The GRE and GMAT Math sections want to make sure you know certain concepts – concepts that are reasonable things for a person with a graduate degree to know. A good score requires (but doesn’t depend only on) some math refreshing.

Concepts that are certain to show up include:

Quick addition, subtraction, multiplication, and division

- Squares and square roots up to 100 (4, 9, 16, 25, 36, 49, 64, 81, 100)
- Adding/subtracting fractions versus multiplying/dividing fractions
- Averages (not just finding the average of a set of numbers, but working backwards as well)
- Basic algebra equations (5x + 16 = 3x + 6. Solve for x)
- Distance, Rate, and Time
- Area and Perimeter of a Rectangle or Square
- Radius, Diameter, Circumference, Area of a Circle
- Area of a Triangle
- Pythagorean Theorem and using it to find distance

If you’re rusty, sign up to take a Math Refresher class. Make a list of math concepts you need to improve, and then focus on them one at a time. Make some flashcards or get a flashcard app and practice every time you’re waiting in line.

Don’t make the mistake of thinking that just because you have mastered all of these concepts, you’ll ace the math section. Both the GRE and the GMAT test mathematical *reasoning *at least as heavily as they test mathematical concepts. In other words, a lot of the questions depend on thinking through the problem logically, setting up several steps in a row, and eliminating impossible answer choices. This skill goes hand-in-hand with math concepts, and the people with truly good scores are good at both. That’s where a prep book or prep course comes in handy. Your teacher can help you apply your math knowledge to test-specific formats.

Use websites like “mathisfun.com,” “purplemath.com,” and “freerice.org” to check your understanding and application.
