The Quantitative Section of the GMAT seeks to measure the ability to reason quantitatively, solve quantitative problems, interpret graphic data, and analyze and use information given in a problem. Questions require knowledge of certain algebra, geometry, and arithmetic. There are two types of quantitative questions: problem solving and data sufficiency.The use of calculators is not allowed on the quantitative section of the GMAT. Test takers must do their math work out by hand using a wet erase pen and laminated graph paper which are given to them at the testing center. Scores range from 0 to 60, although GMAC only reports scores between 11 and 51.
Problem solving questions are designed to test the ability to reason quantitatively and to solve quantitative problems. Data sufficiency is a question type unique to the GMAT designed to measure the ability to understand and analyze a quantitative problem, recognize what information is relevant or irrelevant and determine at what point there is enough information to solve a problem or recognize the fact that there is insufficient information given to solve a particular problem.
