class at school.
You need special techniques for handlingSAT problems.
If you do the SAT math problems like youwould do in class, you waste time and
throw away points.

Sections of the test
There are 3 sections to the Math test.
1. 20 question Problem-Solving (m.c)2. 10 Problem-Solving (m.c), 10 Grid-in
3. 15 Problem-Solving (m.c)
Questions in each section are arranged in
an special order of difficulty.

Pacing
Almost everyone works too fast on SAT tests! The testis designed NOT to be completed!
You will hurt your score by working too fast.
If you miss about 5 or 6 questions in each section, you
are probably about the right pace.
If you are NOT missing any questions but are NOT
finishing, then guess more aggressively and work
faster.

Calculators
Calculators can only calculate, they cant think!
THNINK BEFORE YOU PUNCH
Tips to Calculator Happiness:
Use a calculator that follows order of operations.
Estimate your answer first.
Check each number after you punch it in.

When do I guess?
Always be aware of where you are in the test.
Easy Questions easy answers
Hard questions hard answers
Good guess Geometry drawn to scale, where you can approximate
length or area. Any Grid-in you have an answer for.
Bad Guess Obvious answers on hard questions Long, complicated word problems Questions you dont have time to read.

Plugging In
One of the most powerful strategies on the SATs.
The idea of taking all the variables like x, y, zIn the question and replacing them with actual
numbers.
You dont have to generate the answer yourself. Itallows you to check which of the answers is thecorrect one.
This turns an algebra problem into simplearithmetic!

How do I know when to Use Plugging In?
The question will be straight forward.e.g. How old is Bob?, or How manypotatoes in the bag?
There are variables in the answer choices.
The question says something like
in terms of x
The question asks for a percentage orfractional part of something, but doesntgive you actual amounts.

Tips for Plugging-In Happiness
Pick easy numbers like 2, 10, 100 etcAvoid picking 0, 1 or any number that is one ofthe answers.
If your chosen number leads to UGLYcomputations, then bail out and pick aneasier number.
The answers are in numerical order, so youmay be able to eliminate answers that are toobig or too small. If the answer to was toosmall, then try the bigger answer choices.

Plugging-In ExampleJill spent x dollars on toys and 12 dollars on socks. If the
amount Jill spent was twice the amount she earns in a week,
how much does Jill earn each week in terms of x?
a) 2(x + 12)
b) 2x + 24
c) (x/2) + 12
d) (x+12)/2
Solution: Lets plug in 100 for x. That means that Jill spent a total
of $112. If that was twice her weekly salary, then she makeshalf of $112, or $56.
Nowplug in 100 to see which answer gives us $56.

If y / 3 = 6x, then in terms of y, x = ?
a) 3y
b) 2y
c) y
d) y / 2
e) y / 18
Answer: E. Plug in y = 36, which makes x = 2. Now
plug y = 36 into the answer choices.
