August 2023 SAT Prediction: You Will See This On Your Test

hey Mike from prep Pros here and for those of you who don't already know me I've been a full-time tutor for a little bit over eight years now I've scored perfectly on the SAT myself I've published what I think is by far the best SAT Math book out there I've helped students score perfectly in just this past spring I had a handful of my students score 1550 plus including this one student who got a 1580 just using my online sat course so I know a thing or two when it comes to doing well on the SAT and in this video we're going to help you quickly improve your score for the August sat and cover 10 things you absolutely need to know now the first concept you're 100 gonna see in August is lines you'll typically see a handful of these questions but we're going to take a look at a new variety that has been giving tons of students trouble so far in 2023. here we see line K as a slope of negative four-fifths and an x-intercept of R over 2 comma zero where R is a constant what is the y coordinate of the y-intercept of line K in terms of R now what we always want to think about is anytime we're giving in the slope we simply can always solve for the y-intercept by going ahead and plugging the slope in and we're simply going to write plus b because it's y equals MX plus b now whether they give you an x-intercept or any point on the line this always gives us X and Y values we can plug in so we can solve for b so we simply have to plug in 0 for y and we're going to plug in R over 2 for x and now we can solve for b so we'll get 0 equals negative 4 R over 10 plus b so we add that over we'll get 4r plus 10 4r over 10 excuse me is equal to B and well that just simplifies down to 2R over 5 and that's how we can find our correct answer now the next concept you're 100 going to see on the test is what we think of as interpreting constants and this gives so many students trouble that I have entire basically two chapters dedicated to these types of questions so in the system of equations above K is a constant if this system has no Solutions what is the value of K well what you need to understand for the SAT is what you're looking for for the three different variations of these questions no solution simply means our slopes are the same and our intercepts are different infinite solutions means the lines are absolutely identical and for one solution your only requirement is the slopes must be different so in this instance for no Solutions we know the slopes must be the same the intercepts must be different well the intercepts are already different so we just simply need to set the slopes equal to each other so we can simply solve for K by doing three over two is equal to K over 3 we can cross multiply and that gives us that 9 is equal to 2K therefore 9 over 2 which is also the same as 4.5 is equal to K you just need to know what you're looking for and you can start to pick these questions up really easily now up next our percent increases and decreases these show up in all sorts of different forms on the SAT but we're going to take a look at these two to really teach the basic concept so we'll start with 24. in 1976 there are approximately 1 000 gray wolves in northern Minnesota the number of gray wolves in northern Minnesota in 2008 was 190 percent greater than in 1976. approximately how many gray wolves were in Minnesota in 2008. now the basic principle that the SAT loves to play around with is for percent increases and decreases it's always one plus or minus the percent expressed is basically a decimal so for a really simple example if we're doing a 70 increase that would be expressed by 1.7 1 plus 0.7 70 decrease would be the same as 0.3 so if we're showing at 190 percent increase this is going to be the same as 1 plus 1.9 1 is always equal to 100 so 190 greater is 1.9 that's going to give us 2.9 now this simply means we're going to take our 2.9 and multiply it by 1000 and that will give us our correct answer of C so as we come up to a very hard version of this the population of a city in 2000 was 2.6 times the population in 1999. the population increased by P percent from 1999 to 2000. well we're essentially just reversing the process that we did here if we were told that the number of wolves was 2.9 times greater we would be able to see that's in 190 increase because we simply would be taking away that one that we're always adding or subtracting to so here we can solve for this by doing 2.6 minus 1 equals 1.6 that's going to be our amount of increase that we've done well 1.6 is going to be the same as 160 percent and that's how we can solve these up next are quadratics and this is one of the most commonly tested Concepts on the SAT and there's all sorts of different questions you need to understand you need to know your discriminant rules sum of solutions your vertex questions that we'll cover kind of here also quadratic formula questions maximums minimums multiplicity I'm not going to run through all of that here because it's all taught in depth in my free trial and will also let you check out a chapter of my math book but let's solve question 30 from the May 2023 test for the quadratic function H the table gives three value use of Acts and their corresponding values of H of X what value of x does H reach its minimum well I'm going to pop on a screen a page from my book here because the principle that this question is testing you on is understanding that the vertex is the midpoint of your x-intercepts parabolas are symmetrical in both directions so the midpoint of those x-intercepts always gives you your vertex so all we need to do is we need to understand well h of X is the same as y we find our x-intercepts when y equals zero so that means we have x-intercepts of 2 and 4. now if the minimum part tripped you up your minimums and maximums are always found at your vertex as well so we simply are taking the midpoint of 2 and 4 and that gives us our correct answer here all right up next is exponents these show up every single sat and they are often some of the most difficult questions that you'll see on the test and the most important rule that every student forgets that they need to refresh on is the fractional power rule that's what a ton of these revolve around so here we see two numbers A and B are each greater than zero and the square root of a is equal to the cube root of B for what value of x is a to the 2x minus 1 equal to B so let's go ahead and write this out so we know the square root of a is equal to the cube root of B now we're saying a to the 2x minus 1 is equal to B so what we want to do is we want to get this expression here equal to B well first thing I want to do is use fraction Powers because this will make our life a little bit easier so we can rewrite this as a to the one-half equals B to the one third well if we want to get it equal to B we need to raise both of these sides to the third power now that's going to give us a to the three halves is equal to B well now since we know that a to the 2x minus 1 also equals B we can simply set those two equal to each other a to the 2x minus 1 is going to be equal to a to the three halves now we can cancel out our bases and we simply get 2x minus 1 is equal to 3 over 2. well we can add the 1 over so we'll get 2X equals and 1 is going to be the same as 2 over 2 equals 5 halves now we divide both sides by two and we'll get our correct answer of x equals five fourths now for grammar one of the things you're definitely going to see in the writing and language questions are questions on what is called parallel structure and particularly we have been seeing a lot of what are called illogical comparisons in the last year anytime you see comparisons you really simply need to compare apples to apples so here we see these results suggest that the red orange glow of deep water corals might indeed be a symbiotic survival mechanism just like those of corals and shallow Waters now if you ever see like those of that of this almost always tells you it's a parallel or kind of illogical comparison question and those of is a plural comparison that of is a singular comparison well what we're comparing is the red orange glow of deep water corals might indeed be a symbiotic survival mechanism just like we have to be comparing it to another glow and that's why we'd have to say the sun blocking glow of chlorals and shallow Waters we're now comparing those apples to apples glow to Glow those of would be wrong because this is plural if they said that of that could be a correct answer but that's what you're looking for with these very tricky comparison questions up next is sentence structure rules and this is one of the most important and fundamental rules for you to understand to score really highly on writing a language this is how we connect the different types of Clauses so we always know we're dealing with sentence structure if we see commas and Fanboys semicolons or periods in the answer choices so let's just take a look at our Clauses however many consumers are concerned about the trustworthiness of anonymous customer appraisals or are simply overwhelmed by the countless often conflicting reviews independent clause there is growing demand for the objective reputable reviews provided by a professional reviewing service also an independent clause so I need period semicolon or comma and Fanboys well here's the s in our Fanboys and our Clauses have stayed the same so I know that c must be correct now this is your kind of trap answer when you do not now that we have removed our independent clause here now if these are rules you aren't familiar with and you want to learn some of the important comma rules definitely check out my free trial it's going to help you out a bunch for the writing language section now up next is apostrophes almost every single sat you typically will see two of these questions and so many students miss them but they're quite easy to learn so as Abigail Derby Lewis one of the studies ecologists says so now what I always like to think about is start with possessive versus non-possessive reusing the apostrophes we're showing possession of the object well the ecologists are not possessing the says we can't say like the seds of the ecologist that makes no sense so at this point I can strike every answer that uses an apostrophe there I can get rid of a I can get rid of C well now the main difference between B and D is well are we saying the studies are showing possession of the ecologists or are we not showing possession well they are the ecologists of the study therefore I know we have to be showing possession now occasionally we'll also get this kind of other apostrophe here if you see an apostrophe after the S on the SAT that's showing plural possession in this instance it would be a little unclear to the reader whether this would be singular or plural possession that's why they only give us the option of singular possession for B here now let's talk a little bit about the reading section here one type of kind of reading piece of evidence that gives tons of students trouble is what I call inverse evidence this most commonly shows up in your two natural science passages so let's take a look at the evidence and see if we can figure this out information about woodpeckers Finch's social system can shed some light on the reasons for the strong genetic predetermination of tool use in the species for one thing in contrast to socially living primates woodpecker finches are solitary and thus parents are likely to be only available tool using models well the question is the passage most strongly suggests that social system of primates allows for young animals to wet blank well this tells us in contrast to socially living primates woodpecker finches are solitary thus parents are the only available tool using models so therefore primates are going to be inverse of this they're not going to be solitary and they're going to have more available tool using models than just parents and so that's how we can see that a is our correct answer but being aware of this type of inverse evidence makes a huge difference for some of the most missed and difficult questions on the reading section now the last thing you're definitely going to see are statistics questions these are about standard deviation margin of error sampling bias box and whisker plots show up every single SAT but this is one that they really love to put pretty late on the test but it's really easy if you know the trick so here we see mitcha and Rihanna each selected a random sample of students at their school and asked how many soft drink servings each student had consumed the previous week Nietzsche estimated that the mean number of soft drink servings was 7.1 with an Associated margin of error of 1.2 Rihanna estimated the mean number of soft drink servings was 8.3 with an Associated margin of error of 0.8 assuming the margin of errors were calculated in the same way which the fund best explains why Rihanna obtained a smaller margin of error than Misha well the simple principle you have to understand is the bigger part of a population we sample the more accurate we should be therefore we should have a lower margin Bearer so just simply remember bigger sample size gives you a smaller margin of error smaller sample size gives you a bigger margin of error so simply here we know that rana's sample must have contained more students than Misha sample now I really hope this video has helped you out here you can check out a math video to help you learn some of the most important concepts for the SAT if you're really looking to improve your score and get as high a score as possible recommend picking up a copy of my math book from Amazon or signing up for my ultimate sat course where I'm going to teach you everything all the strategies tips and tricks that have helped students improve their score by as much as 300 points and score as high as 1580 so far this year that's all also backed by a really simple 100 Point score Improvement guarantee now if you are in the last week or two and you're really just trying to cram in the most important topics tips and tricks and strategies to quickly increase your score on the SAT I recommend taking a look at my SAT crash course I've had students improve by as much as 160 points just from that alone but otherwise if you guys have any questions at
