This book gives you both. • “Top 10 Ways to Raise Your Score” includes some of the most valuable test-taking strategies to help you score high on the GMAT as well as a chart to help you track your progress. • Part I provides essential information about the GMAT, including where to take it and how it is scored. You’ll also learn what subjects are covered and what traps to watch out for. • Part II is a full-length diagnostic test, which is your first chance to work with samples of every GMAT question type. It can show you where your skills are strong—and where they need some shoring up. • Parts III through V are the coaching program. They analyze each question type for you and give you powerful test-taking strategies. These strategies are based on more than 20 years of careful study of the GMAT. • Part VI is a full-scale review of GMAT mathematics. If your math skills are rusty and need refreshing, this section is for you. • Part VII contains five practice tests followed by detailed answer explana- tions for each question. The answer explanations are very important because it is there where you can learn from your mistakes. • The Appendixes contain critical information on how to create a winning business school application, including a before and after look at two personal statements.
