Book Reviews of The Official Guide for GMAT Review, 12th EditionBook Review: A MUST-HAVE book for GMAT Test Takers! Summary: 5 Stars
I self studied and scored a 770 on the GMAT. Here are my thoughts on Official Guide 12:
===== OVERVIEW =====
The most important piece of information that you need to know about the Official Guide (often called the OG on forums) is that it contains real, retired GMAT questions. As such, material released by the GMAC (the creator of the test) is utterly priceless, since replicating the exact structure and "feel" of real GMAT questions is something that test prep companies have yet to accomplish.
The book is not exactly "travel size", but this should be regarded as a plus, since it stems from the fact that the book features 907 questions and quite generous answer explanations (particularly in verbal). The problems are structured as follows:
* 48 Quantitative and 52 Verbal in the Diagnostics Test
* 230 Problem Solving
* 174 Data Sufficiency
* 139 Reading Comprehension
* 124 Critical Reasoning
* 140 Sentence Correction
===== PROS =====
* A great, all-in-one resource for official questions, excellent for training your eye to spot commonly-tested patterns. This is the reason why I believe that it's worth investing some energy even in lower difficulty questions (unless pressed for time)
* Detailed explanations in verbal: this is something that I have not seen mentioned often, but I believe is of crucial importance. In all three sections, explanations follow a similar style: an overview of the question and a solid analysis of ALL the answers, not just the correct one. Understanding why your answer is wrong is sometimes even more important than getting it right
* Questions are arranged in order of difficulty, so if you have little time at hand and feel sufficiently confident about your knowledge, you can just focus on the last questions of each section
* Good value for your money: at just over 20 dollars on Amazon.com, getting over 900 retired questions is a bargain
===== CONS =====
* The OG is not a strategy guide, it's a "workout list". Each section contains a review of the subject, but this is not nearly enough to get you through the test, especially if your math skills are a bit rusty. You will need to rely on other resources for this!
* While verbal explanations are generally high quality, quantitative explanations are not as great. Some test takers (particularly advanced ones) will often find themselves opting for a quicker or easier way to solve the given problems. I will however note that more often than not, the OG explanations do not feature number picking. While this is sometimes a faster way to solve a problem, its use is confusing for some GMAT hopefuls
* This book is intended to be a guide for the general test taker, so be prepared to see mostly easy and medium difficulty problems. If aiming for a top score, you'll need to supplement your prep with harder material (such as LSAT sets for critical reasoning). As mentioned before though, do not neglect the easy stuff, since it gets you in the right mindset for the official style of questions. Besides, it's usually the very easy questions that throw off advanced students!
===== BOTTOM LINE =====
Official Guide for Review, 12th Edition is a must have, no matter your level. Even though you will have to spend some extra money on a good strategy book, getting the OG is crucial for your prep. As you go through various GMAT-related material, you will begin to notice the difference between an official question (clear-cut answers, great structure) and an unofficial question (structure is sometimes lacking, answers not as well defined). Because the "feel" of official questions is markedly different from that of test prep developed questions, I recommend saving/carefully reviewing some problems for the very last days before your test.
IMPORTANT NOTE: The 12th edition was released in the sprig of 2009 and contains roughly 300 new questions as compared to the previous, orange-color 11th edition of the OG. As such, if you already have the older version, it is not necessary to spend the extra money on the newer one. If you do have a choice between the two, go for the most recent edition; if not, the 11th is just as good.
Good luck on your GMAT prep!

The Official Guide for GMAT Review, 12th Edition is the only book on the market written by the creators of the GMAT exam. Inside you?ll find more than 800 actual GMAT questions from previous tests with answers and detailed explanations. There?s also a grammar review, math review, actual essay topics, sample responses, and scoring information insights into the GMAT exam that debunk test-taking myths. Plus, use the diagnostic section to pinpoint your skill level and focus on the areas where you need the most help. Top Myths About the GMATŪ Myth ? If I don?t score in the 90th percentile, I won?t get into any school I choose. Fact ? Very few people get very high scores. Fewer than 50 of the more than 200,000 people taking the GMAT test each year get a perfect score of 800. Thus, while you may be exceptionally capable, the odds are against your achieving a perfect score. Also, the GMAT test is just one piece of your application packet. Admissions officers use GMAT scores in conjunction with undergraduate records, application essays, interviews, letters of recommendation, and other information when deciding whom to accept into their programs. Myth ? Getting an easier question means I answered the last one wrong. Fact ? Getting an easier question does not necessarily mean you got the previous question wrong. To ensure that everyone receives the same content, the test selects a specific number of questions of each type. The test may call for your next question to be a relatively hard problem-solving item involving arithmetic operations. But, if there are no more relatively difficult problem-solving items involving arithmetic, you might be given an easier item. Most people are not skilled at estimating item difficulty, so don?t worry when taking the test or waste valuable time trying to determine the difficulty of the questions you are answering. Myth ? You need very advanced math skills to get a high GMAT score. Fact ? The math skills questions on the GMAT test are quite basic. The GMAT test only requires basic quantitative analytic skills. You should review the math skills (algebra, geometry, basic arithmetic) presented in both The Official Guide for GMATŪ Quantitative Review, 2nd Edition, and in The Official Guide for GMATŪ Review, 12th Edition, but the required skill level is low. The difficulty of GMAT Quantitative questions stems from the logic and analysis used to solve the problems and not the underlying math skills. Myth ? It is more important to respond correctly to the test questions than it is to finish the test. Fact ? There is a severe penalty for not completing the GMAT test. If you are stumped by a question, give it your best guess and move on. If you guess incorrectly, the computer program will likely give you an easier question, which you are likely to answer correctly, and the computer will rapidly return to giving you questions matched to your ability. If you don?t finish the test, your score will be reduced greatly. Failing to answer five verbal questions, for example, could reduce your score from the 91st percentile to the 77th percentile. Pacing is important. Myth ?The first 10 questions are critical and you should invest the most time on those. Fact ? All questions count. It is true that the computer-adaptive testing algorithm uses the first 10 questions to obtain an initial estimate of your ability; however, that is only an initial estimate. As you continue to answer questions, the algorithm self-corrects by computing an updated estimate on the basis of all the questions you have answered, and then administers items that are closely matched to this new estimate of your ability. Your final score is based on all your responses and considers the difficulty of all the questions you answered. Taking additional time on the first 10 questions will not game the system and can hurt your ability to finish the test. Myth ? I need to speak US English in order to do well on the GMAT. Fact- Essay grading is not affected by dialect of English. Questions on the GMAT are evaluated to ensure they are fair for all examinees, whether in the US or around the world.
