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 GMAT®
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 GMAT® Quantitative Review, 2nd Edition, and in The Official Guide for GMAT® 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.

WE LIKE THE QUESTIONS: Like previous editions, the 12th edition of The Official Guide for GMAT Review (OG12) contains hundreds of actual questions from past GMAT tests. The questions cover all areas of the GMAT and provide tremendous insight into what the GMAT is after. We are slightly disappointed that OG12 dropped some great questions on prime numbers and factorization that were included in OG11, but overall we find that as a source of practice questions, the OG12 surpasses any third-party material that we have come across.
WE DO NOT LIKE THE ANSWER EXPLANATIONS: Though not incorrect, the answer explanations do not necessarily help the reader learn how to answer a question within two minutes, the average time per question allowed by the GMAT. We consider this to be a very serious flaw. Consider, for example, Question 10 on page 21, and its answer on page 50. Reading the explanation alone can consume more than five minutes (unless you read 10-variable math equations and their solution like an English novel). But wait! You are supposed to solve the entire problem in two minutes! There has to be a better approach, and actually there is. It would be nice if the GMAC addressed this deficiency in the next edition.
A CAVEAT ON THE SO-CALLED DIAGNOSTIC TEST (pages 20-44): If you are just starting on GMAT preparation, you might want to skip the Diagnostic Test at the beginning of this book. The questions are tough, and the results may leave you feeling demoralized. You would be better off circling back to the Diagnostic after you have gone through the other 700+ questions in the book.
BOTTOM LINE: As a source of excellent GMAT questions, this book is hard to beat. Buy it for the questions, but be prepared to be disappointed with the explanations.
I strongly recommend that you download the two practice prep tests from the GMAT website [...] The scores you get on these two tests will be very similar to what you get on the actual GMAT. In fact, the score that I got on the second prep test was identical to the score that I got on the actual GMAT. Practice these prep tests over and over so you get an idea of how to pace yourself and what types of questions to expect. Try doing the entire prep test including the essay sections just like you are taking the actual GMAT. The GMAT is a long test and you might find yourself losing stamina towards the end. So practice the full prep tests until you feel comfortable doing the entire test. You may also want to switch out the two essays from each prep test with essays from the Official Guide. Although the math and verbal questions can change (especially when you start to get higher scores), the two essays questions remained the same. I only wish they had more prep tests to practice with.
Regarding the sample computer tests (two of them) that you get from [...], as the other reviewer said, please do not waste them. My two scores were 20 points apart and my actual score was right in the middle!
Finally on AWA, if you care, there are some templates out there on some web sites and this is a good starting point, you don't have to copy it exactly but it will give you a good idea on how to structure your essays.
Now that I am done, I have to figure out how to get rid of these books :-)
Top reviews from other countries
Number of Question in each sections are
Problem Solving : 230
Data Sufficiency : 174
Reading Comprehension : 139
Critical Reasoning : 124
Sentence Correction : 140
And there is one Diagnostic Test as well so 100 more questions.
Please Note if you already have The Official Guide for GMAT Review 11 then there are only 200 questions are different in this editions.
Following points about this book.
1. This gives you real taste of real GMAT questions.
2. But this book is not for building your basics or concepts for that you should buy some other book such as Manhattan GMAT, Set of 8 Strategy Guides .
3. Along with this book try OG verbal and OG quantitative.
4. Problem in this book comes with clear explanation why one choice is right and why others are wrong.
I find the paper quality of this book is not very good paper are very thin.
Overall if you are serious about GMAT this is best place to start, and you need lots of practice.
