How to Ace the GRE Quantitative Section
If you are applying to graduate school, chances are you need to take the GRE--Graduate Record Examination. For many people, expecially those who have been out of school for a while, studying for the math section (or quantitative as it's officially called) can seem daunting! Add to that the fact that calculators are not allowed on the GRE. But there is hope yet: the GRE only tests math skills up to high school level. So, the more you practice, the more easily you will start to remember those old geometry formulas and how to solve for x!
If you take the General Test in the US, you will take it in a special computerized format called a "Computer Adaptive Test." The adaptive part comes into play because the test adapts to your ability. The test presents you with a medium-difficulty level question first. If you answer it correctly, you get points and the test presents you with a harder question worth more points. If you answer the question incorrectly you just get zero points and your next question is an easier one worth fewer points. Your final score is determined by the points you accumulate for getting questions right, with harder questions worth more points.

Review basic algebra. More than half of the math questions on the GRE involve manipulating variables. Remember that if you have an equation and you want to simplify it, you have to do the SAME things to BOTH sides. For example how do you solve 3x + 5 = 17? Subtract 5 from both sides: 3x = 12. Divide both sides by 3: x = 4.

Review basic plane geometry. About one third of the math question on the GRE involve lines, angles, triangles, and circles. Complicated questions will combine figures. Since the GRE will not provide you with geometry formulas, you will need to memorize them ahead of time. You should know how to find the areas of triangles and circles, how to calculate circumference, how to find the hypotenuse of a right triangle, and you should know that all the angles inside a triangle add up to 180 degrees.

Review properties of numbers. You will need to know what a prime number is, how even numbers and odd numbers work, how positive numbers and negative numbers work, and how to work with fractions. You should also have an understanding of square roots and exponents.

Review basic arithmetic. There is no calculator allowed on the GRE!!! All the calculations you do will have to be carried out on the scratch paper provided to you. Successful test takers know their times tables and long division. If you want to join their ranks, you will need to be quick on the draw with addition, subtraction, multiplication, and division. Percents appear frequently as well, so review them too.

Once you have reviewed the GRE math content, you should start timing yourself. Get a book of practice problems and set the timer! The GRE gives you 28 or 29 questions in 45 minutes, which works out to be about 1.5 minutes per question. You can take baby steps by giving yourself 2 or 3 minutes per question at first, and then work your way down.

Tips & Warnings
If you are really rusty, make sure you devote at least a month to studying before you take the exam. The GRE is offered year round, so don't take it before you are ready.
Resist the temptation to use a calculator while you study.
If you are considering paying for help, hiring a private tutor is often cheaper and more effective than expensive prep courses.
The geometric figures drawn on the exam are not drawn to scale, so don't try to eyeball them when guessing.
