Raising your SAT or ACT math score can be a tough process; you need to improve your knowledge of algebra, arithmetic, and geometry, and you need to get used to the hundreds of different question formats that these exams use to test your knowledge. But with the right strategies, you can take serious shortcuts toward progress, improving your score by hundreds of points in an incredibly short period of time.

Of all the tricks that can help you to get a better
SAT or ACT math score, there's one that makes a bigger difference than
all the others combined:

*Whenever you don't need to know a number, MAKE IT UP.*Math is about numbers - if you can work with real numbers, you'll have a much easier time solving challenging problems. So if you have the option to "plug in" real numbers and do calculations with them, rather than with abstract concepts or variables, do it. Every time.

Let's look at an example problem to illustrate this point:

"If you double the side length of a square, by what factor do you multiply its area?"

When you look at any problem like this, you should ask yourself: do
they say what the actual side length of the square is? Do they forbid
me from coming up with my own?

The answer to
both of those questions is a resounding "NO!" - this question implicitly
states that the answer will be the same regardless of the size of the
square. So instead of puzzling over a complex problem, try something
else:

Pretend that the side length of the original square is 1!

If the original square has a side length of 1, then the area is 1X1, or 1.

The new square, then, will have a side length of 2, making its area 2X2, or 4.

Thus, the answer is "4."

But what if you chose a different number?

Pretend that the original side length was 3. 3X3 equals 9, so the original area is 9.

Now double that - the new square has a side length of 6, so the new area is 6X6, or 36.

Guess what? 9X4 is 36! So even though the numbers you picked are different, the answer is exactly the same!

Whenever you're solving an SAT or ACT math problem, ask yourself this: can I make up my own numbers for this problem?

In some problems, you won't be able to. For instance, in the problem:

X-9=28

You can't make up X, since it has a definite value. But if you see a question like this:

If Mary sells X shells a day, and if she sells them for Y dollars a piece, then how many dollars will she make after Z days?

Make up X, Y, and Z, do the math, and then find the
answer. Whatever the correct answer is will give you the same exact
result when you plug in your versions of X, Y, and Z.
