The Official Guide for GMAT Review, 10th Edition
Important! The Official Guide for GMAT Review, 11th Edition is reportedly becoming available in the summer of 2005.
There is no substitute for official GMAT questions. All TestMagic students who have scored over 700 on their GMAT (currently averaging approximately 90% of all on-site students) have gone through the Official Guide (affectionately known as the "OG") two, three, four, even five times. This book is the bible of GMAT preparation.
Many people ask TestMagic why the OG is so important. They often want to save a few bucks and get by with the used books their friends have given them, or rely on the materials Kaplan or Princeton Review sell or offer in their courses. Not a wise decision.
The questions in the practice books are just not the same. Many of the practice books have mistakes and address topics that are not really related to what you will see on the GMAT. And some of the very well known books will actually lower score, if you follow what they say.
Furthermore, many of the practice books you can buy have lots of typos, some of the answers are transposed or just plain wrong. "Underground" GMAT materials are loaded with typos, typically at least two per page.
However, official GMAT questions are not like that--you will almost never be able to find fault with them (check out the TestMagic GMAT Forum for the skinny on some of the disputed questions).
The bottom line: TestMagic wouldn't sell this book if it weren't important.
This book is loaded with over 1,400 official GMAT questions that actually appeared on past GMAT's, about 400 more than the 9th edition. Almost all of the questions that are in the 9th edition are also in the 10th edition, but a few have been taken out.
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.
Chapter 4: 441 math questions, with basic strategies and explanations
of each question
Chapter 5: 274 data sufficiency questions, with basic strategies and explanations of each question
Chapter 6: 285 reading comprehension questions, with basic strategies and explanations of each question
Chapter 7: 205 critical reasoning questions, including one example of a new type of question, the "boldface Critical Reasoning " questions (question # 205, page 557), with basic strategies and explanations of each question
Chapter 8: 268 sentence correction questions, with basic strategies and explanations of each question
Chapter 9: A list of all the essay topics that will appear on your GMAT, with six samples of the essays, three samples for each type of essay. There are three samples of the Analysis of an Issue essay, with scores of 6 (the highest score), 4, and 2 and three samples of the Analysis of an Argument essay, also with scores of 6 (the highest score), 4, and 2.
Chapter 10: Information about scores, scaled scores, percentiles, etc.
