The Official Guide for GMAT Review, 10th Edition

内容架构和第11版差不多，你可以参考一下：

The book is divided into ten chapters:

Chapter 1: A overall, general description of the test.
Chapter 2: How to answer GMAT questions on the computer.
Chapter 3: A general review of math. Includes arithmetic, algebra, geometry, and word problems.

The next five chapters all follow the same format: Brief strategies for answering each type of question, actual questions, then the answers and explanations for these questions. Another minor difference between the 9th and 10th editions is that the 10th edition does not have all the answers on one or two pages; all the answers are contained in the explanations.
