Hi everyone, Alexis Avila Founder of Prepped & Polished LLC, here in
Boston. One way to boost your math score on the SAT test is to try a plug
in technique for math problems that involve variables. I am going to show
you how you can get hard level SAT math questions correct by using a plug
in technique.The question is, if Y and X are positive numbers, what percent of Y is X.
The first thing you are going to do is plug in for Y and X. Let’s make Y =2
and X =1 for this specific problem. Now you are going to reread the
question with the numbers that you assigned for the variables. So, if 2 and
1 are positive numbers, what percent of 3 is 1? The question now is what
percent of 3 is 1, pretty easy, right? That’s 33.3333%. We are just going
to say 33. That’s what I circled here is our target answer. Which means the
correct formula will render 33.Finally, plug in your numbers for Y and X into all of your answer choices
and eliminate the answers that will not give you 33, which is your target
answer. Just a shortcut here, if you plug in your numbers in A, B, C, and
D, these equations will not give you 33. But, if you go to E which is 100X
over Y + 1, let’s solve it. 100 X is 100 times 1 over 2 + 1 which is 3.
So, 100 over 3 is 33, a perfect match to your target answer. Go with choice
E and move on through the test. As you can see you make harder problems
easier for yourself when you utilize the plug in technique. Good luck on
your SAT and I will talk to you soon.

Hi everyone, Alexis Avila, founder of Prepped and Polished LLC. Now many
SAT students, even top level SAT students, make careless mistakes on their
SAT, especially on the math section.

Now remember if you make ten careless mistakes on the SAT math section,
that can cost you between 100 and 150 points, so you want to avoid careless
mistakes and this is how you do it. You’re going to underline and circle or
box key words in the math question.

For example, if A equals 2 x 4 x 6 x 8 and B equals 6 x 8, what’s the
remainder when A is divided by B. So what’s important in this question,
well, we need to know A so we’ve underlined that, and B is 6 x 8, what is
the remainder? I’m going to circle the remainder when A is divided by B.
Now you’re going to solve the question really carefully.

You’re going to clearly take A and divide it by B. So we’re going to say 2
x 4 x 6 x 8 divided by 6 x 8 which is B, we’re going to cancel and then
we’re going to solve and see that when A is divided by B you get 8. Now
this is where a lot of students make a mistake, even top level students.
They’re going to get so excited and wrapped around the fact that they
solved the question that A is 8 that they are going to circle E.

We’re going careful work and so we know that we are looking for the
remainder, and the remainder is clearly zero, there is no remainder when A
is divided by B. You’re going to circle A and move on. We’ve done careful
work. Now what you’re going to do to avoid careless mistakes in the math
section is you’re going to underline or circle key concepts, key words in
the math question. And then you’re going to reread the question and know
exactly what to look for in the SAT question.

I wish you good luck, and I’ll talk to you soon.
