Problem Solving
The problem solving section is designed to test your problem solving skills, not your ability to perform such problems mathematically. Advanced math topics like trigonometry and calculus are not covered on the Test. So all you have to know to have a high score on this section is basic (high school level) arithmetic, geometry and algebra. A Quantitative refresher is sufficient to have mastery on this section.
Major Topics Covered
Simple Arithmetic, Simple Algebra, Averages, Ratios & Proportions, Percentage, Sets, Work problems, Speed and Motion, Combinations, Probability, and Geometry are basic topics covered on the test.
You need not to go in details of mathematics including Calculus, Trigonometry, Binomial theorem, Conics, and so on.
The important item you must practice is simple calculations. If you spend more time on simple calculations during the test then you'll not be able to spend time on the understanding of the questions.
