The Math Review is designed to familiarize you with the mathematical skills and concepts likely to be tested on the Graduate Record Examinations General Test.

This material, which is divided into the four basic content areas of arithmetic, algebra, geometry, and data analysis, includes many definitions and examples with solutions, and there is a set of exercises (with answers) at the end of each of these four sections. Note, however, this review is not intended to be comprehensive.

It is assumed that certain basic concepts are common knowledge to all examinees. Emphasis is, therefore, placed on the more important skills, concepts, and definitions, and on those particular areas that are frequently confused or misunderstood.

If any of the topics seem especially unfamiliar, we encourage you to consult appropriate mathematics texts for a more detailed treatment of those topics.
