Before I write about this book, I want to stress that it is essential to practice taking the GRE via computer. You can download the software here.

The 340 page QR practice book is the only math book of its kind by the test writers, ETS. The introduction offers an overview of the test questions. There are helpful strategies in the “Test Content”chapter. It lists tips such as “translate word problems into algebra”, “process of elimination”, “connect to what you know.”

Chapters 3 through 7 offer math practice by type: arithmetic, algebra, geometry, data analysis, then mixed review. Each of these chapters ends with answers and explanations. The numbers of problems vary per chapter: 17 in one, 26 in another.

**Who would benefit?**

This book would be helpful to anyone’s GRE Quant prep. One should work through it just to know where one stands; these are, after all, *real* ETS questions, unlike those by test prep companies. This book is not enough to support a person struggling with math, however. If one worked on the question with fractions raised to negative exponents in the mixed practice set and got it wrong, one gets a two-line answer that makes use of exponent rules one *should already know.* However, those that had no idea what to do with fractions raised to negative exponents are in need of a more intensive prep book that has pages devoted to lessons on math rules. Perhaps that person would not be sure what to do with other types of similar problems: integers raised to negative exponents, fractions raised to positive exponents, etc… For that kind of support, I would recommend a test prep company’s book, like those of Manhattan Prep, Princeton Review or Kaplan.
