacles okay so that's the noun
we need to replace Turtle Barnacles can dissolve the smutling secretions they Ed to attach so have to be them themselves
to a sea turtle shell we know it's plural so obviously we would get rid of a and we would get rid of D okay we know
it has to be themselves because we wouldn't state that Turtle Barnacles can dissolve the SMC secretions they use to
attach them to a sea turtle shell okay it is themselves okay so our answer there half beb here's another example
how I recommend approaching questions where you ask to conform to the conventions of Standard English in this
case I'll look at my answer choices to start I've got a bunch of different forms of the verb allow so what I'm
going to be looking to do is identify the number of my subject and also try to pay attention to tense as I read through
this we have a classic children's board game Shoots and Ladders is a version of an ancient nepes game parapata soap in
both games players encounter good or bad spaces while traveling along a path landing on one of the good spaces blank
a player to skip ahead and arrive closer to the end goal right so I want to identify my subject I have this
prepositional phrase of on one of the good spaces where on is the preposition that starts it off so in order to
identify your subject make sure that you are getting rid of those prepositional phrases so our subject here is landing
Landing is going to be singular look at my options I have option A allows I'll use the he they test here so I would
State he allows but I would State they allow so I see option D would have to be incorrect since allow is plural but
allows is singular if look at option b we have are allowing well are allowing we State they are allowing but he is
allowing so we know that that's plural so can get rid of that as well if look at C we have have allowed we would State
they have allowed but he has allowed so once again we see C would be plural as well so answer there would have to be
option A since we need to maintain that Singularity that is in our subject to the singularity that must match with our
verb so our answer there would have be a here's another example so if we take a look at our answer choices we've got
equations and though anytime I have a transition word like though or however I'm going to be looking to see if it
needs to be on the left side of whatever punctuation or the right side or in other words does it need to be contained
with the first independent clause or the first clause or does it need to be with the second clause or phrase okay so
that's one thing I'll be looking for the second thing is we have a colon here we have just commas here with no Fanboys
and we have no Fanboys or commas or any punctuation in D and then option C we have a period so what I'm going to look
for is if we have two independent clauses because that'll help me figure out punctuation as well so I'm looking
where to place though and then if we've got two independent clauses in 1943 in the midst of World War II mathematics
professor Grace Hopper was recruited by the US military to help the war effort by solving complex equations Hopper's
subsequent career would involve more than just equations though as a pioneering computer programmer okay and
as a pioneering computer programmer is an introductory modifier to hopper Hopper would help usher in the digital
age that's an independent clause we also have an independent clause with Hopper's subsequent career would involve more
than just equations so we have two independent clauses okay we can't connect them with a comma and no Fanboys
or with no punctuation so we get rid of B and D so now the question is does though need to come or be attached
basically to the first independent clause or the second well we have Hopper subsequent career would involve more
than equations though okay that would need it be applied or connected to the first independent clause we wouldn't
State though and then have the introductory modifier after that though as a Pioneer and computer programmer
Hopper would help Usher in the digital age okay that would make sense we have to have that though connected to this
first independent clause okay the other thing that you can note is that your second independent clause here of as a
Pioneer and computer programmer copper would help Usher in the digital age is illustrating the idea that came before
it or the preceding idea prior to this colon which is that her subsequent career would involve more than just
equations which we are illustrating okay by her being a computer programmer okay the equations part was referring more to
her being a mathematician so we are illustrating this idea anytime you are illustrating the idea that came before
it okay you will often be using a colon okay so answer has to be answer Choice a here's another example so if I take look
at my answer choices here I've got Henry resumed his reign the reign of Henry resumed Henry's Reign resumed and it was
Henry who resumed his Reign so as you can see here basically what's getting switched around is what's at the
beginning first you have Henry then you have the reign of Henry then you have Henry's Reign then you have it was Henry
if you see that your subject is just being like turned and switched around in the beginning you're probably going to
be looking at an introductory modifier so in this case if I take a look back up at where my blank is I have a pawn
recovering two years later okay that's an introductory modifier so what comes after it needs to be who it is modifying
who is recovering 2 years later okay so let's go ah and read through our text figure out who that is we have in 1453
English king Herer the vi became unfit to rule after falling Gravely ill as a result Parliament appointed Richard
third Duke of York who had a strong claim to the English Throne to rule as protector P covering two years later
what we know that King Henry is the one who fell ill so he would be the one recovering so what needs to come after
this comma is King Henry so we have option A Henry which is the subject that this introductory modifier is modifying
okay we have option b the reign of of Henry it's not the reign of Henry that is recovering 2 years later it's not
Henry's Reign that is recovering 2 years later and it's not it that is recovering two years later it is Henry himself okay
so we need to have the correct subject after the introductory modifier so our answer there has to be answer Choice a
here's how I recommend that you approach transition questions on the digital SAT writing section if you take a look at
question n it says Which choice completes the text with the most logical transition now in contrast to questions
that ask you to conform to the conventions of Standard English I actually recommend that you don't look
at your answer choices first when dealing with transition questions here's how instead I think you should approach
it start by reading through the text although novels and poems are considered distinct literary forms many authors
have created Hybrid Works that incorporate elements of both okay so here we have a claim that many authors
have created Hybrid Works that incorporate elements of both both being the poems and the novels then we have
Bernardine avisto the emperor's babe blank is a verse novel a book-length narrative complete with characters and a
plot but conveyed in short crisp lines of poetry rather than Poe okay so this is an example of how novels and poems
are not necessarily distinct but instead how many authors have created Hybrid Works that incorporate elements of
poetry and a normal novel or in other words a normal narrative okay so as we can see we are providing an example of
the claim that we are given above okay so I'd be looking for something like for example okay so D would be perfect there
now the reason I recommend that you um you don't look at your answer choices first is because that could potentially
sway you before you go through and you read the actual text so I recommend you try to come up with your own answer
Choice first and then take a look at your options that way you're less likely to be swayed by wrong answer choices
here's another example once again we have Which choice completes the text to most logical transition we'll start by
reading through at 2 weeks old the time their critical socialization period begins wolves can smell but cannot yet
see or hear domesticated domesticated dogs can see hear and smell by the end of two weeks okay so in this case we
have a contrast we have at two weeks old wolves can smell but they cannot see or hear but domesticated dogs can see hear
and smell by the of TW weeks so looks like we have a contrast we'll keep reading this relative lack of sensory
input may help explain why wolves behave so differently around humans than dogs do from a very young age wolves are more
wary and less exploratory so in this case we do have a contrast so I'd be looking for something like domesticated
dogs by contrast can see hear and smell by the end of two weeks as we can see we have by contrast as an option so that
works out perfectly okay so our answer would have to be c one thing I will make note of is that with digital SAT writing
section and the SAT writing section before it went digital you tend to get um very similar transition choices and
you tend to have similar transition themes across the different practice tests now what I mean by this is you
will often see situations where you would use something like for example or something exemplifies what came before
it or a contrast or something where you're stating something in other words or where you're giving you know
something for instance which is kind of similar to for example um and some other ones that you might see are consequently
subsequently consequently being if something is a consequence of what came before subsequently being if something
came after what was talked about previously so getting practice with the transition questions is very very
helpful because you often see similar transitions being used across the practice tests which is obviously going
to be indicative that those transitions are ones that the College Board would want you to know for the actual digital
sat here's another example so once again we have Which choice completes the text most logical transition I'll start by
filling in the blank with what I expect to be there after I do my read through and then I'll go through my answer
choices we have researchers Helena miljevic Brandt Lucia Santa Maria and Marco Tony report that well
mathematicians may have traditionally worked alone evidence points to a shift in the opposite direction so one thing
I'll point out here is anytime I have any sort of shift or any sort of um you know indication that we have some sort
of change going on or even some sort of something that's staying the same I want to pay attention to that on a transition
question in this case we have a shift in the opposite direction of working alone so presumably working together then we
have mathematicians are choosing to collaborate with peers a trend illustrated by the rise in the number of
mathematics Publications credited to multiple authors okay so in this case we are stating that they are choosing to
work with peers that's pretty much an example of what came before so I would probably be looking for something along
the lines of four example here okay if we look at our options we get option A similarly well it's not similar to what
came before okay we're just kind of illustrating what we previously claimed if we look at option b for this reason
it's not a consequence of what came before it so we can get rid of B okay what came before it did not cause
mathematicians choosing to collaborate with their peers if we look at option C furthermore we're not adding on to what
came before we're illustrating it okay if we look at option D we have increasingly okay increasingly
mathematicians are choosing to collaborate with their peers a trend illustrated by the rise in the number of
mathematics Publications credited to multiple authors so as you can see D would have to be our answer there now
obviously that's not the same as what I came up with as for example but when we state that increasingly mathematicians
are choosing to collaborate with their peers well is that a good transition from what came before which stated that
we are moving in the opposite direction of working alone yes because the opposite of working alone would be an
increase in collaboration okay so obviously that's a great transition there and it is illustrating what came
before okay so our answer would have to be D here's how I recommend answering questions on the digital SAT writing
section where you're presented with a students or someone's notes and then you have to answer questions following that
first thing I recommend that you do is take a look at what your actual prompt is okay and the prompt will basically be
the last part before Which choice most effectively uses relevant information from the notes to accomplish the goool
so when I say prompt I'm referring to the section right here okay so the student wants to present the study and
its findings from here once I know the prompt and identify what I want to look for as I do my read through in this case
it's pretty broad it's just the study and its findings okay so I'll go back up let's do the read through okay petaurus
were flying reptiles that existed millions of years ago in 2021 study act analyzed fragments of pterosaur jaw
bones located in the Sahara Desert she was initially unsure if the bones belong to a juvenile or adult petaurus she used
Advanced microscope techniques to determin that the bones had few growth lines and relative few growth lines
relative to the bones of fully grown bosur she concluded that the bones belonged to juveniles okay so the
findings is that the bones belong to juveniles okay the study is ultimately whether these um these jaw bones are
from that of a juvenile or an adult okay so let's go ahead and look at our options we got option A
in 2021 uh CT studied potur jaw bones and was initially unsure if the bones belonged to juveniles or adults that
does not present the findings so we can get rid of option A when you're dealing with questions like this you need to be
strict and make sure that you're answering all parts of the prompt this one does not include findings we get rid
of a b the jaw bones located in the Sahara Desert where the focus of a 2021 study also does not talk about the
findings option C in a 2021 study CT used Advanced microscope techniques to analyze the jaw bones of potur flying
reptiles that existed millions of years ago once again we do not discuss the findings in option C so we got to get
rid of it and then we take a look at option D in a 2021 study CT determined that potur jaw bones located in the
Sahara Desert had a few growth lines relative to the bones of fully grown potur and thus belong to juveniles okay
right there we do both a presenting of the study if we go up our prompt present the study and its findings we do both of
those answer there has to be D here's another example of how I recommend that you approach questions where you're
given a set of notes and asked to do something with it in this case we see that our prompt is the the student wants
to compare the two women's contributions to the March on Washington and then we have the generic part of the question
which is which Choice most effectively uses relevant information from the notes to accomplish this goal okay so we're
going to focus in right here student wants to compare the two women's contributions to the March on Washington
so since I'm looking for a comparison I'm going to look for things that are different and possibly things that are
the same as well so we have African-American women played prominent roles in the Civil Rights Movement
including at the famous 1963 March in Washington civil rights activist Anna hedgman one of the March's organizers
was a political adviser who had worked for President Truman civil rights activist Daisy Bates was a well-known
journalist and advocate for school desegregation so it looks like they have two different positions then we have
hedgman worked behind the scenes to make sure a woman was included in the lineup of speakers at the March Bates was the
sole woman to speak delivering a brief but memorable address to the cheering crowd qu so hedgman worked behind the
scenes and Bates was a speaker looks like it's the main difference there the similarity would be that they both had
important contributions to the march in Washington so you've got option A hedgman and Bates contributed to the
march in different weights in different ways Bates for example delivered a brief but
memorable address all right so are we comparing the two women's contributions well we say that they contributed in
different ways and then we only state the way that Bates contributed I would prefer an option where we talk about the
way that they each contributed um in their own distinct way so I'm going to leave this one as neutral for now let's
take a look at B hedgman worked in politics and helped organize the Mars while B Bates was a journalist and
school desegregation activist advocate well we never mentioned bates's role in the March on Washington there so I'm
going to get rid of B option C States although hedgman worked behind the scenes to make sure a woman speaker was
included Bates was the sole woman to speak at the March okay this is much better than option A okay option A
States they both contributed to the march in different ways but then we only um discuss how Bates contributed K so we
can get rid of a now Okay C is much better because it states how hedgman contributed okay she worked behind the
scenes to make sure woman was included and then we also discuss how Bates contributed being the sole one to speak
at the margin obviously these are both different so that's a great comparison okay we can take a look at d as well
here we have many African-American women including baates and hedgman fought for civil rights but only one spoke in the
March the focus here is not on comparing baits and hedgman so we can get rid of D keep in mind you're prompt prompt States
the student wants to compare the two women's contributions specifically to the March on Washington so our answer
there would have to be answer Choice C now let's talk about how to approach different types of sat reading questions
by knowing which approach you want to use for certain questions you'll be able to be more efficient and comfortable
when taking the SAT here's a tip on how to answer one of the most commonly asked questions on the digital sat reading
section if you take a look at the prompt it states which always completes the textt with the most logical and precise
word or phrase what I recommend doing when you see a question with that type of prompt is start by reading from the
beginning and then once you get to this blank right here fill it in with what you think should go there now that might
require that you continue reading on but ultimately what your goal should be is to fill in the blank with a word before
you actually take a look at your answer choices this is important because it'll help you avoid being swayed by what the
answer choices say so let's go and illustrate this with question one former astronaut Elena choa says that although
she doesn't have a definite idea of when it might happen she blanked that humans will someday need to be able to live in
other environments than those found on Earth this conjecture informs her interest in future research Miss
missions to the Moon okay well if she has interest in future research missions to the Moon I would assume that she
believes that someday humans would need to be able to live in other environments than those found on Earth okay so I
would fill in right here with believes now at this point I would then take a look at my answer choices so I have
answer Choice a as an option which is it demands well we can't say that she demands humans will someday need to be
able to live in other environments because obviously she cannot demand that we have B speculates she speculates that
humans will someday need to be able to live in other environments than those found on Earth and that would make sense
because it informs her interest in future research missions to the Moon okay so that makes a ton of sense if we
take a look at C doubts well she obviously doesn't doubt it because she's interested in future research missions
to the moon and she cannot establish it to establish something would basically be to prove something she's unable to
prove that humans will someday need to be able to live in other environments and those found on Earth qu or answer
would have to be be speculates and as you can see by filling in this blank with a word before we actually take a
look at our answer choices we're much less likely to be swayed by what they say because we already know what should
fill in that blank based on the context of the question here's another example with question two beginning in the 1950s
Navajo Nation legislator Annie Dodge wanka continuously worked to promote Public Health this blank effort involved
traveling throughout the vast Navajo Homeland and writing a medical dictionary for speakers of Dyan bad the
Navajo language all right I would say this consistent effort okay we say that she continuously worked to promote
Public Health then we go on to talk about her effort which involved traveling throughout the Homeland
writing medical dictionary so obviously this is a consistent effort so that's what I'd fill in there before taking a
look at my answer choices now if we take a look at our options we have a and partial well there's not any sides to be
taken here so you can't have a neutral stance on something that doesn't have two sides so that wouldn't make sense we
have B offhand offhand would have a negative connotation so that wouldn't make sense here either if we take a look
at C persistent okay persistent and consistent very very similar in meaning okay both in this context would
basically mean that there is a consistent or um continued effort involv um by Annie okay so that would make a
lot of sense we take like a d mandatory no one is forcing her to do that so that wouldn't make sense okay so our answer
would be C here's how I recommend you approach digital sat reading questions that ask you to State the main purpose
or the main idea of text so to illustrate this I'm going to use question number seven in 2007 computer
scientist Louis vanan was working on converting printed books into a digital format he found that some words were
distorted enough that digital scanners couldn't recognize them but most humans could easily read them based on that
finding vanan invented a simple security test to keep automated Bots out of websites the first version of the
recapture test asked users to type one known word and one of the many words scanners couldn't recognize correct
answers proved the users were human and added data to the book digitizing project so for main purpose and Main
Idea questions what I recommend you do is come up with your own answer before taking a look at the answer choices that
way you're not easily swaye by an choices that are close to correct but have slight flaws in them that actually
make them incorrect so let's go and start by coming up with our main purpose for this prompt okay so ultimately we
start out by talking about how um vanan was using digital scanners and how it couldn't recognize some of the words
then we talk about how he uses this to create the recapture test and then we talk about the application of the
recapture test and how it's used to protect websites so ultimately it's really about the creation of the
recapture test okay so let's take a look at our options now that we've just identified the main purpose as the
creation of the recapture test so we have option A to discuss van On's invention of recapture okay that looks
perfect we'll put a check by that let's take a look at BC and D we have B to explain how digital scanners work okay
obviously that's not the main purpose okay we don't even really discuss necessarily that much about digital how
digital scanners actually work we just mentioned them in the beginning and talk about how they can't actually recognize
some of the words but that's really just to introduce how they came up with the recapture test so just to lead us to the
creation of it we have C to call attention to Van On's Book digitizing Project the focus isn't on his book
digitizing project okay that's just how he ended up discovering or creating recapture okay so we can get rid of C as
well there if we take a look at D we have to indicate how popular recapture is okay once again that is not um
ultimately the main purpose now do we State anywhere even that it is popular okay we say that if we go up he invented
a simple security test to keep automated bots on a websites we don't even necessarily mention that it is popular
now some of us may know this from just our general knowledge of what goes on on the internet but we have to acknowledge
that the main purpose here is talking about the creation of recapture okay so our answer has to be a now you'll notice
by coming up with our own answer for the main purpose first it helped us to be able to eliminate answer choices that
were similar or were mentioned at somewhere in the text but weren't actually the main purpose but were just
maybe a step to get us to the main purpose here's another example of how I recommend approaching questions that ask
you about the main purpose or main idea on the digital sat reading section so I'm going to illustrate this with
question 11 the following text is from Maggie poke Johnson's 1910 poem poet of our race in this poem the speaker is
addressing Paul Lawrence Dunbar black author thou with stroke of Mighty pen Hast told of joy and mirth and read the
hearts and souls of men as cradled from their birth the language of the flowers thou H has rested them all and I the
Little Brook responded to thy call okay so we're going to start out by coming up with our own main purpose before
actually taking a look at your choices that way we're not as SED by an choices that are close to correct but have
slight flaws that actually make them incorrect so let's go and start by discussing what the main purpose of this
is let's start with this first part okay so we have thou with stroke of Mighty pen has told of joy and mirth and read
the hearts and souls of men as cradled from their birth okay so we're ultimately complimenting um Paul
Lawrence dunbar's work as a poet stating that he's told of joy and mirth read the hearts and souls of men so essentially
stating that um he's very in tune with obviously The Souls of men or in other words um the soul really representing
you know the inner thoughts of people sort of who they are deep deep down in their soul we have as cradled from their
birth so from um from their birth presumably until death and we take a look at the second part we have the
language of the flowers thou Hast read the all and E the Little Brook responding to thy call okay so here
we're talking more so about nature okay so presumably this is a poet who is talking both about uh humans and nature
um clearly it sounds like they are very in tune with both of them K has read them all all the language of the flowers
so very great at writing um both about humans and about nature okay so main purpose I would sayate is that Paul
Lauren Dunbar is an incredible poet who's great at writing both about um humans maybe The Human Experience as
well as nature so we have option A to praise a certain writer for being especially perceptive regarding people
in nature okay as you can see that's very supported by the text okay that's also in line with the main purpose that
we came up with before taking a look at the answer choices that looks really good we'll take a quick look at b c and
d as well we have B to EST that a certain writer has read extensively about a variety of topics well that's
not the main purpose okay and we're also not explicitly stating or there's no real support for that the certain writer
has read extensively about a variety of topics okay this is pretty much all figurative language if we scroll up and
take a look at the poem so there's really not any support for that being the main purpose um ultimately the main
purpose is that um they are especially perspective regarding people in nature right we talk about how um they have
told of joy and mirth read the hearts and souls of men and that's really the key part there hearts and souls of men
okay so that's perceptive about people and then perceptive about nature that language of the flowers that has read
them all okay so tons of support for a if we take a look at C to call attention to a certain writer is careful and
elaborate elaborately detailed writing process we're not discussing the writing process okay if we take look at D we've
got uh to recount fond memories of an afternoon spent in nature with a certain writer okay we never state that this is
from an afternoon they spent together okay so D doesn't have any support our answer there would have to be a as you
can see coming up with our own answer Choice first help us to avoid getting stuck between answers and it also helps
us to get rid of answer choices that seem like they would be close to a correct answer but have slight flaws
that we ultimately can then use to rule them out as incorrect here's some advice on how to answer this really common
digital sat reading question the question states which Choice best describes the function of the underlined
sentence as a whole when you come across a question like this the first thing I'd recommend doing is going ahead and
reading through so let's go and start doing that with question 8 following text is from Edith Wharton's 1905 novel
The House of Mirth Lily Bart and a companion are walking through a park Lily had no real intimacy with nature
but she had a passion for the appropriate and could be keenly sensitive to a scene which was fitting
which which was the fitting background of her own Sensations the landscape outspread below her seemed an
enlargement of her present mood and she found something of herself in its calmness its breath its long reaches
okay so immediately what I'm seeing is before we had a claim okay that she could be keenly sensitive to a scene
which was the fitting background of her own Sensations okay now we are going ahead and showing or proving that claim
okay we have the landscape outspread below her seemed enlargement of her present mood and she found something of
herself in its calmness okay that's very directly supportive of that claim that we had in the previous sentence okay
that she finds something of herself in its calmness or in other words that it's fitting um she's keenly sensitive to a
scene which was the fitting background of her own Sensations okay so obviously that's supportive its breath it's long
free reaches all right let's keep reading on on the nearest slopes the sugar mels wavered like Pires of light
lower down was a massive massing of gray Orchards and here and there the lingering of an Oak Grove all right so
this is pretty much from here down just a description of the setting for the most part so we have Which choice best
describes the function of the underline sentence if in the text as a whole so from here I'd go down to my answer
choices so have option A it creates a detailed image of the physical setting of the scene well it looks like actually
the sentence after the underline one is what is really giving more of a detailed image of the physical setting of the
scene okay so I would go ahead and I would get rid of a if we take a look back at the sentence that is underlined
and I'll go ahead and remove some of this blue so you can see it a little bit better okay we state that the landscape
outspread below her seemed an enlargement of her present mood and she found something of herself and its
calmness it's breath it's long for reaches as you can see that's really not creating a detailed image of the
physical setting okay so we could remove it based on that and one thing I do recommend you do on the SAT reading and
writing section is you can cross out answer choices okay and you can cross them out based on what makes them false
or what makes them incorrect okay so if we take a look at B now it establishes that a character is experiencing an
internal conflict okay well ultimately it's not really establishing that the character is experiencing an internal
conflict okay if we go back up to the underl sentence it says the landscape outspread below her seemed an
enlargement of her present mood and she found something of herself and its calmness its breath its long fore
reaches well here we have it found she found something of herself in its calmness okay so it doesn't sound like
there's much internal conflict there okay it sounds like she would be calms we can get rid of B if we take a look at
C we have it makes an assertion that the next sentence expands on okay well the next sentence is really just a
description of the scene of the setting okay so ultimately we're not making an assertion okay and the next sense is
what obviously not be expanding on that if we take a look at D now we have it illustrates an idea that is introduced
in the previous sentence okay if we go back up in the previous sentence as I pointed out earlier it states that she
could be keenly sensitive to a scene which was the fitting background of her own Sensations okay we then go on to
state that she found something of herself in its calmness its breath its long for reaches okay and the landscape
outspread below her seemed an enlargement of her present mood okay that's ultimately supportive of the
claim that came before it okay so as we can see there our answer would have to be D okay so I think the key things that
I want you to take away from this tip is basically if you have an underlined sentence like this okay be looking for
the role that it plays as you read through here's something you need to watch out for on one of the most
commonly asked questions on the digital sat reading section that question is Which choice best states the function of
the underlined sentence in the overall structure of the text so I'm going to approach this just like I approached the
previous question but then once we get to the answer choices I'm going to show you some common wrong answer choices to
watch out for so we have a study by a team including Finance Professor Madu V suggests that exposure to Sunshine
during the workday can lead to overly optimistic Behavior using data spanning from 1994 to 2010 for a set of us
companies the team compared over 29,000 annual earnings forecasts to the actual earnings later reported by those
companies all right so ultimately we see that we start out here with a suggestion or sort of a hypothesis that exposure to
Sunshine during the workday can lead to overly optimistic Behavior then we talk about how we are gathering the data okay
so right here we have data collection then we have the team found that the greater the exposure to Sunshine at work
in the two weeks before managers spended an earnings forecast the more the com the manager forecast exceeded what the
company actually earned that year so then we have summary okay so we start with hypothesis data collection summary
all right so ultimately if we scroll down we got option A to summarize the result of the team's analysis well that
would be the summary okay and this is one of the common wrong answer choices that I wanted to point out to you guys
is that often times when you have a sentence underlined like this in the text one of the answer choices which is
obviously going be a wrong answer choice is they will select either the sentence before or the sentence after or another
sentence somewhere in the text okay and they will put that down as one of the wrong answer choices so you need to
watch out for that in this case it's the summary which we see is the sentence that is after the sentence that's
underlined okay so we can get rid of a because we know it's not the underlined sentence that's giving the summary it is
the following sentence so always watch out for that if we take a look at B we have to present a specific example that
illustrates the stud's findings so this is more so of a misinterpretation okay so I would identify this as a Mis
interpretation wrong answer choice and the reason I identify it as that is because some people would look at this
underlined text and they would think that it is a specific example illustrating the study's findings but
it's not okay they're talking about how they are collecting this data okay this is not a specific example either because
ultimately okay we're looking at 29,000 annual earnings forecast so obviously that is not
specific okay also we have to recognize that this is data collection okay this is not providing of an example we are
collecting the data okay so if we look at option b we can get rid of it okay we would classify that in my opinion as a
misinterpretation because this is not a specific example if we take a look at C we have to explain part of the
methodology used in the team study okay often times on the SAT if you see methodology you should probably be
thinking how the experiment or the study is being um set up and how data is being collected okay so that's what you want
to think about when you think about methodology and as you can see in this case that underlined sentence okay
that's describing the methodology used okay they used data spanning from 1994 to 2010 for a set of us companies the
team compared over 29,000 annual earnings forecasts to the actual earnings later reported by those
companies okay that's an example of a methodology okay so C is perfect there we'll take look at d as well okay D
states to call out a challenge the team faced in conducting its analysis the way I would classify answer Choice D is just
as a random wrong answer Choice sometimes on the SAT reading section and this isn't specific to just this
question type this is specific to just generally almost any type of question on the SAT reading and writing section you
may just get some answer choices that are fairly random and this one is fairly random there really isn't any challenge
that's discussed at all in the text anywhere okay so the fact that they would put that there is really just
random okay so we can get rid of d as well there as you can see your answer there will be C what I really wanted to
point out in this is the common wrong answer choices that you will see on questions that asks you to State the
function of underlying sentences in the overall structure of text here's a tip for anyone who struggles with reading
comprehension on the digital sat reading and writing section if we take a look at question 10 we'll start by reading the
question which states according to the text what is true about mother we have the following text is adapted from Edith
nesbit's 1906 novel The Railway children mother did not spend all her time in paying Dole visits to Dole ladies and
sitting doly at home waiting for do Lazi us to pay visits to her she was almost always there ready to play with the
children and read to them and help them to do their home lessons besides this she used to write stories for them while
they were at school and read aloud to and read aloud read them aloud after tea and she always made up funny pieces is a
poetry for their birthdays and for other great occasions okay so in this case on a reading comprehension question like
this you really just have to go to your answer choices there's not much you can do before that okay so we'll go and go
to answer Choice a we have she wishes that more ladies would visit her so the biggest tip that I would have for anyone
who struggles with reading comprehension on the digital sat and the sat in general is you need to try to make it
less about comprehension and more about evidence and textual support okay so if you take a look at option A she wishes
that more ladies would visit her okay the biggest tool have if you are someone who struggles with reading comprehension
is the ability to go back to the text okay so she wishes more ladies would visit her let's see if there's any
textual evidence for that because if there's not we can get rid of it so we have mother did not spend all her time
in paying dull visits to dull ladies and sitting D at home waiting for D ladies to pay visits to her she was almost
always there ready to play with the children read to them and then we talk about the children for the rest of this
okay ultimately is there any evidence that she wishes that more ladies would visit her no there is not so you can get
rid of a okay and one piece of advice for the reading and writing section is when you get rid of an answer Choice try
to get rid of um it based on the part of that's false so she wishes that more ladies would visit her okay there's no
evidence that she wishes that okay you would have to make um you can't even make a reach for that there's not it's
not even like it would be a large reach there's just no textual evidence of support us you have to get rid of a okay
if you take a look at B now birthdays are her favorite special occasion and this is where being strict on the
digital sat reading section is important okay you want to be strict this part right here birthdays are her favorite
special occasion that's what makes be wrong okay and let's say you didn't remember um that she never stated this
well you can go back to the text and you can look for special occasions so let's go and take a look for that or birthdays
in particular okay so if we go back to the text we look for birthdays okay we see right here is the only mention of
birthdays so we have she always made up funny pieces of poetry for the birthdays and for other great occasions okay great
occasions does not mean it's her favorite okay so on the SAT reading section be strict when getting rid of an
choices if it states that it's someone's favorite special occasion but it just states that uh it's a great occasion in
the text you can't make that jump there's not textual evidence of support that their favorite okay now if we take
a look at C we have she creates stories and poems for her children well let's see if we have evidence for that okay if
you're not someone who's great with comprehension go back to the text so creates stories and poems for children
well let's take a look there we have she was almost always there ready to play with the children read to them and help
them do their home lessons besides this she used to write stories okay so we have that she creates stories for them
and while they were at school and read them aloud after tea and she always made up funny pieces of poetry okay so she
made up funny pieces of poetry made up means that she's writing them or creating them okay so she creates
stories and homes for her children we see that that has textual support C would have to be our answer okay and
then D reading to her children is her favorite activity well once again there's no mention of anything being her
favorite activity let's say that you um forgot that you're not great at comprehension you just go back to the
text look for where we talk about reading to her children then okay we have that up here she was almost always
there ready to play with the children and read to them and help them do their home lessons Okay and then after that if
we go down okay it doesn't really look like we're talking about um we talk about reading again here read to them a
lot after tea but once again we don't say that it's her favorite okay so we can get rid of that by being strict on
the favorite part okay so if you are someone who struggles with comp comprehension try to identify the
subject in your answer Choice identify where that subject is in the text okay read that section of the text and then
determine if there is textual evidence to support it if there is not any evidence to support it then it cannot be
correct okay every answer choice on the SAT has to have evidence from the text to support it here's a tip for anyone
who struggles with reading comprehension on the digital sat reading and writing section what I recommend doing is taking
a look at your prompt before you end up reading through the passage and do this each time because then you know what to
look for as you read through and it avoids you having to do a second read through which if you struggle with
reading comprehension you probably would have to okay so based on the text how does Lord Chancellor respond to the
crowd so we're ultimately going to be looking for L Lord Chancellor's response to the crowd as we do our initial read
through so let's goad and start we have the following text is adapted from Louis Carrol's 1889 satirical novel of sylv
and Bruno a crowd is gathered outside a room belonging to the warden an official who represents the Lord Chancellor or
who reports to Lord Chancellor one man who is more more excited than the rest flung his hat High into the air and
shouted as well as I could make out who Roar for the suben everybody roared but whether it was for the suben or not it
did not clearly appear some were shouting bread and some taxes but no one seemed to know what it was they really
wanted all this I saw from the open window of the warden's breakfast Saloon looking across the shoulder of the Lord
Chancellor what can it all mean he kept repeating to himself I never heard such shouting before and at this time of the
morning too and with such unanimity okay so we have his response contained right here okay he states that what can it all
mean okay he kept repeating to himself he's never heard such shouting at this time in the morning so he does know what
it means okay but then he ends with and with such unanimity or in other words such togetherness or closeness okay so
everyone's together but Lord chancer can't make out what they all want all right so that's his response we've got
option A he asks about the meaning of the crowd's shouting even though he claims to know what the crowd wants well
he doesn't claim to know what the crowd wants okay so anytime you have an answer choice on the SAT reading or writing
section that you can get rid of based on a piece of it that is incorrect cross out that piece that makes it Incorrect
and move on you got B he indicates a desire to speak to the crowd okay it never has any sort of portion in the
text that indicates he has a desire to speak to the crowd okay if you didn't remember that for example if you have
bad reading comprehension you would go back to where the response is contained okay which we see is in this bracket of
blue right here if you take a look there you see what can it all mean he kept repeating to himself I never heard such
shouting before and at this time of the morning too and with such unanimity obviously right there there is no
indication he wants to speak to the crowd so you could get rid of B and then C he expresses a sympathy for the
crowd's demands okay well does it ever show that he's expressing Sympathy for the crowd's demands once again it does
not okay so you would get rid of that okay if you weren't sure on that you would go back to that section and notice
how I've narrowed this down to a section so if you are someone who struggles reading comprehension make sure that you
try to narrow down where you need to look back to okay sometimes it'll be in a case like this where you're only
looking at one portion of the text which is his response because you really don't need to focus on the other portions
because you're not asked about them okay in other cases you may have to jump around a little bit more because it may
not be confined to one section of the text okay and now we'll take a look at answer Choice D he describes the crowd
being united that's supported he talks about um and with such unanimity would be the quotation that would support that
even though the crowd clearly appears otherwise okay and then let's say that you weren't sure if the crowd clearly
appears otherwise okay that's actually not contained within this small section it's not confined there okay that one to
find support for you it actually have to go up okay so the crowd appears otherwise everybody roared but whether
it was for the subord or not it did not clearly appear some were shouting bread others taxes no one seemed to know what
they really wanted okay so that would show that the crowd appears otherwise even though he describes the crowd as
being united okay so answer D has a ton of textual support there here's how I recommend that you approach questions on
the digital sat reading and writing section that asks you to support or weaken any sort of claim or hypothesis
I'm going to illustrate this with question 13 question 13's prompt states which finding if true would most
directly support the student's claim in order to answer a question like this you will need to identify the hypothesis or
claim in this case a claim so let's go and start by reading through question 13 and when you go through you want to
identify that claim so we'll mark it with a c when we find it we have born in 1891 to a kicha speaking family in the
Andes Mountains of Peru Martin chambi is today considered to be one of the most renowned figures of Latin American
Photography in a paper for an art history class A student claims so this is very very clear we mark it with a c
that chambi photographs have considerable ethnographic value in his work chami was able to capture diverse
elements of Peruvian Society representing his subjects with both dignity and authenticity so now we'll go
and take a look at our options we have option A shami took many commissioned photographs of wealthy peruvians but he
also prod hundreds of images carefully documenting the people's sites and customs of indigenous communities of the
Andes well that's ultimately supporting the fact that his photographs have considerable ethnographic value and his
work he's capturing diverse elements okay so both the wealthy and the indigenous communities a perubian
society representing a subjects of both dignity and authenticity okay we have he's
documenting the peoples the sites the Customs okay so that would be supportive of the authenticity aspect okay as far
as the dignity aspect the fact that he's taking you know hundreds of images carefully documenting um the indigenous
communities of the Andes okay I'd say that because he's in particular documenting the indigenous communities
as well as the wealthy peruvians but in this case I'm more so concerned with the indigenous communities the fact that
he's documenting both of those okay is showing that he's showing them with dignity okay there's no sort of bashing
or anything like that okay he's both um you know taking these portraits of wealthy as well as the poor with no sort
of partiality to either so he's representing them with dignity authenticity um because of that has
considerable ethnographic Val ethnographic value okay so that looks good we'll take a look at b c and d as
well we have option b Chan's photographs demonstrate a high level of technical skill as seen his strategic use of
Illumination to create dramatic light and Shadow contrast now that they may very well be true however the problem is
we need to directly support the students's claim and the student's claim isn't that chambi is the most
technically skilled photographer okay so we wouldn't want to focus on his technical skill we'd want to focus on
the ethnographic value of the photographs he is taking okay the fact that he's capturing diverse elements
provan Society not on the actual technical skill so this is an example of something that is fairly unrelated to
the actual claim that is being made here we take look at C we have during his lifetime chambi was known and celebrated
both within and outside his native Peru as his work was published in places like Argentina Spain and Mexico so this
answer choice I would actually classify it as you would select this if you had a misinterpretation of part of the text
because if we scroll up when we state that chami photographs have considerable ethnographic value we're not stating
that um himself and him as a photographer is being valued in multiple aspects or parts of the world okay which
is what anro C is trying to sort of that's kind of the claim C is insinuating with its support here okay
saying that Cham is known and celebrated within and outside his native Peru as his work was published in places like
Argentina Spain and Mexico so I'd classify this as a misinterpretation type of wrong answer choice if we take a
look at D we have some of the peoples and places chami photographed had long been popular subjects for Peruvian
photographers well once again we need to keep in mind the claim that we're trying to support okay we know that the claim
is that his photographs have considerable ethnographic value in his work he's capturing diverse elements
proving in society representing the subjects with both dignity and authenticity okay no part of D is
ultimately supportive of that okay D is really just stating something it's just stating that some of the peoples and
places Jim photographed have been long popular subjects for provan photographers that's not supportive of
the claim okay and also one thing I also want to point out here is you need to directly support the claim the word
directly there is important okay because you have to keep in mind your answer Choice must directly support it can't
just be um you know some sort of tangent that is a reach to support it needs to directly support and the only answer
choice that does that here is answer Choice a so the big takeaway I want you to have from this type of question is as
you read through identify that claim or that hypothesis that you either need to support or weaken here are some common
wrong answer Choice types to questions that ask you about findings that either support or weaken a researcher's
hypothesis or someone's claim okay so I'm going to illustrate this with question number 16 so to start we're
going to first identify what the research of hypothesis is as we do our read through R question 16 and then
we'll get into the answer choices so we have in the mountains of Brazil BT and BM two plants in the velio family
establish themselves on soiless nutrient poror patches of Quartzsite Rock plant ecologists Anna a and Patricio debitto
Costa used microscopic an nails to determined that the roots of BT and BM which grow directly into the cord site
have clusters of fine hairs near the root tip further analysis indicated that these hairs secrete both malic and
citric acids the researchers hypothesize so now we have our hypothesis I'm going to mark this with an H that the plant
depend on dissolving underlying rock with these acids as the process not only creates channels for continued growth
but also releases phosphates that provide the vital nutrient phosphorus okay so now we have to find support for
that hypothesis I'll try to leave that hypothesis within the frame so you can still see it we have option A other
species in the velocci family are found in terrains with more soil but have root structures similar to BT and BM okay
ultimately this is pretty unrelated to the actual hypothesis at hand here okay our hypothesis is that
the uh plants depend on dissolving underlying rock with these acids um because that they then use this to
release phosphates that provide the vital nutrient phosphorus well if you have the same family there are other um
other species in the same family that have root structures that are similar but are found in terrains with more soil
that's not really telling us any support or not weakening either the claim that the um these plants are ultimately using
these acids to not only create channels for continued growth but also to release phosphates to provide the vitam nutrient
phosphorus so this really doesn't weaken it doesn't support either um it's it's for the most part unrelated so we can
get rid of a based on that so that would fit into sort of um the neutral or unrelated category for the most part if
we take a look at B we have though BT and BM both secrete citric and malic acids each species produces these acids
in different proportions okay this right here it's not supportive of our hypothesis it's not weakening our
hypothesis it's just neutral and unrelated so fits in into pretty much the same bucket as answer Choice a would
there okay if we take a look at option C now we have the roots of BT and BM carve new entry points into rocks even when
cracks in the surface are readily available all right well if we go back up to our hypothesis okay we know that
if these roots are or these cracks are already available readily available we would expect that if they didn't need
the phosphorus they would just grow into the cracks okay because they wouldn't need to ultimately create these new
cracks which is more costly and requires more energy from the actual plant itself to make these new cracks okay so this is
actually supportive of that hypothesis right because if they were to just take the cracks that were already entered not
create new ones then that would support the idea that or that would weaken the hypothesis and support the idea that
they don't actually need the phosphorus but because they are actively carving new entry points into the Rocks even
though the cracks are already available and they're not just growing into the cracks this supports the idea that they
would need to do that in order to get the phosphorus okay so we know our answer there is going to have to be C we
can take a look at d as well because uh let's see what wrong Choice bucket that falls into so I can teach that we have
BT and BM Thrive even when transferred to the surfaces of rocks that do not contain phosphates well if they're
thriving on rocks that don't contain phosphates that would weaken our hypothesis that BT and BM need to get
phosphorus from these rocks by carving in these new entry points okay so if they're thriving without phosphorus then
that would weaken that hypothesis okay so D would fall into the bucket of being the opposite of what we need so the
opposite in this example would be something that weakens our hypothesis now now if our question was What would
most directly weaken the hypothesis then D would be right and C would actually be the opposite okay so I wanted to point
out those wrong answer Choice Types on questions that are asking you to support or weaken a hypothesis or a claim here's
one of the biggest things you need to watch out for on the digital sat reading section when asked to logically complete
text so the way I would approach question 17 is I'd start by taking a look at the prompt in this case we just
got Which choice logically completes the text then I'll go back up and I'll start reading so we have herbivorous sarod
dinosaurs could grow more than 100t long and weigh up to 80 tons and some researchers have attributed the
evolution of sods to such massive size as to increased plant production resulting from high levels of
atmospheric carbon dioxide during the mesic ERA this case we have researchers attributing something so I'll mark that
with an A so any sort of hypothesis claim attribution along those lines or speculation I will Mark with a letter in
this case a for attribution and I'll keep reading however there is no evidence of significant spikes in carbon
dioxide levels coinciding with relevant periods and S OD Evolution such as when the first large sods appear when several
sorod lineages underwent further Evolution toward gigantism or when sods reached their maximum known sizes
suggesting that blank okay well as you can see we have a contrast here and then we go on to describe that there's no
evidence for the attribution so I got no evidence I'm underline that I'll draw the arrow back to attributions so we
know that there's no evidence for that all right suggesting that what we have option A fluctuations in atmospheric
carbon dioxide affected different sorod lineages differently well once again we have no evidence for fluctuations in
atmospheric carbon dioxide okay so no evidence for these fluctuations so I can get rid of a we can go move on to B we
have the evolution of larger body sizes and sods did not depend on increased atmospheric carbon dioxide okay we know
that in our attribution we thought that it did depend or at least coincide with this increase increased plant production
resulting from high levels atmospheric carbon dioxide but we know there's no evidence of significant spikes in carbon
dioxide levels okay so we would then that the evolution of larger body sizes did not depend on increased atmospheric
carbon dioxide okay so there's evidence to support that so we can go ahead and Mark B is our answer I'm going to
quickly go over C and D as well and we can discuss which box of wrong answer choice they fit into because there are
common types of wrong answer choices on the digital sat reading section so here we have C atmospheric carbon dioxide was
higher when the largest known sods lived than when it was than it was when the first Sor pods appeared well once again
if we go back up we state that there's no evidence of significant spikes in carbon dioxide levels coinciding with
relevant periods in sarod evolution okay so there is no support for that Spike okay so we can get rid of this based on
this part here the atmospheric carbon dioxide was higher when the largest known sods lived okay we don't know that
so we can get rid of C if we take a look at D now we have sods probably would not have evolved to such immense sizes if
atmospheric carbon dioxide had been even slightly higher so there's a few things wrong with this okay for one this isn't
even supportive of the high hypothesis or the attribution okay so it's not even supportive of that we know the
attribution is wrong okay we also know that we never state that sods could not have evolved to such immense size as if
atmospheric carbon dioxide had been even slightly higher so there's no evidence for this okay so we can go and get rid
of it based on the fact that there just is no evidence okay so our answer there would have to be B so what I want you to
take away from this is a couple things for one on this question type which is a fairly common one which Choice logically
completes the text I want you to Mark any claims hypothesis attributions conclusions things along those lines I
want you to mark them with their coinciding letter um or underline them whatever marking use is up to you okay
the next thing is you want to be deliberate about going back to the text okay because often times you saw as we
went through these answer choices you'll need to go back to see what logically makes sense and that's especially true
for science texts like this okay this is ultimately a science passage okay for science-based passages you will very
often you to go back to the text okay find what evidence there is to support what's coming after or what's completing
the text here's a second example of how I recommend approaching questions that ask you to logically complete text on
the digital sat reading section so I'll illustrate this question 18 in documents called judicial opinions judges explain
the reasoning behind their legal rulings and in those explanations they sometimes cite and discuss historical and
contemporary philosophers legal scholar and philosopher Anita L Allen argues that while judges are naturally inclined
to mention philosophers whose views align with their own positions the strongest judicial opinions consider and
rebut potential objections I'm going to mark this with a claim okay it says she's arguing this so you could mark it
with an a you can mark it with a c I guess in this case I'll mark it with an a for aru this is her argument okay
discussing philosophers who views conflict with the judge's views could therefore what okay so we have
discussing philosophers views who conflict with judges views could okay well we know that her argument is that
while judges are naturally inclined to mention philosophers whose views aligned with their own positions the strongest
judicial opinions consider and rebut potential objections okay so discussing philosophers whose views conflict with
judge's views she would you would therefore strengthen their arguments okay so we have option A allow judges to
craft judicial opinions without needing to consult philosophical works well it's actually the opposite okay it would
force judges to craft judicial opinions with instead of without with needing to consult philosophical work since they
would have to consult works that they're not familiar with or ones that they disagree with so they would need to
consult them so we can get rid of a okay a essentially has sort of the incorrect relationship in terms of with versus
without okay let's go and take a look at B now we have help judges improve Pro the arguments that they put forward in
their judicial opinions well we know that that is her argument her argument is that the strongest judicial opinions
consider and rebut potential objections therefore discussing philosophers whose views conflict with judge's views could
therefore improve the arguments that they put forward in their judicial opinions okay so this is ultimately
going in line with what she is arguing okay so our answer there would have to be B I'm going to take a look at C and D
as well so we can teach a little bit based on those we have C make judicial opinions more comprehensible to readers
without legal or philosophical training well we never discuss legal or philosophical training or the
comprehensibility to readers that's not the goal of this the goal isn't um in discussing with conflicting philosophers
views the goal isn't to make it more comprehensible to the readers the goal is to make it a stronger argument okay
so this would be trying to achieve a separate goal or a different goal from what is actually stated by Anita L Allen
okay so this would be if you were not um if you misinterpreted basically the argument that she's trying to make or
the goal behind this if we look at D we have bring judicial opinions in line with views that are broadly held among
philosophers well for one thing philosophers hold many different views okay so that wouldn't really make a ton
of sense but also the goal isn't to bring the judicial opinions in line with the views of philosophers the goal is
just to strengthen the argument this all goes back to understanding and identifying Anita L Allen's argument
okay her argument once again I will go back up is that well judges are naturally inclined to di menion
philosopher whose views align with their own positions the strongest judicial opinions consider and reut potential
objections and then when we go on we know that we're specifically looking at and I'm going to underline this again
we're specifically looking at this section the strongest judicial opinions consider and rebut potential objections
we know we're looking specifically at that because we state that disgusting philosophers who views conflict with
judges views could therefore do what okay and since we're talking about how to um since we're talking
about views that conflict with the judges okay that's the potential objections that I underlined here so it
would have to be that it makes the judicial opinion stronger in order to continue this idea okay so answer there
has to be be as far as what I want you to take away from this a couple things I talked about this in the last question I
went over that dealt with completing the text but you want to make sure that you're marking any arguments claims
hypotheses conclusions with a letter or some sort of other marking so that you know how to go back to that in the text
the other thing is if you can I talked about this in a question type that was different than completing the text but
but you want to make sure you're understanding where to go back to okay so in this case you saw that we really
really focused in on the strongest judicial opinions consider and rebut potential objections okay and the reason
is that that is what is directly discussed in this next part discussing philosophers whose views conflict with
judges views that is the potential objections so as you can see most of that text pretty much the whole first
half were really not very concerned with so generally on the SAT reading section and this is not specific just to this
question type if you can limit where you're going back to in the text to just where it is necessary in order to answer
the question correctly that will help you there will be times when you need to you know go through more of the text or
maybe even all of the text when going through an answer Choice um and that's okay that does happen but on certain
questions you can keep the scope of text that you need to refer back to more limited and that will help you save some
time here's how I recommend you approach questions on the digital sat reading section that asks you to fill in a
quotation to effectively illustrate some sort of claim okay so the first thing that I would do if I had just scrolled
down to question 12 is I would identify in this case I need to effectively illustrate a claim I would underline the
fact that it's a claim okay so I'm going to mark my claim as I do this readr so we have o Pioneers is a 1913 novel by
will a Cather in the novel Cather portrays Alexandra bergson as having a deep emotional connection to her natural
surroundings okay the claim here is that bergson has a deep emotional connection to our natural surroundings that's the
claim okay so now we just need to go a b c find one that supports that so the
question that you need to ask yourself after you read through each answer Choice here is does this support the
claim okay or does this illustrate the claim rather okay illustrate does it illustrate the claim so let's go and
start with a she had never she had never known before how much the country meant to her okay so this is illustrating that
she cares for the country the trapping of the insects down in the long grass had been like the sweetest music she had
felt as if her heart were hiding down there okay so it felt as if her heart were hiding down there somewhere with
the quail and the Plover and all the little wild things that CED or buzzed in the sun okay so obviously she has an
emotional connection here feels her heart is hiding down there under the long shaggy ridges she felt the future
stirring so clear that she has a deep emotional connection to Nature from answer Choice a okay so obviously that
is illustrating the claim I'll quickly go over b c and d as well because it can be helpful to understand why wrong anes
are wrong so we have B Alexandra talked about talked to the men about their crops and to the women about their
poultry she spent a whole day with one young farmer who had been away at school who was experimenting with a new kind of
clover head she learned a great deal so some people might look at be and say okay it talks a ton about nature that
must be the answer but it's not because we have to keep in mind the entirety of our claim if we scroll up we see our
claim is that she has a deep emotional connection to her natural surroundings okay answer chice B while it talks about
nature it does not show or illustrate that she has a deep emotional connection to Nature it is just talking about her
um sort of learning more about nature okay but not showing she has a deep emotional connection to it I can learn
about football that doesn't mean I have a deep emotional connection to football okay so that's that's why B would have
to be wrong there okay so understand that just because we talk about one of the topics mentioned in the claim does
not mean we are illustrating the claim if you look at C we have Alexander drove off alone the rattle of her wagon was
lost in the howling of the wind but her Lantern held firmly between her feet made a moving point of light along the
highway going deeper and deeper into the dark country okay once again even though we are talking about going into the dark
country which can be pertained or could be you know thought of as going deeper into possibly nature if you were to
associate country with nature which is a pretty fair Association it does not support once
again the fact that she has a deep emotional connection to her natural surroundings okay so you have to make
sure that you are illustrating the entirety of the claim and not just talking about one of the topics of the
claim which would be nature in this case if you look at D we have it was Alexander who read the papers and
followed the markets and who learned by the mistakes of their neighbors it was Alexandra who could always tell you
about what it had cost to fatten each steer and who could guess the weight of a hog before it went on the scale closer
than John bergson her father himself okay so a couple things I want to point on on this one okay first off at the end
here when we talk about how she could guess the weight of a hog before it went on the scales closer than her father
himself that's probably indicating that she grew up close to Nature close probably on a farm okay since she's able
to guess the weight of a hog better than her father is so presumably she has done a lot of work on a farm so that's kind
of what that is indicating but I could once again kind of the same similar example to football right if I had
worked on a farm for a long time that does not necessarily mean I have a deep emotional connection to Nature it just
means I've worked on a farm for a long time and probably know how much a hog weighs okay so you cannot associate that
that does not illustrate having a deep emotional connection with nature okay so that's the problem with d so I think the
key thing I want you to take away from um this question and sort of this example is number one the way you
approach this identify what you need okay in this case you have to first identify the claims we identify the
claim in this case we need to illustrate that claim so we go through a b c and d okay find which one illustrates that and
recognize that we need to actually illustrate it we cannot just mention or talk about the topic okay in this case
it was nature but it could be another topic it's not enough just to discuss the topic or put the character in a
setting where the topic is you have to actually illustrate the entirety of the claim here's a second example of a
question where you're asked to provide a quotation to affect itively illustrate a claim okay so this is very similar to
the last question in this case we are dealing with a poem however there's also one other thing I want to point out with
this question which is why I wanted to include it here so we have question 12 to you is an 1856 poem by Walt Whitman
and the poem Whitman suggests that readers whom he addresses directly have not fully understood themselves writing
all right well first let's go and identify the claim okay the claim is that the readers who he's addressing
directly have not fully understood themselves guys that's the claim they have not fully understood themselves
okay now we got to keep in mind this is a poent so let's go and go through our options we also need to understand that
he's writing this poem directly to the reader it's called to you okay so we need to understand the
perspective of the reader the perspective is he's addressing them directly okay and that's stated up here
that he's addressing them directly so perspective is something you need to pay attention to on the SAT reading and
writing section so just recognize that if you come across a poem especially you're going to want to be able to
recognize perspective um narratives as well but in particular poems okay so let's go ahead and look through our
options we have option A you have not known what you are you have slumbered upon yourself all your life your eyelids
have been the same as closed most of the time okay you have not known what you are you have slumbered upon yourself
okay sleep is sort of a signifier for not fully understanding yourself but if you're looking for something even more
explicit you have this first part before the comma you have not known what you are you do not understand yourself okay
is essentially what he is saying and when you take into account perspective when he says you have not known what you
are he is saying you have not fully understood yourself okay so a is perfect there let's goad
and talk about b c and d as well okay so we have option b these immense Meadows these interminable Rivers you are
immense and interminable as they well him calling the reader in that case is us because we are the reader here
immense is not stating that we have not fully understood ourselves so we can get rid of B that is not illustrating the
claim if we take a look at C I should have made my way straight to you long ago I should have blabbed nothing but
you I should have chanted nothing but you once again that is not showing that or is not illustrating that we have not
fully understood ourselves so we can get rid of C okay now we get into D and D is where perspective really comes into play
okay option D States I will leave all and come and make hymns of you none has understood you but I understand you so
what many people will do here is they will see none has understood you and they will translate that into thinking
that D has to be the answer because if we scroll up the claim is that Whitman suggesting to the readers who he's
addressing directly that they have not fully understood themselves but this is where perspective comes into play if I
say to you my viewer right now no one has understood you would you interpret that to mean that you yourself have not
understood you probably not okay if someone says to me no one has understood you Hayden I would not interpret that to
mean that I myself have not understood myself okay so this is where perspective comes into play because he is addressing
us directly we need to to recognize and interpret this as no one has understood you that is not the same as saying that
you have not understood yourself because of the perspective here okay so that is the problem with answer Choice D okay D
is stating I will leave all and come make the hymns of you none is understood you but I understand you okay so
ultimately we can get rid of D we see our answer has to be answer Choice a here's how I recommend you approach
questions on the digital sat reading section that ask you to use data from either a table graph or any sort to
support or weaken any sort of claim or hypothesis or conclusion okay so I'm going to illustrate this with question
number 15 the way I would start is I'd start by reading through the passage so I have Alicia Monte cosos Navaro
Isabelle stoer and Rosio Perez Bales recently examined several plots within a diverse plant community in southeast
Spain the researchers calculated that if individual plants were randomly distributed on this particular landscape
only about 15% would be with other plants and patches of vegetation so one thing that will jump out to me here is
the fact that it's randomly distributed okay anytime that I see something's randomly distributed I'm usually going
to pay attention to it um that goes for the reading section as well as the math section actually um but we'll keep
reading they counted the number of juvenile plants of five species growing in patches of vegetation and the number
growing alone on Barr and compare those numbers to what would be expected if the plants were randomly distributed okay
which we obviously have up there based on these results they claim that plants of these species that grow in close
proximity to other plants gain an advantage at an early developmental stage so here we have a claim okay
anytime we have a claim hypothesis conclusion anything along those lines I will always mark it okay because that
makes it easier for me to come back and find it later so which Choice best describes data from the table that
supports the claim so we're looking to support this claim if we take a look at the table now and that is what I will do
okay before going to the answer choices I will actually go back to the table now I will note that this is a case where it
can be somewhat of a personal preference for me personally I would prefer to go back to the table find what data is
supporting this claim and then look through the answer choices for some people they may want to go straight to
the answer choices I would recommend that you go to the claim or go from the after reading the claim after reading
the prompt going to the table I just find that it makes it easier to avoid getting misled by some of the an choices
but um you know you can kind of make your own decision there so let's go ahead and go through this we've got to
support the claim that species that grow in close proximity gain an advantage at an early developmental stage we have
juvenile plants found growing on bare ground and then patches vegetation for five species we got the five species got
the number found in be ground found in patches vegetation we we got the total we got the percent found in patches of
vegetation now one thing that we need to keep in mind here is that if they were randomly distributed we'd expect that
15% would be with other plants in patches of vegetation so we would expect that the percent found in patches of
vegetation would be 15% okay so 15% and that's for individual plant so it doesn't give a a name on the species so
I would just expect 50% in all of these then 15% as we can see we don't have that we' have above 50% all of them
which is more than three times what would be expected okay so that's really the evidence I'm looking for is pretty
much stating um pretty much all of this column of this table um is obviously more than three times what was expected
so let's go down and look at our options okay so we have option A for all five species less than 75% of juvenile plants
were growing in patches of vegetation well that is not supporting the claim okay so we can get rid of a we need to
focus on the fact that it's three times what would be expected compared to random distribution we got B the species
with the greatest number of juvenile plants growing was H sto Stow okay we don't really care um about one
particular species versus the other okay we used five species if we look back up at our text but we're not really
concerned with a comparison of the species Okay so we've got option C we got for T Li lianes and T morido the
percentage of juvenile plants growing in patches of vegetation was less than what would be expected If plants were
randomly distributed well we actually see that it's more than what would be expected If plants were randomly
distributed so this would fall into the bucket of wrong answer choices that is um the incorrect um I guess in this case
it's a a misinterpretation okay because it's actually stating it's really just misinterpreting the data it's stating
that it's a less than what would be expected but it's actually more okay so this would just be a misinterpretation
of the data we've got option D now for each species the percentage of juvenile plants growing in patches of vegetation
was substantially higher than what would be expected if the plants were randomly distributed okay we see that that's true
according to the data okay as you can see by going back to the table first and finding what data from the table would
support that claim okay I was able to have an idea of what I'm looking for before going into the answer choices
here's a second example of how I recommend that you approach questions on the digital sat reading section that ask
you to use data for some reason whether that's to support or weaken some sort of claim or in this case to complete an
example so first thing I would take a look at is the prompt okay we've already gone over that so from here instead of
going straight to the data I'm going to go ahead and go to where I have my passage so we have some researchers
studying indigenous actors and filmmakers in the United States have turned their attention to the early days
of Cinema particularly the 1910s and 1920s when people like James Young Deere Dark Cloud Edwin Kare lilan St seir
known professionally as Redwing were involved in one way or another with numerous films in fact so many films and
Associated records of this era have been lost that counts of those four figures outputs should be taken as bare minimums
rather than totals it's entirely possible for example that okay we have for example so we need to discuss what
we're getting an example of well ultimately we state that um so many films and Associated records have been
lost that counts for these figures outputs should be taken as bare minimums rather than to rather than totals it's
entirely possible for example that blank okay so we'd be looking to discuss how um it looks like in our table we've got
number of films known and commonly credited and then we have years active in the individual credited credited film
output keep in mind since this is the credited film output we've discussed how that's a bare minimum not a total and
then we're stating it's entirely possible okay since we're saying it's possible that um these are bare since
these are bare minimums it would be possible that our numbers would be higher than what's in this table then
okay so um which Choice effectively uses data to complete the example okay in this case like on the last question I
prefer to go back to the T data table okay and try to figure out how I can use that to in this case I need to complete
the example in the past example it was supported claim so to complete the example it's much more difficult to
actually come down with an idea of what you're looking for but in this case um looks like we're just going to be
looking for an example that provides greater numbers than what's in here for all these for all these uh these rows
because what's in these rows is really just to be bare minimums is what we're told not the actual total
so we've got option A Dark Cloud acted in significantly fewer films than did St lilan Lilian St Seer Who is credited
with 66 performances well that's not providing an example okay keep in mind we need to provide that example because
that's what we're told we've got B Edwin CES 47 credit acting roles include only films made after 1934 well if we go up
we've got years active 1912 to 1934 for Edwin K uh his 47 acting roles include only films after 1934 well we got 47
acting rol here we see that that's from 1912 to 1934 so B is incorrect according to the data so we can get rid of that we
can go down we can look at option C we have Lilian Saint SE acted in far more than 66 films and Edwin K directed more
than 58 so Lilian Saint SI we can find where she is we have got 66 here okay this is the amount that she's credited
for we know that we're looking for that being a bare minimum and that she actually did more than that so this
makes sense next we have Edwin K directed more than 58 we see Edwin K uh was credited as the director for 58 once
again we're stating that he did more than that which is in line with an example that these are bare minimums and
not totals okay so C looks perfect we'll take a quick look as at d as well D states that James Young Deere actually
directed 33 films and acted in only 10 okay we can find James Young Deere we see that he's credited with 33 okay and
he's credited as the writer for uh 10 so 33 actor and writer for 10 uh so in this case it's stating that he actually
directed 33 films oh okay he stayed as the director for 35 so that'd be less than so that is not an example so that
actually be the opposite of what we are looking for so you can put that in the bucket of an opposite um for the wrong
answer Choice okay so answer there would have to be answer Choice C okay so the key thing I want you to take away from
these last two examples so you have a question like this where you're asked to use data for you know something or
another on the SAT reading section that I recommend that you would approach it would be you start by taking a look at
the prompt from there go to the passage once you're done with the passage figure out what you need from the data go back
to the data once you're done going back to the data have an idea of what you're looking for in your answer choice to
either support weaken whatever you need then then go to your answer choices in this section of the course you'll see me
solve over 150 practice problems from the released digital SAT practice test for each question I try to explain the
strategy I'm using along with any tips tricks or advice I have for similar questions I'm teaching these Concepts
through released practice questions because it allows you to not only learn the math required to be able to solve
these questions but also learn how to best apply them to the digital sat here's how to answer this sat math
question in under 30 seconds the question States the line graph shows the percent of cars for sale at a used car
lot on a given day by model year for what model year is the percent of cars for sale the smallest well we see on our
y- AIS we have the percent of cars for sale and we just have to find where that's the smallest we see that that's
in the year 2014 so our answer is going to be answer Choice C here's how to answer this probability question on the
SAT question two states for a particular machine that produces beads 29 out of every 100 beads it produces have a
defect a bead produced by the machine will be selected at random what is the probability of selecting a bead that has
a defect in this case we are looking for those that have a defect which we know is 29 out of every 100 so we know that
probability of that must be in Choice C 29 out of 100 here's how to answer this question about intersecting lines on the
SAT question three states in the figure line M is parallel to line n and line T intersects both lines what is the value
of x well since M and N are parallel line T is intersecting them we know that X is going to be the same as the angle X
I just drew next to that angle 33 now we also know that a semicircle has 180° in it so all we have to do is 180° - 33°
and that will give us our answer of 147° as the angle X so our answer is D here's how to find the Y intercept of this
graph on the SAT the question States what is the Y intercept of the graph shown all you got to do is find when
we're crossing that y AIS where X is zero and we see that that is at 8 so our answer there is going to be 08 here's
how to solve this sat math question in under 60 seconds the question States the total cost F ofx in dollar s lease a car
for 36 months from a particular car dealership is given by F ofx equal 36x plus 1,000 where X is the monthly
payment in dollars what is the total cost to lease a car when the monthly payment is 400 we know the monthly
payments are represented by X so we can go and substitute 400 in for x and we will have 36 * 400 + 1,000 and that will
end up giving us our answer of $15,400 which is answer Choice C here's how to solve this question about
perimeters on the SAT question Six States each side of a square has a length of 45 what is the perimeter of a
square well we know squares sides are all the same so the perimeter will just be four times the side length which we
know is 45 we can go ahead and put 4 * 45 in our calculator or you can just do it in your head and you're going to get
180 for your answer as the perimeter of the square here's how to solve this sat math question that deals with factoring
question seven states what is the positive solution to the given equation in order to solve this we need to
ultimately get it set equal to zero so let's go ahead and do that by multiplying both sides by x + 6 once we
do that we have x * x + 6 well also go ahead and subtract 55 from each side so we can set it equal to zero and now we
have our equation so let's go ahead and distribute this x to this other X to get x^2 and then also plus 6X so now we have
x^2 + 6x - 55 is equal to zero now let's go and Factor so I'm looking for factors of 55 that will sum to have positive six
so when I do that I can think we've got 11 and five um I need to keep it positive so I'm going to have to have x
+ 11 and I would have to have x minus 5 now we Factor we have to keep in mind that we can't just pick either one we
need to have the positive solution to the given equation so we know that x + 11 will ultimately mean that X could
equal -1 but we can't choose that cuz that's negative we need to have x = 5 so our answer there would be five here's
how to translate this word problem into an equation and solve it on the SAT question 8 States an object travels at a
constant speed of 12 cm/ second at the speed what is the time in seconds that it will take for the object to travel
108 CM well this is pretty easy the distance that you're traveling is 108 CM you want to know how long it's going to
take you you are traveling at 12 cm/ second okay you're multiplying by your time in seconds okay we'll have t
represented as time in order to solve for T then all you got to do is divide 108 by 12 to get your answer when you do
that you're going to end up with your answer of nine which is the answer Choice a here's how to solve this
question about comparing the mean of two data sets on the SAT question n States the list gives the values in data sets X
and Y which statement correctly compares the mean of data set x with the mean of data set y well let's go and find the
means of both we'll start with data set X so the mean is going to be the sum of these numbers divided by four so 5 + 9 +
9 + 13 now I see I have these same numbers in data set y now I also have a 27 addline to data set y now since we've
got the same four numbers in data set X as in y and then we are just adding in 27 we know 27 has to be greater than
whatever the mean is in data set X because the maximum value in data set X is 13 and 27 is higher than that so it's
going to have to bring that mean up therefore we know that data set y has to have a larger mean than data set X
without even have to calculate the means just by looking at this so we know our answer there has to be B if you want to
calculate the means for this you can but you could also just recognize that 27 is larger than the maximum data set X other
than that they're the same therefore data set y has to be a larger mean here's how to solve this sat math
question in under 60 seconds question 10 states a rocket contained 467,000 kg of propellant before launch exactly 21
seconds after launch 36215 kg of the propellant remained on average approximately how much
propellent in kilograms did the rocket burn each second after launch while our starting amount of propellent is 467,000
we then have to subtract how much propellant remained and then we have to divide all of that by the amount of
seconds that this took place which is 21 seconds once we put that into our calculator we're going to end up with
the answer Choice a and that'll give us exactly or approximately how much propellent in kilograms the rocket
burned each second after launch here's how to use ratios to move faster on the SAT Math section question 11 states if
4x + 2 = 12 what is the value of 16x + 8 whenever I see a question like this I'm always looking for proportions I see 4x
+ 2 If I multiply that by 4 I get 16x + 8 so all I got to do is multiply 12 by 4 12 * 4 is going to equal 48 So my answer
is 48 my answer there is B this way I don't have to solve for so I get it done faster here's how to interpret a common
situation on the SAT Math section question 12 States an object is kicked from a platform the equation h 4.9t plus
7 t plus 9 represents the situation where H is the height of the object above the ground in meters T seconds
after it is kicked which number represents the height and meters from which the object was kicked okay a
common question on the SAT deals with something falling from some certain height whether it's thrown off kicked
off launched off things like that and the way that it's usually represented is in an equation like this in this casee
we're asked which number represents the height from which the object was kicked well the height at which it is kicked is
when it time is at zero right it it's only kicked once the time is zero so that means T would be zero which makes
this zero which makes that zero which means that nine is the height when it is first kicked so our answer there has to
be D here's the type of question where you should use Desmos on the digital sat question 13 states that F ofx equal 4x^2
- 50x + 126 the given equation defines the function f for what value of x does f ofx its minimum if I saw a question on
like like this on the new digital sat I would use Desmos for it 100% I would just check where the minimum is so I'll
go and show you how you would do that all you got to do pull up Desmos you can do this on the digital sat it's built
into the college boards Blue Book so you put in the equation you look for where the minimum is the minimum is at 6.25
for the x value of the minimum so your answer there would be 6.25 so this is a great example of the type of question
where it really does make sense to use Desmos on the new digital sat here's how to set up and solve the system of
inequalities question on the SAT question 14 States a small business owner budgets $2,200 to purchase candles
the owner must purchase a minimum of 200 candles to maintain the discounted pricing if the owner pays
$4.90 per candle to purchase small candles and 1160 per candle to purchase large candles okay I'm using S for small
candles I'll use l for large candles what is the maximum number of large candles the owner can purchase to stay
within the budget maintain the discount pricing so we only have two candle sizes so we can go ahead and determine the
total number of candles would be L plus S I want to quickly point something out you saw as I read through this I was
writing out the system of inequalities as I go if you encounter a question on the SAT Math section that is three lines
or longer it is most likely going to end up being a question that involves either system of inequalities two equations
that you need to set up um possibly something to do with converting units something along those lines but either
way my general recommendation is if a question is three lines are longer on the SAT Math section you try to write
down units variables and obviously like the code efficients in front of certain units um any sort of constants things
like that basically you want to start writing your equation as you read through the word problem because
otherwise if I hadn't written down these two inequalities I would have to go back and do a second read through so this is
a strategy that I use and that I recommend you use to save time that being said let's go ahead and solve for
the number of large candles one thing I want to point out here is you'll notice I'm solving for L right away not s
that's because I don't give about S I don't care about s at all right we don't need s we just need l so that's all
we're going to focus on solving okay so I'm going to go ahead and subtract uh I'm sorry we're going to subtract L from
each side we want to isolate s and the reason why is we want to substitute in for S something with L okay so let's go
ahead and get S by subtracting L from both sides we get 200us L is going to be less than or equal to S now we can go
and substitute in okay so let's go ahead and substitute that in for S okay so we got 4.9 * s which we know we can
represent as 200 minus L okay and keep in mind that we still have a plus 11.6 L right here so let's go and distribute
the 4.9 to the negative L into the 200 4.9 * 200 is going to give us 980 okay so equals 980 then we're going to
have - 4.9 L and plus 11.6 L which will give us plus 6.7 l in total okay because 11.6 L minus 4.9 L gives us that plus
6.7 L now that all is still going to be 2200 over there we'll subtract 980 from both sides minus 980 that's going to end
up leaving us with 1220 20 is going to be greater than or equal to 6.7 L okay from there we would divide both sides by
6 . 7 so we'll go ahead and do that divide both sides by 6.7 okay 1220 ID 6.7 go ahead and put that in my
calculator that's going to be 18209 okay 182 point I'll just call it 0.1 okay
it's 09 all right now we have to see that L has to be less than or equal to that okay so in order to be less than
1821 we would go to 182 we can't have 0.1 of something okay so our answer there in this case we can't because we
can't 0 one of a candle right so our answer there would be 182 so we go ahead and write that down and we'll Circle
that so 182 there's our answer here's how to solve this sat math question in under 30 seconds question 15 states in
the linear function f f of 0 is equal to 8 and F of 1 is equal to 12 which equation defines F immediately I see I
have that F of 0 is equal to 8 which means that my Y intercept is 8 I see all of these are in slope intercept form and
I see The Intercept of c and b is not eight so I can get rid of them next thing I see is the difference between a
and d is the slope if I look at my slope I'm going over one and I'm going up by four so my slope is four So my answer
answer there has to be answer Choice D here's how to interpret this SAT Math problem question 16 states that the
function f of w is equal to 6 W ^2 gives the area in the area of a rectangle in square feet if its width is W feet and
its length is six times its width which of the following is the best interpretation of f of 14 is equal to
1,176 all right well ultimately this function is giving us our area we know that W represents our width so F of 14
means that our width is 14 ft and then that 1,176 means that when our width is 14 ft our area of our rectangle is 1,176
Ft that's answer Choice a so a is our correct answer there here's how to answer this SAT Math problem about Arc
lengths by using ratios and proportions question 17 states that the circle shown has Center o circumference 144 pi and
diameters PR and Qs the length of Arc PS is twice the length of Arc PQ so we'll call Arc pqx and the length of Ark PS we
know is twice that so we'll call that 2x I'll go ahead and Mark those lengths here okay next thing we are asked is
what is the length of Arc QR well Arc QR is going to be the same length as Arc PS so I'm going to go ahead and focus on
solving for PS just because it's easier for me to show on this video so if we go ahead and draw this we see that it's X
plus 2X so that's going to be 3x we also know our circumference is 144 Pi if our circumference is 144 Pi our
circumference is that whole line around the circle right it's all of this that line right there okay so our
circumference is 144 4 Pi then that semicircle right that semi Arc semi Arc is going to be 72 Pi okay so then we
know that 72 Pi is equal to 3x right because it's the sum of that 2X and that X therefore you would know that PS which
is the same as QR okay is 2/3 2/3 of that okay so it' just be 72 Pi just be 72 Pi * 2/3 okay and when you put that
in your calculator or you can just do it in your head you're going to end up with 48 pi as the value for Q to R you could
have also it by doing that 72 Pi is equal to 3x okay and then solving for x and then taking it in and multiplying it
by two but easier ways just to recognize that hey this is a ratio right it's 2/3 2/3 * 72 Pi gets you 48 Pi it's a lot
easier than going through and solving for x so I wanted to put the X down there just so you guys could see and
understand sort of how it breaks down but ultimately it's a lot better if you can just recognize hey this is a ratio
we've got half of this whole circumference is 72 Pi we are taking 2/3 of that to get Arc of QR so answer there
is B here's a couple tips for the SAT Math section to help you be more efficient I'm going to illustrate them
with question 18 question 18 states a company that provides whe watching tours takes groups of 21 people at a time the
company's revenue is $80 per adult so I'm going to represent that as 80a and $60 per child which I'll represent as 60
* C if the company's revenue for one group consisting of adults and children was
$1,440 okay so that's going to be the sum of these the value of the number of adults time the cost per adult plus
number of kids times cost per kid how many people in the group were children well we know that consists of adults and
children so we can represent that as A+ c as you can see I did one read through and I have both my equations so that's
tip number one here as you read through an SAT Math problem that is three or more lines as you can see in this case
it was six that's why I knew that I wanted to use this sort of this sort of tip or trick anytime you've got an SAT
Math problem longer than three lines try to write out the equation or the system of equations as you read through that
way you save time by not having to read do a read through right right afterwards to find your variables and things like
that okay that being said let's go ahead and keep talking because there's more tips to come here now keep in mind we
are asked to solve for how many people in the group were children so you could go through and you could solve for a
first and then get to C but you shouldn't do that you should go ahead and solve for C first you want the most
direct path to your answer on the SAT Math section because it's a timed exam and you want to be efficient so we're
going straight for C we're not we don't want to get a we don't need it so we won't we just don't want to even see it
all right so here's what we're going to do we're going to substitute in a value with C for this a value there the way we
do that is by subtracting C from both sides to get 21- C is equal to a now we go ahead and sub substitute in okay so
it will be 80 * 21 - C + 60 C is equal to 14 we go ahead and distribute our 80 to our 21 and to our C 80 * 21 is going
to be 1680 and then we are also going to have Min - 80 C + 60 C is going to equal 14 now we want to start isolating our C
so - 80 C and plus 60 C is going to leave us with -20 C okay and we're also going to go ahead and subtract 1680 from
both sides okay subtract 1680 from both sides this is going to leave us with 240 or I guess -240 is equal to -20 C
now from here we're going to go ahead and divide both sides by -20 -240 ID -20 is going to leave you with your answer
of C is 12 so our answer there will be answer Choice C because we have 12 children and as you can see by solving
for the number of children first we don't have to go back through and solve for the number of adults we never have
to know the number of adults if you wanted to go back through and see obviously you could just put in the
number 12 there for for C but uh it's not necessary you don't need to know the number of adults so don't care about it
don't need to focus on it just get the number you need to get to and move on to the next question here's how to find x
and y intercepts quickly when you have an equation in slope intercept form question 19 States the function H is
defined by h x equal 4x + 28 the graph of yal H of X in the XY plane has an X intercept at a and z and a y intercept
at 0 B where A and B are constants what is the value of a + b well in this case there's no way to just get to a plus b
normally if I see something like that that's what I'd like to do in this case you have to actually find both A and B
so in this case let's go and start by finding a we see that a is where our yv value is zero well where our yvalue is 0
we have 4x + 28 is equal to 0 we subtract 28 from both sides and we get -28 is equal to 4X we divide both sides
by 4 -28 over 4 is going to equal -7 as the value of x now let's go ahead and solve for our B value and keep in mind
that X there would equal that a value okay so a is-7 now let's go ahead and solve for what B is equal to okay B is
where our x value is zero so we just put in zero there and we see that we ultimately are going to get 28 okay so
we asked for the value of a plus b so we just do 28 + -7 which is the same as 28 - 7 that's going to leave us with 21 so
our answer there is a here's an example of an SAT math question that's gotten way easier now that the SAT has gone
digital question 20 States one of the factors of 2x CU + 42x 2 + 28x is X plus b where B is a positive constant what is
the smallest possible value of B now keep in mind you need the smallest possible value of B and that's important
here because there's going to be two possible answers but I want to show you why this question is so much easier now
that you have Desmos built into Blue Book on the the digital sat before you would have to factor this out and that
could be a bit difficult and there's a lot of room for when you're doing that but now that you have Desmos in the blue
book app when you're taking the digital sat you can just put it into Desmos now you have to also understand how to work
the problem with Desmos so in this case you know that you need the value X plus b now what that means is that you're
looking specifically in this case at the negative X values or the negative X values on in regards to the x intercept
right so let me go ahead and zoom in here the reason that we're going to the negative section is because it can't be
a positive number because these are ultimately our zeros they're not our values for B okay our zeros here and as
you can see the first negative or the first zero there is at8 okay now that does not mean negative
8 is our answer because it's not okay because you have to keep in mind that we're looking for the value of B and X
plus b and X plus b since it's one of our factors has to be set equal to zero which means that X is actually going to
equal negative B now we know our value for x okay our value for x is ne8 which means that B has to equal positive 8
okay so our answer there will be8 now you really need to make sure that if you are using Desmos which I do recommend
you do you do take close account to the signs of values and you understand how to interpret these graphs because if you
don't understand how to interpret these graphs but you try to use them it's not going to help you so as you saw when I
looked here I had to understand that I'm looking for the value of B okay to get to that I need to understand how a
factor works right the factor has to be set equal to zero and then once I find this value of x I have to remember to
get that back to be so make sure that when you do use Desmos on the digital sat which I do recommend you do cuz
helps a ton and makes you faster less prone to error that you do at least understand how to interpret these graphs
here's what you need to know about questions that ask you about the number of real solutions to a quadratic
equation on the SAT I'm going to illustrate this with question 21 question 21 states in the given system
of equations a is a positive constant the system has exactly one distinct real solution what is the value of a whenever
you have a question asking you about two real solutions one real solution is no real solutions or the number of real
solutions it's basically testing do you know this crucial Rule and that rule is is B ^2 - 4 a c okay now this works when
you have an equation quadratic equation that is set equal to zero okay so a quadratic equation looks like this and
it's got to equal out to zero now I'll show you how we get to there in regards to this question in a second but first I
want to explain this rule so b^2 - 4 a c if this value is greater than zero that means that there are going to be two
real solutions now what if this value is equal to zero in that case there is one real solution and what if this value is
less than 0 well if B ^2 - 4 a c is less than Z then that means that there are going to be no real solutions okay so
zero real solutions okay I guess I should actually Express that as zero because that's the way it is commonly
shown on the is zero real solutions okay with this being said I want to go ahead and go over how we apply this in this
question okay so in order to get our b^2 minus 4 a value like I said we have to set it equal to zero in this case it is
not set equal to zero yet we have to substitute in this - 1 and2 for y first so then we would end up with - 1/2 = x^2
+ 8x + a okay from here I'm going to go ahead and add 1 and a half to each side so that we can get it set equal to zero
so we can use this this rule of b^2 - 4 a c okay so then we have that much plus a plus 1 and2 now what I'm going to do
is I'm actually going to pick essentially a random variable which I'm just going to call we'll use J now I'm
trying to pick one that doesn't sound like a or look like a number let's use uh we're going to use Z okay and I'll
try to make it very differentiated okay I'm gonna let Z equal a plus 1.5 all right so now I'm going to go ahead and
substitute in Z for a plus 1.5 and you'll see why I'm doing this in a moment here okay so now we have our
quadratic equation it's set equal to Z now we can do b^2 minus 4 a c now you may be wondering what's B what's a and
what's C well I'll go and show you okay our a value is whatever coefficient is in front of this x squ since there's no
coefficient in front of it it's one okay so our a value is one our B value is going to be8 it's whatever is in front
of that X okay and our C value is the constant which in this case we're representing a z all right so B is8 so
that's going to be squared 8^ squar is 64 okay so b^2 minus 4 * a our a value is 1 okay so we don't need to show that
okay and then times C which we're representing as Z to represent that a plus 1.5 all right now we know that
there has to be exactly one real solution which means we have to set it equal to zero now it's pretty easy to
solve we're going to go ahead and add 4 Z to each side so we'll have 4 Z is equal to 64 we'll divide both sides by
four to isolate Z so now we have Z all alone we know that Z is equal to 64 over 4 which is going to equal 16 okay so now
Z is 16 well now that we have Z is 16 we can go back up here and we have 16 is equal to a + 1 and A2 I'm going to erase
this so you can kind of see what I'm doing back up here 16 is equal to A+ 1 and A2 I subtract 1 and A2 from each
side and I get 14.5 is equal to a okay so there's what you need to know about the number of Solutions on the SAT Math
section along with this question as an example of how you can apply it here's how to quickly answer this sat math
question by understanding zeros question 22 States f ofx is equal to x + 6 * x + 5 * x - 4 the function f is given which
table of values represents Y is equal to F ofx minus 3 very important thing to here is to recognize is that f ofx is
this equation we have to do that minus 3 there okay so what we can actually call this is I'm just going to scratch this
out I'll call it Y and then I'll just add that minus three at the end it's the same thing all right so now we have our
new equation Y the next thing that we see is that we have to find the table values that represents it the key thing
that I'm looking for here is I want to find where I have a zero in parenthesis which we're going to have when X is
sorry let me write that where you can see it uh we're going to have that where X is at6 because 6 plus 6 is 0 we're
going to have that where X is neg5 because 5 plus 5 is z we'll have that where X is four 4 - 4 is 0 I'm going
look for those X values in my table here I see all of them are in here okay so I know they're all there and any time I
have one of these I'm going to have a yv value of3 because 0 * anything is going to end up being zero so then I just end
up with 0 minus 3 okay as we can see a has to then be incorrect B has to be correct because it has all of these
values of our zeros in this x side of the table and has ne3 for all of them so B is our correct answer here's how to
quickly solve this sat math question by understanding the equation for exponential growth question 23 states
that for the function Q the value of Q of X decreases by 45% for every increase in the value of x by 1 if Q of 0 is
equal to 14 which equation defines Q well Q of 0 being 14 means that our Y intercept where X is0 is going to be 14
which means our initial value is 14 so we can get rid of A and B because their initial values are not 14 next thing we
need to recognize is our growth rate okay or our growth factor we have q ofx decreasing by 45% for every increase in
the value of x by one if we're decreasing by 45% that means our growth factor is 0.55 okay we're not getting
bigger answer Choice D would mean that we are increasing decreasing so that growth factor has to be less than one so
our answer there is C here's a trap to avoid on the SAT Math section question 24 States the graph of yal f ofx + 14 is
shown which equation defines the function f many people will pick answer Choice C on this question because
they'll see the Y intercept is two and pick answer Choice C but that's not correct and the reason why is because
you have to pay close attention to the details on the SAT Math section this question States the graph of y = f ofx +
14 is shown and we're asked to define the function f not the function y not y = FX + 14 so the function f has to be
down it has to have a y Interceptor that is 14 below where it is on this graph so if we go down 14 from two we have to be
at -12 which means our Y intercept has to be -12 and our answer has to be answer Choice a because that's the only
answer Choice with -2 as the Y intercept so on the SAT Math section pay very close attention to details with what
you're asked to answer with and any equations that you're given any equations or functions that you're given
in the context of the question here's how to solve this question about tangents here's how to solve this
question about similar triangles and tangents on the SAT Math section question 25 States the side lengths of
right triangle rst are given triangle rst is similar to triangle uvw where s corresponds to V and T corresponds to w
What is the value of tan of w well the first thing I'm going to do is since I have rst as the triangle and they're
similar the tangent values are also going to the same for the corresponding angle so I'm going to go ahead and find
that W what is it equal to an rst okay so if I've got V and T correspond let's see s corresponds to V all right so s
corresponds to V okay I see that's the middle one that's the middle one and then T corresponds to W okay I see that
that's the last one that's the last one that means that R will correspond to you okay but we've got tan of w okay so
that's going to be T all right so we have to find tan of T okay I can just write that as then tan of T okay it's
the same thing because these are similar triangles going to have the same tan values for the same angle all right so
now what is the value of it well let's go aad and draw out this triangle okay cuz that's just going to make it easier
to visualize we have a right triangle we have uh we've got rst so let's go ahead and just Mark that rst we know T to R is
52 we know s to T is 48 okay and keep in mind this is obviously not drawn to scale okay it's just a quick sketch
because we're only really worried about the actual values not really the the angle measures all right so now we want
to know the value of t of w or tan of T all right well we know that the tan is the opposite over our adjacent okay so
our opposite from T would be 20 and our adjacent would be 48 so that's going to equal 20 over 48 which we can simplify
down and we see we have to because 20 48 is not an answer choice so for simplifying this down we can go ahead
and divide them both into four and that's going to give us 5 over 12 as our answer that'd be answer Choice B here's
how to solve this sat math question that deals with rearranging variables question 26 States one G of paint will
cover 220 Square ft of a surface a room has a total wall area of w Square ft which equation represents the total
amount of paint p in gallons needed to paint the walls of the room twice all right so here's how I ended up with this
equation one quick note you saw I started writing down variables and uh sort of the coefficients in front of
those variables as I read through that's a strategy I recommend that you do anytime that you have an SAT Math word
problem that is three lines or longer okay just cuz helps you avoid having to reread as much so just want to make note
of that that being said let's go and talk about how I got there all right so we have one gallon of paint is going to
cover 220 square feet of the surface okay so we have 220 is the amount of square feet one gallon p is going to
cover okay so this gets us the amount of coverage that we're getting now we know that has to equal the area of the wall
times two because we're going to do it twice right we're going to paint the walls twice okay so now we have our
equation now we see that we need to solve for p so we have to find what P equals now all this question basically
hinges on you setting up this equation correctly initially if you don't set it up correctly initially you're not going
to get to the right answer so you have to make sure that you understand how the units work right because as you can see
here we are ultimately getting to an area by taking the amount of coverage we get per gallon of paint multiplying by
the number of gallons now we get our area we're setting that equal to an area as well so checking if your units match
is a good way to check your check your work as well so I wanted to point that out okay we're ultimately getting area
equals area all right that being said let's go ahead and solve for p now we know that P is going to equal W * 2 all
over 220 because we divide both sides by 220 next thing we'll do is we'll go ahead and simplify okay we can divide 2
by two and 220 by two that's ultimately going to give us if we go and cross both those out we'll end up with 110 in that
denominator so p is equal to W over 110 our answer there will be answer Choice a here's how to solve this difficult sat
math question question 27 States the number a is 110% greater than the number B well that means that a is going to
equal 2.1 * B because it's 110% greater than the number B okay keep in mind pay attention to that that greater there
that means it's going to be 2.1 * B all right the number B is 90% less than 4.7 well another way to say that is the
number B is 10% of 47 okay so that means that b is going to equal 0.1 * 47 which is going to equal 4.7 now we're asked
what is the value of a well this is pretty easy to solve for now okay in order to get a we need to know the value
of B which we now know is 4.7 so we just do 2.1 * 4.7 if we put that into our calculator we will get 9.87 as the value
of a so our answer is 9.87 here's how to answer statistical inference questions on the SAT question one states that
there are 55 students in Spanish Club a sample of Spanish club students was selected at random that's important
whenever you're doing statistical sampling it must be random sampling in order to provide an accurate statistical
inference for you to use later on and as whether they intend to enroll in a new study program of those surveyed 20%
responded they intend to enroll always pay attention to if it's they intend or they not to intend because sometimes
they will put in something that has only two options and they will give you one of those being they do or the other
being they do not and you have to pay attention to what you're given in this case we're given that they do intend to
enroll in the study program based on the survey which of the following is the best estimate of the total number of
Spanish club students who intend to enroll in the study program in this case this question is super straightforward
we have 55 total students were told that of those who responded which was a random sample 20% said they would intend
to enroll were asked for those who would intend to enroll so all we have to do is 55 * 0.2 and that'll give us 11 so our
answer there would be a here's a tip to help you be more efficient on the SAT question two states Jay walks at a speed
of 3 miles per hour and runs at a speed of 5 miles per hour he walks for w hours and runs for R hours for a combined
total of 14 miles which equation represents this situation okay well as you can see I've already got my answer
without having to read through a second time and the reason why is because I wrote down my variables as I read
through as you can see it's a little bit messy because my focus is on reading but I don't have to read through again and
the reason you want to do this is because if you were to read through this word problem without writing anything
down and then you get to the end and it says which equation represents the situation you now have to go back
through you have to look for your numbers you have to look for your variables so what I do when I encounter
a word problem on the SAT and you can usually tell pretty much right off the bat if it's a word problem because it'll
be usually at least three lines or longer in this case it was four lines you want to write down any numbers they
give you and any variables they give you as you go through and you want to try to sort of get it in the equation form that
you're expecting and this comes with a little bit of practice but as you can see once I saw we've got walking at 3
miles per hour right running at 5 miles hour I'm guessing it's going to be a summation to get us distance so I went
ahead and I put the three here the five here and then once I got my variables went ahead and attach them to the appro
appropriate number that I got earlier in the question and then got the equation not having to read through twice so this
is a great way to save time on the SAT and I highly recommend doing it here's how I recommend approaching questions
about Scatter Plots on the SAT question three states the scatter plot shows the relationship between two variables X and
Y a line of best fit is also shown which of the following equations best represents the line of best fit shown
what I do in this situation is I take a quick glance at the answer choices to see what format they're in in this case
I see they're all in slope intercept form which is going to make this question really easy so let's start by
finding our intercept we see our intercept is positive right around three which means we can go and get rid of c
and d because they both have negative y intercepts the next thing I'll take a look at is the slope in this case I see
my slope is positive if I look at answer choices A and B I see only one of them has a positive slope So my answer has to
be answer Choice a here's how to answer this question that deals with y intercepts really quickly on the SAT
question States the graph of yal f ofx is shown in the XY plane what is the value of F of0 Well the value of f of Z
is just the Y intercept so if we take a look at our graph we see our answer is going to be three so our answer is
answer Choice D here's how to answer questions about adding exponents on the SAT question five states which
expression is equivalent to and then we have this multiplication question where m q and z are positive what you need to
understand in order to answer this question correctly is how to add exponents when you have the same base so
to illustrate this let's look at m m ^ 4 * m is equal to M the^ of 5 because it's the same base we add their exponents
when we multiply them together same thing with Q we have q to ^ 4 * Q to^ 5 that'll give us Q to the^ of 9 same
thing with Z in this case we have Z ^ of -1 * Z to the power of 3 in this case what we have is z to the power of 2
because it's 3 - 1 or in other words 3 + 1 and as we can see our answer then has to be answer Choice B here's how to find
the median on the SAT question Six States what is the median of the data shown we're going to start by getting
rid of our minimum value then our maximum value then our next minimum value then our next maximum value then
our next minimum value then our next maximum value then our next minimum value then our next maximum value to
find our answer of 79 now what if we had two values in the middle and we didn't have an odd number total of values we
had an even number well in that case let's say for example that we had 79 + 81 as or in this case I guess we'll use
82 since that's the one that's left of it but it's all arbitrary we've already answered this question but I just want
to show you what we do in that case in that case we had 79 plus 82 we divide by two we take the average and we use that
as the median here's how to solve this sat math question in under 30 seconds the question States what value of x is
the solution to the given equation well we got to isolate X then so let's go and subtract 40 from both sides 95 - 40 is
going to leave us with 55 is equal to X so the value of x that is a solution to give equation is 55 here's a tip to be
way more efficient on the SAT question 8 States the solution to the given system of equations is X Y what is the value of
x plus Y what you always want to do on the SAT is look for what you're asked to answer with in this case that's a of X
Plus y so does that mean we need to solve for x and y not necessarily and I'll show you why here if I see I have
stacked equations like this I'm almost always going to look to add or subtract the bottom equation from the top
equation and sometimes that will also mean I need to multiply by some number but in this case I don't need to
multiply by a number and what I see immediately is I have 5x and 4x and I have to get x + y so what I'm going to
do here is I'm actually just going to add these equations together and that's going to give me x + y because 5x +4x is
going to leave me with X and then I have plus Y is going to equal 15 + -2 which is equal to 15 minus 2 which is equal to
13 so our answer there is C and we don't have to solve for x and y because we were able to get the value of x plus y
here's an example of how to interpret a word problem on the SAT Math section question n States the given function G
models the number of gallons of gasoline that remains from a full gas ttin in a car after driving M miles according to
the model about how many gallons of gasoline are used to drive each mile well we know that g of M is how much gas
remains in the tank okay presumably since before we have driven any miles this number here is going to end up
being zero since M would be zero we would start with 12.1 gallons of gas which means that for every mile M that
we drive we are losing 0.05 gallons of gas so our answer would have to be answer Choice a here's an example of how
to solve questions that ask you to rearrange variables on the SAT Math section in this case we're asked the
given equation relates the positive numbers B X and Y which equation correctly expresses X in terms of being
y well in order to get our answer we have to isolate X so let's go ahead and do that by multiplying both sides by y
to start and then to get 11x to just X we have to divide both sides by 11 and now we have isolated X so we have y over
11 * 7B which as we can see 11 * 7 is going to give us 77 and we would have y over 77b here's how to solve this sat
math question in two different ways question 11 states the graph of the given equations in the XY plane
intersect at the point XY what is the possible value of x X now many people would go through and solve this by hand
so let's go ahead and do that and then I'll talk about the other way you can solve this one so you have y = 76 and Y
X2 - 5 in this case we can go a and plug in 76 for y so we have 76 is equal to x^2 minus 5 the next thing we'll do is
we'll isolate that x s value so we'll add five to each side and we'll end up with 81 is equal to X2 from here you
should be able to recognize that your answer is going to be positive and negative 9 for the value of x but I'll
go and show you how we do that we take the square root of both sides which is going to give us Plus or - 9 is equal to
X X the reason why it's plus or minus is because x^ squ if you put in a negative number it will still become positive if
you put in a positive number it will become positive because it's being squared so our answer there would be B
now here's what I want to show you about this question that's the way I just showed you is one way to do it and it's
perfectly fine but there is another way to do it this question is from the digital sat which means you'll have
access to Desmos while you are taking the SAT and this is another perfectly valid way to do it you just put in both
equations in Desmos and you find where they intersect which in this case we can see here is at9 so both ways are valid
the way I would recommend approaching it is with a question as simple as this you can do it by hand if you want to and if
you are very confident for example if you're someone who's consistently scoring over 1,400 on SAT practice tests
in particular over 700 on the math section and you come across this question you think it's faster for you
to do it by hand that's fine you can go ahead and do it if you're someone who's scoring less than 700 on the SAT Math
section on practice test I'd use Desmos in my opinion now that you can use Desmos on the digital sat you should be
using it fairly often for questions that involve graphing because it helps you avoid human error so even on a question
as simple as this if someone wanted to use Desmos I wouldn't fault them at all and I wouldn't tell them not to Desmos
is a great tool for the digital sat and you shouldn't be afraid to use it here's how to solve this sat math question
about the solution to a system of inequalities the question States the point x and 53 is a solution to the
system of inequalities in the XY plane which of the following could be the value of x so in this case we need to
solve for x and we already know that this point is a solution so what we're going to do is we're going to take this
53 Y and we're going to as which is a y value we're going to plug it in for y so pretty simple on how we're going to set
this up it's going to end up being 40 I'm sorry 4x + 53 must be less than 18 okay now that we've got this set up
let's go ahead and isolate X and solve for it so we'll subtract 53 from each side that'll end up leaving us with -35
must be greater than 4X from there we want to isolate X as I said so we divide both sides by four now we see that X
must be less than -35 over 4 now what you should be able to recognize here is that 35 over 4 pretty close to 36 over 4
or in other words 9 okay so we know that X has to be less than 35 over 4 which means X cannot be55 or 9 because they do
not pass that inequality the only number that does here is answer Choice a here's how to efficiently answer this sat math
question about percentages as well as one thing you want to look out for on questions that are simple like this one
question 13 states that out of 300 seeds that were planted 80% sprouted how many of these seeds sprouted so it's pretty
easy to get to our answer it's going to be 0.8 to represent that 80% we're going to multiply by 300 and that is going to
give us our answer of 240 now what you want to watch out for on questions that are as simple as this one as whether or
not the SAT is going to put something like this how many of these seeds did not Sprout okay and they would probably
underline the word not okay because that would change the math right if you're calculating for the percent or the
amount of seeds that didn't Sprout then you would end up with 60 so that is something you want to watch out for on
questions on the SAT that are simple like this is whether or not there's something that could trip you up like
that here's how to efficiently answer this sat math question question 14 States the function f is defined by F
ofx equal 4X for what value of x does f ofx equal 8 well since we're asked to find the value where f ofx equals 8 we
go and plug in 8 for f ofx which leaves us with 8 is equal to 4X from there we just want to isolate X by dividing both
sides by 4 8 over 4 is equal to 2 which means that the value of x would be two and two is our answer here's how to
efficiently answer this sat math question that deals with division and factors question 15 states which
expression is equivalent to 8X * x - 7 - 3 * x - 7 all over 2x -4 where X is greater than 7 immediately what I'm
seeing is I have x - 7 here and here so what I'm going to see is if I have x - 7 in my denominator which in this case I
see I do because I have 2x - 14 and I can change that into 2 * x - 7 so from here what I'm going to do is I'm going
to go and rewrite this division problem so you can see what I'm looking for a little bit more neatly the way we
rewrite this is 8x * x - 7 all over 2 * x - 7 - 3 * x - 7 all over 2 * x - 7 and now that we've Rewritten this it's very
easy to see that these x - 7s are going to cancel out which makes this equation very very simple okay ultimately we have
8x - 3 all over 2 which once again we can rewrite this as 8x - 3 all over 2 which we see as answer Choice B so to
answer this question what you really need to understand is one how to factor so you can get that x - 7 out and then
second how to sort of change between these similar um sort of forms right of division right you can write 8x - 3 over
2 like this and you can also write it like this so that's really what you need to understand for this question here's
how to find the slope of equations in standard linear form and use that slope to answer questions very quickly
question 16 States line p is defined by 2 y + 18x = 9 line r is perpendicular to line p in the XY plane what is the slope
of line r in order to find the slope of line r we need to first know the slope of line P now the first thing you're
going to notice is that we have 2 y + 18x = 9 this is called standard linear form it's when we have our Y and our X
on the same side being added together and there equal some constant now because it's in standard linear form we
can use the equation M = A over B where a is the value or the coefficient in front of X and B is the coefficient in
front of Y so in this case that would be m equals a in this case our a value is 18 so8 over 2 which is going to equal -9
now in order to get a perpendicular slope to -9 you have to do the negative reciprocal so9 is the same as9 over 1 so
to do the negative reciprocal we have to change the sign from negative to positive and then we have to flip the
fraction to 1 over9 so 1 over9 will be our new slope of line r so we can go slope of R which means that our answer
has to be answer Choice C here's an example of why you need to know the exponential growth formula for the SAT
question 17 States the given function f models the number of coupons of company sent to their customers at the end of
each year where T represents the number of years since the end of 1998 and zero or and T is between 0 and five inclusive
if Y is equal to F of T is graphed in the Ty y plane which of the following is the best interpretation of the Y
intercept of the graph in this context your Y intercept when you have an exponential growth formula like this is
going to be where T is equal to Zer where the exponent is equal to zero and when that exponent is equal to zero 0.65
the^ of 0 is just one and you end up with this Y intercept of 8,000 now in this case we know that that is at the
end of 1998 since that's our start year that is where T is zero so from that it's very easy to find the answer so
let's go a and read through a through D and let's find the answer a the minimum estimated number of coupons the company
sent to their customers during the 5 years was 1,4 and no B the minimum estimated number of coupons company sent
to their customers during five years was 8,000 no this is just the value at the beginning of the time so this is the
number of coupons that they sent at the end of 1998 uh and then see the number of coupons the company sent to their
customers was 1,428 no we know it's 8,000 8,000 is our initial value D the estimated number of coupons the company
sent to their customers at the end of 1998 was 8,000 yes D is our answer here's something you need to know about
similar triangles for the SAT Math section question 18 states that triangle XYZ is similar to Triangle RS t such
that X Y and Z correspond to RS and T respectively the measure of angle Z is 20° and 2 X Y is equal to RS what is the
measure of angle T the answer is C 20° now how do you know that right away well this piece of information is completely
irrelevant and you don't need to know it in order to know the answer is 20° and here is why you are told that these are
similar triangles you are also told that Z corresponds to angle T these two angles correspond to one another which
means that they must have the same angle measure so this piece of information does not matter okay all you need is
that angle Z is 20 angle T must also be 20 and your answer is C here's what you need to know about systems of linear
equations that have no solution on the SAT question 19 States one of the equations in a system of two linear
equations is given the system has no solution which equation could be the second equation in the system first
thing we need to know is our slope which we see is going to be six okay we see our Y intercept is going to be 18 now
the reason we need to know all these things is because in order for a system of linear equations to have no solution
they need to have the same slope but a different Y intercept next thing I notice is answer choices a through are
all in standard linear form which means that we can use the formula m = a b where m is representing the slope now if
we do that for answer Choice a we see that answer Choice a would be6 which would give us positive 6 over one since
one is the coefficient FR y so answer choices A and B I see are both going to have a slope of six now they have the
right slope but which one of them has the correct Y intercept and by correct Y intercept it means the Y intercept that
is different from the one that we are given because if they have the same Y intercept there is infinitely many
solutions and as we can see answer Choice a has y being equal to 6X + 18 if we were able to convert it to slope
intercept form and in that case it's the same equation as is up here so a is incorrect because that would be the same
equation and there are infinitely infinitely many solutions to that now B has a different Y intercept its Y
intercept here is going to be 22 so our answer is going to be as Choice B has a different Y intercept with the same
slope so there is no Solutions possible here's how to quickly solve this question about area on the SAT Math
section question 20 States what is the area in square centim of a rectangle with a length of 34 cm and a width of 29
CM this question is pretty easy all you need to know is the area formula for a rectangle and that's going to be the
length times the width these are both the same unit they're both centimeters that's one thing you do want to watch
out for on the SAT is if you have different units for one side than the other then You' have to convert units in
this case we do not have to do that and it is very simple it is just 29 * 34 we are able to use the calculator on the
section this is the digital sat so you're going to be able to use your calculator on both of the sections for
the math so you just put it in your calculator you're end up with 986 as your answer here's a bunch of tips that
I can illustrate with this question to help you Ace the SAT question 21 states the solution to the given system of
equations is XY what is the value of x minus y anytime that you're taking the SAT Math section you always want to pay
very very close attention to what you're asked to answer with that is the key to moving faster and being as efficient as
possible know what you want to answer with in this case they're asking for the value of xus y so what I would do is if
I have a system of equations like this I would look for if there's a way that I can do an addition or subtraction of
this bottom equation from the top one in order to get the value of xus y right away and sometimes that may involve
multiply one of these equations by some number now in this case I don't see any way
that I can quickly get to xus Y doing this so it's not applicable here but we still have the plus minus in order to
get the value of x quickly and I'll show you how we're going to do that okay like I said sometimes you're have to multiply
in this case I can see that I have y and four y so I'll just multiply this top one by four to get rid of my y so I'll
do subtraction here okay so I distribute this four to the Y I get 4 Yus 4 y now my y's are gone okay so I'm going to end
up with zero here and then I'm going to have four 4 * 4X 16x - 15x will leave me with just X then 4 * 1 I'm going to have
4 - 8 which is the same as 4 + 8 that's going to give me+ 12 so I can see here that if I subtract 12 from both sides
I'm going to end up with X is equal to -12 okay so now that I've solved for X I'll go ahead and solve for y so if x is
-2 I'll go ahead and erase up here so we can do this quickly X is -12 I'll substitute that in here so we have -12
and the reason I'm choosing this top equation is because we already have y isolated with no coefficients in front
of it so keep in mind that's strategic now that since I need y now I'm not going to pick the Y that has a
coefficient in front of it that doesn't make sense to do we want just go ahead and get y right away so we plug in that
-2 with multiply it by 4 we get -48 -48 + 1 is going to equal -47 okay so now we want the value of x minus y that's going
to be -12 minus -47 okay so keep in mind subtracting a negative it's the same as adding so we're going to have -2 + 47
and that is going to give us our answer of positive 35 here's what you need to know about calculating the number of
real solutions for quadratic equations on the SAT Math section question 22 States how many distinct real solutions
does a given equation have well in order to solve this we're going to use b^2 - 4 a c because this is a quadratic equation
now if the value of b^2 - 4 Z is positive then that means that there are going to be two real solutions now if
the value of B ^2 - 4 a c is equal to zero then that means that there are going to be one real solution and I
should have said there is going to be one real solution don't at me in the comments okay and then b^2 - 4 a c if
that is less than zero then that means that you're going to have no real solutions okay now that we've gone ahead
and gone over the value of b^2 minus 4 a c and what that means for the number of real solutions let's go and calculate it
so your B value is what's in front of the X your a value is what's in front of your x s and your C value is your
constant keep in mind it must be set equal to zero for this to work so b^2 - 4 a c our B value is 10 10^ 2 - 4 * 5 *
16 what is that equal out to that is going to equal out to -2 20 we know is less than zero therefore we must have no
real solutions so our answer is going to be d0 there are zero real solutions here's how to convert units on the SAT
question 23 States a certain park has an area of 11, 86388 square yards what is the area in
square miles of this park and one thing I want to point out here is anytime you have something underl on the SAT it
means you need to pay very close attention to it in this case it's because we're converting units from
square yards to square miles that being said we are given what one m is equal to in yards and that's 1760 so the key to
this question is that you are dealing with square yards not just yards square yards not cubic yards square yards
that's the key to this whole thing this makes it super easy as long as you understand that what you're going to do
here is you're going to take your 11, 86388 and you're going to divide it by 1760 squared and the reason why you have
to square that 1760 is because you are dealing in units of square yards to square miles so you have to square that
conversion unit as well well once you do this you just put it in your calculator and you're going to end up with
3.83 so your answer there is going to be answer Choice B here's how to use the circle equation to answer this question
on the SAT question 24 states which of the following equations represents a circle in the XY plane that intersects
the y- axis at exactly one point well first I'm going to quickly teach the circle equation to anyone who doesn't
know it so the circle equation we can write as this x - h^2 + y - k^2 is equal to our radius squ where R is our radius
okay now in this situation we would have a center for the circle of h k so as you can see you want to pay attention to the
fact that we have those minus signs but our Center is still at H and K so now that we've gone over that I'm going to
quickly show you how I would approach this the first thing I would take a look at is what my radius value is for all of
these now keep in mind 16 is the radius squared which means that the actual radius here your radius is actually
going to equal four okay and that's important because we're only intersecting the y- axis at one point
and if you're ever kind of in doubt on a question dealing with sort of circles and graphs go ahead and draw it out it's
very useful so I'll go ahead and draw that out to illustrate what I'm looking for here so if I know my radius is four
if my x value is anything greater than four and I'll put four here for example I see that my x value for the center
right is going to be eight for A and B there's no way that I can reach that Y intercept right no matter where my Y is
there's just no way I can get there because my radius is only four so I can get rid of A and B already okay I have
to find somewhere where I'm either at four or I'm at4 and the only place that that happens
and keep in mind I'm specifically referring to the x coordinate for your Center here and we see the only place
that that happens is C and answer Choice D we see that X's Center is at zero now if we had a center at zero we'd end up
with a circle that looks like this right and we're crossing that Y intercept twice so our answer there has to be
answer Choice C here's a term that you need to know for the SAT Math section question 25 States in triangles ABC and
D EF angles B and E each have measure 27 we see that B and E are here okay so they match up in that triangle angles C
and F each have a measure of 41 we see C and F they also match up in this triangle which additional piece of
information is sufficient to determine whether triangle ABC is congruent to Triangle DF key thing to understand here
and pay attention to is the fact that we are asked about congruency which means that they are the same triangles we are
not asked about similarity two triangles that are similar can have different side lengths but two triangles that are
congruent must have the same side lengths and the same angles now we already know that these triangles are
similar because if two out of these three angles are the same that means the third angle is the same in them as well
so what we need to know then is if the side lengths are all the same and the way that we can get that we can't get
that from just one side length cuz that's only from one of the triangles okay we can't get that from another
angle measure we already know they're all the same we do need more information because we need to know whether or not
these side lengths are the same and to do that we need to get these side lengths of two corresponding sides which
we see we get here in BC if we go up here BC right here these last two letters in EF okaye our answer there has
to be C and once again make sure you understand the difference between congruency which is when triangles are
the exact same and similarity which is just when they have the same angle measures this is one of the most
difficult SAT Math questions and it has less to do with the actual math involved and more to do with the actual logic
that's required to set up the problem so with that being said let's go ahe and go over it and let's simplify it down so
question 26 States the two data sets of 23 integers each are summarized in the histograms shown for each of the
histograms the first interval represents the frequency of integers greater than or equal to 10 but less than 20 so the
key thing that we need to understand here is that this line right here right this 30 number is included inside of
here right so it's really going whatever is sort of inside of a box keep in mind it's it's sort of the zero through nine
it doesn't include that next zero okay so that being said let's keep reading through the second interval represents
the frequency of integers greater than or equal to 20 but less than 30 and so on what is the smallest possible
difference between the mean of data set a and the mean of data set B so as you can see pretty much sort of a logical
sort of question as for the setup of this right so to get the smallest possible difference between these two
data sets you want to keep a couple things in mind first of all if you ever have histogram on the SAT you want to
pay attention to the shape of them now if you have two of them like you do in this case you want to pay attention to
the shape of each of them and as we can see the shape of them is the same there's there's just a shift right so
the actual shape is the same as you can see this one right here goes across into nine this goes to seven this goes to
four this goes to three same thing over here we have three four seven and nine right we have the same number of bars
obviously so these are the same shape but you want to also pay attention to your x-axis as well and as we can see
data set B is shifted to the left 10 for each of these right so now in order to set up the smallest difference in means
we would actually have to calculate the mean of each right but we don't just calculate the mean because we can't
right it's a histogram we know that these numbers fall in between these so the key thing we need to recognize is in
order to find the difference we need to know which one's larger and which one is smaller now this data set a it has to be
larger because all of these are shifted to the right okay so they can't all fall in the same number because as I pointed
out right this 30 and this is true for all of these you know these these uh rectangles or these bars on the graph
it's not inclusive of you know this for example right it's it's 20 to 29 that doesn't include that 30 right that 30 is
its own and that's what makes it so there has to be a difference here okay so we already know that the answer can't
be zero because like I said there has to be a difference um you know because we are dealing with the fact that it's 20
to 29 30 to 39 and so on so if we are shifting one of them you know to to the in this case to the right right if
you're doing from B to a it would be to the right if you're doing a to B it would be to the left there has to be
some difference there okay so that being said let's go and calculate that difference well if we're going to
calculate what the smallest difference is we need the minimum value for data set a and we would need the maximum
value for data set B because we are subtracting B from a okay so let's start with getting the minimum value of data
set a okay so minimum value of data set a let me go ahead and go up here okay so minimum value of data set a what we
would do to set this up is we would start by getting the lowest value from from our first bar right so that's going
to be 20 okay so we're getting our minimum value of a so that' be 20 * 3 okay and then we'll have to add on to
that 30 * 4 and we'll have to add on to that 40 * 7 and then we'll have to add on to that 50 * 9 okay and then once we
get that we're going to have to divide by our total which is going to be 3 + 4 which is 7 7 + 7 which is 14 and then 14
+ 9 which is 23 okay so we're going to take all that we will divide it by 23 okay now keep in mind that we're going
to also have that division by 23 over in data set b as well all right now we have to calculate our number for data set B
and I'm going to have to scroll down a little bit just so you can see all of this getting written out so go ahead and
try to scroll down Okay so we're going to have to set up a pretty similar thing right so I'm going to go and put in our
subtraction sign and I know it's not super great formatted but that's okay all right so we're going to have minus
now we have to do kind of the opposite thing that we just did a so in this case we're taking our maximum values now keep
in mind that our maximum values are not inclusive right so this is a range of 10 to 19 okay so we have to take 19 there
so that' be - 19 * 3 + 29 * 4 + 39 * 7 + 49 * 9 okay and this is all also over 23 okay and then when we put this into our
calculator which is what you would do okay I wrote this out you would just be typing this in in your calculator okay
this is ultimately going to get you your answer of one so your answer there is going to be B and that's how you solve
this this tricky SAT Math problem here's something you need to know for the SAT and that's how to extract numbers from
underneath the square root question 27 States a triangle has legs with lengths of 24 cm and 21 cm if the length of the
triangle's hypotenuse in centimeters can be written in the form 3 * theun of D where D is an integer what is the value
of D well in order to get in this form of 3 * root D we need to First actually know what the hypotenuses length is so
let's go ahead and solve for that so we have a right triangle we know we have lengths of 24 and 21 as our side lengths
we need to solve for hypotenuse which we're going to represent as c^ s we're going to use Pythagorean theorem so
we're going to go ahead and do 242 + 21^ 2 that's going to equal c^2 okay we know that this is going to equal let's put it
in our calculator and we're going to get 1017 okay so we'll take the square root of each side to isolate C okay so we
know that c is going to equal that square OT of 107 okay so now that we have that I'm going go ahead and write
this out a little bit more neatly we know C is equal to otk of 1017 C is our hypotenuse so that's what we're trying
to solve for now we need to ultimately rewrite this in a form where three is extracted okay well underneath the
square root in order to extract the value of three we would have to have the value of nine underneath that square
root and the way we get that just pretty simple right it's by three squared okay since we have a square root here we'd be
squaring three and we would get nine all right so now what we have to do is we have to do 1017 divided 9 and that's
going to give us 113 and now what we do is we set this equal to 9 * 113 which as you can see is still going to equal 1017
since we had 10 17 over 9 equal 113 so because of that we now have 9 underneath the square root which means that we can
extract three because and I'll just write this over here okay because theun 9 * 113 is the same as < TK 9 * < TK 113
and what is root9 equal to well root 9 is equal to 3 okay so now we've extracted that three and we see we have
3un 113 which is the same format as we got in this question so we know the value of D has to be 113 as well so our
answer is 1 13 here's how to solve this sat math question in under 30 seconds question one States what is the solution
to the given equation all we have to do here is isolate K by subtracting 12 from both sides 336 - 12 is 324 so we know
that K will equal 324 and our answer is B here's how to efficiently solve this sat math question question two states
the function f is defined by F ofx equal to X Cub + 15 what is the value of f of two in this case all we have to do is
plug in two for x and we're going to get 2 cubed which is equal to 8 and we have to add 15 to that so 8 + 15 will leave
us with 23 so our answer is C here's how to interpret this sat word problem question three states that Shawn rents a
tent at a cost of $1 per day plus a onetime insurance fee of $10 which equation represents the total cost C in
dollars to rent the tent with insurance for D days we know our total cost is going to equal our onetime insurance fee
of $10 plus our $1 per day giving us our answer as answer Choice C here's how to quickly solve this sat math question
about intersecting parallel lines question four states in the figure shown line M is parallel to line n what is the
value of x well we know that this angle of 26 is also going to be the same angle that is right here therefore we know
that we have this semicircle of X and angle that is 26° so we can do 180° for that angle of the semicircle minus the
26° and then we're going to get the value of x in degrees which we know will equal
154 so our answer is answer Choice D so I'll go and scroll down so you can see that our answer will be D here's how to
be more efficient on the SAT Math section question five states that John paid a total of $165 for a microscope by
making a down payment of $37 plus P monthly payments of $16 each which of the following equations represents the
situation as you can see as I read through the problem I wrote down the equation that I would eventually come up
with so we see that our answer there has to be C now I want to talk about why this is a good strategy and when to use
it what I do is when I see an SAT math question with three lines or more then as I read through the question I'll
start writing down any coefficients variables or key units that I will need to solve the question so as you saw when
I saw I had a total of 165 I knew I was probably going to sum up something else to get to that total of 165 so I wrote
down 165 first then as I kept reading I saw I had a down payment of $37 a down payment is a one-time payment so there's
not going to be a variable next to it so I went ahead and wrote down 37 okay and keep in mind I'm trying to add up to a
total here so I could probably insinuate that I'm going to have a summation after that then we have plus P monthly
payments so plus indicating I need to add plus P monthly payments of $16 each in this case p is our variable
representing the monthly payments and our coefficient in front of that is $16 each which is how I was able to write
out this equation before I finished the question okay so this is a key strategy I recommend you use on the SAT when you
have a word problem that is three lines or longer here's how to solve this sat math question in under 60 seconds
question 6 states that if Y is equal to 5x + 10 what is the value of y when X is equal 8 well all we got to do here is
plug in 8 for X we're going to have 5 * 8 which is going to give us 40 40 + 10 is going to give us 50 and our answer
will be 50 here's how to interpret bar graphs on the SAT Math section question seven states the bar graph shows the
distribution of 419 cans collected by 10 different groups for a food drive how many cans were collected by group six
well let's first take a look at our y- AIS we see we have their number of cans we need to know how many cans were
collected by group six so we find group six we see that they collected 40 cans so the answer there is 40 here's how to
efficiently solve this sat math question about probability question 8 says the table gives a distribution of votes for
new school mascot and grade level for 80 students if one of these students is selected at random what is the
probability of selecting a student whose vote for the new mascot was a lion so a couple key things to look for on
probability questions number number one is look for the pool that you are selecting from in this case we are
selecting one of the students at random keep in mind sometimes they may ask if we are selecting a seventh grader an
eighth grader sixth grader if we are selecting one of the students who voted for the badger mascot so you always want
to pay attention to the pool that you are selecting from in this case it's just one of the students so that means
we're going to be P pulling from this total right here okay now the key thing here is we are looking for uh the
probability that student vter for mascot that was a lion okay which we see is going to be this value here so our total
probability then is going to be 20 which is the part that we are selecting which is these those students who voted for a
lion over the total that we are selecting from which is all of the students so 20 over 80 is going to equal
1 over4 so if we go and scroll down we're going to see that that'll be answer Choice C so c will be our answer
there here's how to interpret slope in context for the SAT Math section question n States the graph represents
the total charge in dollars by an electrician for X hours of work the electrician charge is a one-time fee
plus an hourly rate what is the best interpretation of the slope of the graph well we know that he has a onetime fee
which is already represented by our Y intercept and then the slope is representative of his hourly rate okay
so we have option A the electrician's hourly rate and that'll be the correct answer there here's how to solve this
sat math question that is really a proportions question but disguised as a perimeter question question 10 states
that square X as a side length of 12 CM the perimeter of square Y is 2 * the perimeter of square x what is the length
in centimeters of one side of square y well couple things to keep in mind here one these are both squares number two
the perimeter is going to be the same equation for both of them just with a different value for the side length so
if we want to actually double the perimeter all we have to do is actually double the side length and because we
know that we know the answer is D having to do very little math here keep in mind we didn't actually have to calculate the
perimeter for either Square X or Square y because we're able to recognize that the equation for the calculation of the
perimeter is the same the only difference is the actual side length so if we wanted to double the output of the
perimeter or double the perimeter value in this equation all we have to do is double that side length because the
equations are set up the same here's how to quickly solve this math question question by understanding slope and Y
intercepts question 11 states what is the equation of a line that passes through the point 05 well the point 05
means that we have a y intercept of five because that x coordinate is zero so that is where we are crossing the Y AIS
and is parallel to the graph of y is equal 7x + 4 in the XY plane well if we're parallel to the graph of y = 7x +
4 that graph has a slope of seven and since we're parallel to it we also must have a slope of seven so we know that
our slope must be 7x okay so slope equals 7x we know our Y intercept must be 5 okay so our y inter intercept must
be 5 therefore we know that our equation has to be B yal 7x + 5 here's how to efficiently solve this sat math question
by understanding how to calculate slope and why intercept quickly question 12 states in the linear function h h of 0
is 41 we know that when we have H of 0 f of 0 g of 0 any function where we have that Zer as our x coordinate then we are
getting our Y intercept so in this case our Y intercept is 41 then we have H of 1 is 40 immediately uh I'll go and
finish reading the question first which equation defines h well immediately what I see here is that we are moving over
one okay so if we go over one we see that we are going down by one from 41 to 40 okay so netive 1 over 1 is going to
be our slope okay so a ne1 coefficient for our slope so now we have our Y intercept of 41 we have our slope of
negative 1 it's very easy to find Define this equation all right so we're going to have that Negative X as our slope so
our B is incorrect because it doesn't have that 41 as our Y intercept okay so a is our correct answer there we've got
Negative X is the slope plus 41 Y intercept answer there has to be answer Choice a here's how to quickly solve
this sat math question by understanding the equation for exponential growth question 13 states the function f of T
is equal to 60,000 * 2 the Power of T over 410 gives the number of bacteria in a population T minutes after an initial
observation how much time and minutes does it take for the number of bacteria in the population to double well we know
that we are doubling when we have this two to the power of one this two is our growth factor this 60,000 is our initial
amount and this T over 410 is representing how often we are doing this doubling okay and we will double every
410 minutes okay because at 410 minutes we'll get our first double and then if we go up another 410 then we'll get our
second double okay in this case we are asked for the amount of time it takes for the population to double only one
time so T would be 410 and our answer will indeed be 410 here's how to translate graphs up on the SAT Math
section question 14 States the function f is defined by f ofx is equal to x - 6 * x - 2 * x + 6 in the XY plane the
graph of yal G ofx is the result translating the graph of y f ofx up four units so keep in mind our F ofx graph is
already defined up here what is the value of G of0 in other words that's the Y intercept of G ofx okay now keep in
mind that g ofx is f ofx translated up four units so we have to start by finding what the Y intercept is of F ofx
and then add another four units on top of that since G of X is a translation up four units of it all right so let's go
ahead and solve for first the Y intercept of f ofx so we know that the Y intercept is where X is z so let's go
ahead and plug in 0 for X so we'd have 0 * or 0 - 6 and then 0 - 2 and then 0 + 6 okay this is all going to equal out to
-6 * -2 which will give us pos2 pos2 * 6 which will give us 72 okay so now we have our Y intercept for our F of 0
right now G of0 is what we need to solve for here and we know that's going to be up four units so that means that g of0
will equal F of 0 which we know is 72 + 4 which means that g of 0 will equal 76 and our final answer will be 7 6 here's
how to efficiently solve this sat math question question 15 states a candle is made of 17 ounces of wax when the candle
is burning the amount of wax in the candle decreases by 1 o every 4 hours if 6 ounces of wax remain in this candle
how for how many hours has it been burning okay so we know that we start out with 17 ounces we know that we are
going down by 1 qu ounce every hour so in this case I'm having X represent hours and the way that I got this minus
1 quar x is by the fact that we're losing 1 oun every 4 hours that means every hour we are losing 1 quarter of an
ounce all right so from here the way I'm going to set up my equation is actually setting it equal to how many ounces are
remaining okay so the amount of ounces that are remaining I'm going to call F ofx okay and that's going to equal our
initial amount minus how much we're losing every hour and keep in mind hour I'm representing as X here all right so
now from here we want to find if 6 ounces remain okay so that would mean that we have six remaining and that's
going to equal our starting amount minus 14 x now we want to solve for what time for how many hours it's been burning so
we want to solve for x now that we have this equation we'll go ahead and subtract 17 from both sides that's going
to end up giving us -11 is equal to - 1/4x from there we will multiply both sides by -4 in order to get rid of this
minus one4 okaye so we multiply both sides by -44 * -11 is going to give us POS 44 is equal to X so our answer will
be 44 here's how to rearrange variables on the SAT Math section question 16 States the given equation relates to
numbers J K and M which equation correctly expresses K in terms of J and M all right so we got to solve for what
K is equal to so to do that we're going to isolate it by subtracting 14 J from both sides so we'll subtract 14 J from
both sides okay so now this is gone next thing we have to do is divide both sides by five to isolate K all right so now
we're going to end up with K is equal to M - 14 J all over 5 okay and keep in mind that we divided that by five all
right so let's find which equation matches up with RS we see that's going to be answer Choice a so a will be our
answer there here's something you need to know about similar triangles for the SAT Math section question 17 States
triangle fgh is similar to Triangle J KL where angle F corresponds to angle J and angles G and K are right angles if s of
f is equal to 308 over 317 what is the value of s of J okay well we know that F and J are referring to the same angle
these are similar triangles they have all the same angle measures because they have the same angle measures the value
for their signs are going to be the same when it's the same angle that is inputed in these parentheses which we see it is
okay J and F are the corresponding angles then these similar triangles okay as you can see up here it says F
corresponds to angle J therefore they're going to have the same sign values and our answer for the S of J will also be
308 over 3177 here's how to efficiently set up and solve this sat math question question 18 states the product of two
positive integers is 546 if the first integer is 11 greater than than twice the second integer what is the smaller
of the two integers okay so you want to solve for the smaller of the two integers well in this case since we have
greater and smaller I'm going to use G and S as my variables okay so G and S we know 546 is going to equal the product
of these two variables G and S we also know that the first integer which we're representing as or actually I guess
let's use F and S for the first and the second okay so we're going to use F and S all right so we know that the first
integer is equal to 11 plus twice the second integer okay that's 2 s now we want to solve for the smaller we want to
solve for S here so to solve for S I'm going to go ahead and plug in F into this top equation okay we know f is also
represented as 11 plus 2s so we're going to end up with 5 46 is equal to 11 + 2 s * s we'll go ahead and distribute our s
and then we're going to end up with 11 s + 2 s^2 okay from here we want to set this all equal to zero so we can solve
for S so we're going to subtract 546 from both sides to get 0 is equal to 2 s^2 + 11 s - 500 and 46 now this
question is from the digital sat which means that you have access to Desmos Within the testing environment okay it's
through bluebuck which is the sort of the software that they're using to test um for you to take the SAT the digital
sat so at this point what I would do is I would actually plug this into my graphing calculator so I going to show
you what I did so I put it in my graphing calculator and now it's very easy to actually solve for where it
equals zero because it equals zero where it crosses the xaxis and as you can see there's two points but we only are able
to use one of them and the reason why is because we have to remember that the product is of two positive integers so
yes there are two values where s will equal where this equation here will equal zero But ultimately there's only
one that is a positive value and that is going to be at 14 okay so 14 is going to have to be your answer for the value of
s okay so our answer there is 14 which is answer Choice B here's an example of an S math question where I would use
substitution to solve the question quickly question 19 states which point XY is a solution to the given system of
inequalities in the XY plane so I've got4 for my x value I'll go ahead and plug that in up here okay -4 + 7 is
ultimately going to give me a value of7 my y value 0 is 0 less than or equal to7 no so a is wrong B I go ahead and put in
a zero for the value of x this time and a -14 for the value of y is -14 less than or equal to 7 yes that's true let
me check my next Point okay I'd have -14 again for the value of y I've got zero here all right is -1 less than or equal
to -4 no B's wrong next one I jump up onto C I plug in zero for X again okay so I'm going to end up with s I'm going
to end up with1 and then this time I have 14 for my value of y is 14 less than or equal to 7 no it is not so C is
wrong our answer there would have to be D I will check it just to make sure that I did this correctly and as you should
if you get to a question like this and if you're using substitution on a question I actually do recommend that
unless you're in a massive time crunch you do actually check the last answer choice just to make sure you didn't mess
up because as you can see I just did like Mental Math pretty much six times so odds making a mistake for me aren't
high but for the average test taker like you could have made a mistake even I could have made a mistake uh I
definitely just came across really arrogant but I'm just going to keep going anyways I plug in 14 for the value
of x so 14 + 7 that's going to be 21 uh and then right here for the value of y 0 is 0 less than or equal to 21 yes
plugging in zero again plugging in 14 here I'm going to end up with -28 minus 1 uh so that'd be -29 okay as we can see
-29 is less than or equal to zero so our answer there would be D so I guess the quick lesson here is if you're doing
substitution try to move quickly once you do three answer choices you should still check the fourth one because
there's a chance you made a mistake so that's something I do on the SAT Math section even as someone who scored
perfectly on back toback math sections I would still check that answer D just to make sure I didn't make a mistake on the
mental math because as I said I did six basically six sort of situations of mental math before getting to answer
Choice D so there is a chance that you know anyone could make a mistake there so wanted to quickly go over that
question on substitution and with that being said let's move on here's how to solve this difficult sat math question
efficiently question 20 States what is the smallest Sol solution to the given equation to start I'm going to get rid
of these square roots by going ahead and squaring both sides from there I'm going to end up getting x - 2^ 2 which is
going to end up equaling 30X + 34 now from here I want to ultimately get this set equal to zero so I can solve for x
so to do that I'm going to go and expand x - 2 2 to do that I use the foil method so I'm going to end up with x^2 - 4x + 4
is equal to 3x + 34 now like I said I want to get the set equal to zero so that I can ultimately solve for it okay
so setting equal to Z I'm going to get x^2 - 4x but I also have to subtract 3x from both sides to get it set equal to
zero so that's going to give me - 7x total and then I have that four but I have to subtract 34 so that's going to
give me minus 30 now from here this is from the digital sat so you could plug this into Desmos and then solve for x
but in this case I want to just go ahead and show you how you could also solve for this by hand since that would be the
little bit more difficult way to do it but it could possibly be a little bit quicker depending on whether you're
skilled at factoring like this if you're not Skillet factoring you can go ahe and use Desmos like I said perfectly valid
way of doing it but in this case I'll talk to you about how to factor this so 30 you want to think about what
multiplies together to get -30 that adds to get -7 so immediately I would think -10 and positive 3 so I would end up
with x - 10 and then x + 3 okay so that's set equal to zero now from there I've got two possible solutions one
would be X is equal to 10 and one would be X is equal to -3 now keep in mind that we have to have the smallest
solution to the given equations now the smallest solution here isg -3 because it's obviously negative and the other
value is positive so our answer here would be -3 now if you were to graph this out you also still need to pay
attention to the fact that you need the smallest solution to the given equation so make sure on the SAT that you always
pay really close attention to what you're asked to answer with because if you don't you're probably going to miss
points here's how to efficiently solve this multi-step sat math question question 21 states that the regular
price of a shirt at a store is $11.70 the sale price of a shirt of the shirt is 80% less than the regular price
and the sale price is 30% greater than the store's cost for the shirt what was the store's cost in for the shirt okay
so we want to solve for the stores cost well we know that the price the regular price is 11.7 we know it's on sale for
80% so let's go and solve for the sale price because in order to get the stores cost we need to first know the sale
price so the sale price is 11.7 time 0.2 because the shirt is 80% off all right so now we have the sale price that's
going to equal our sale price so I'm just going to write that as sale well we also know that the sale price is equal
to well it's 30% greater than the store's cost so we want to solve for the store's cost so the store's cost time
1.3 is going to give us the sale price well we already know the sale price and we want to solve for cost we know that
the sale price ID 1.3 will equal our cost we have our sale price up here so we can go ahead and go like this 11.2 or
I'm Sorry 11.7 divid by 02 or I'm sorry 11.7 time 0.2 that is our sale price we then divide that by 1.3 and we get our
cost okay so now we can go ahead and plug this into our calculator and let's see what we get so we got 11.7 * 0.2 /
1.3 and that'll give us our answer of 1.8 is equal to the cost so 1.8 is our answer there here's how to efficiently
solve this sat math question about density question 22 states that a sample of Oak has a density of 807 kg per cubic
meter the sample is in the shape of a cube where each Edge has a length of 0.9 m to the nearest whole number what is
the mass in kilograms of this sample all right so we know our equation for density is mass over volume is equal to
our density in this case we total our density is 87 kg per cubic meter make sure we're paying close attention to
units in this case it's kilog per cubic meter we also see we're dealing in meters and we're asked for answer in
kilograms so we're not going to be dealing with any unit conversion so that makes this a lot easier now we know that
our mass is what we're trying to solve for okay so we know our mass then is going to equal 87 times our volume now
we have to solve for our volume we know that is from a cube which has each length of 0.9 Metter now keep in mind
our equation for volume of a cube would be the Cube's Edge length cubed okay because all these all these side lengths
are the same in a cube all right so ultimately that's going to be 0.9 cubed all right so now we've got our equation
let's go ahead and put it into our calculator and we will get our answer so we're going to do 87 multili .9 cubed
and that'll give us our answer of 588 for the value of our Mass so our answer is answer Choice a here's how to avoid a
