This review is designed to familiarize you with the mathematical skills and concepts likely to be tested on the Graduate Record Examinations General Test. The text includes many examples with solutions, and there is a set of exercises at the end of each section. The following material, which is divided into the four basic content areas of arithmetic, algebra, geometry, and data analysis, 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 defmitions, 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.
