most of the stuff in this book is already in the GMAT official guide(OG 11) except the practice problems. buy this book if you want more math practice...it has good amount of practice problems: Problem Solving(176), Data Sufficiency(118)
and these problems are different from the ones in OG 11.

It has been seven years since I have been out of college. My math skills are very rusty. The Quanative Review is the best book to get because it is written by the GMAT Staff. Each question comes with an explanation of how the problem is solved. The book is broken down into sections with complete explanations.

I am not good at math at all and there are over 300 problems to solve from basic arthimatic, algebra, geometry, and Data Sufficienty. all have multiple choice answers and at the end of each section.

The book is much cheaper than getting it through the mba.

I also recommend the GMAT Verbal Review as well

This book is a must if you are about to take the GMAT and need lots of practice on Math it contains a lot of good exercies and how to solve them...

I have been studying for GMAT for a few weeks now and I think the OG is a great source for a good practice on real GMAT questions. But having said that, use the OG only once you grasp all the basics and when you are almost ready to take the GMAT. The OG does not contain any math conceptual content, so use it only for practice towards the end.

In order to get a real GMAT prep - I would recommend you buy the set of 9 books of "EZ Solutions," or whichever book(s) you think you need most help with. These books are very detailed oriented and cover everything on the GMAT math. First use the review modules to get the concepts and then use the workbooks for practice. Some of the most challenging topics in GMAT math, such as permutation/combination, probability, geometry problems, complex word problems, etc., are brilliantly explained in these books. Also, the EZ Advanced Workbook is a "must have" if you are aiming for a high score. It may be a good idea to buy Barron's without the CD (don't waste money on the CD version for any book). After doing all this, use the OG and you will see a dramatic difference in your scores. If you still need more practice, you may consider buying the Kaplan book (but really not needed). Save your money by not buying anything else. You don't even have to take any of those pricy courses. I followed this process and my scores have jumped from the 500-range to the 700-range. Good luck!

This book is just a copy of one part of "The Official Guide for GMAT Review, 11th Edition". If you buy that then you shouldn't be buying this book. It is just a waste of money.

After going through all the GMAT books, here is my honest opinion about some of the most popular GMAT books:

Official Guide:
Pros - Excellent source of GMAT questions. Very well organized with real test like questions.
Cons - No review of any math content or test-taking strategies. Not enough explanations of practice questions.
Overall, the Official Guide is a must have for all test-takers. It will give you a good idea about the type of questions to expect on the GMAT; however, if you need more than just a bank of questions, you need to look at some other source.

Kaplan:
Pros - Good for additional practice questions as a supplement
Cons - Review of math content is not thorough but just the very basics. Not enough explanation of test taking strategies. Full of guessing techniques with no real mathematical solutions. Not good enough explanations of practice questions. Unrealistic questions.

Princeton:
Pros - Good for additional practice questions as a supplement
Cons - Review of math content is not thorough but just the very basics. Not enough explanation of test taking strategies. Full of guessing techniques with no real mathematical solutions. Not good enough explanations of practice questions. Weird sense of humor.

Barrons:
Pros - Good math review. Big list of questions. Good test taking strategies. Very well organized. This is by far the best of the all-in-one kinds of books.
Cons - Although the book has a good math review, it doesn't go deep enough into each concept. Not enough explanations to practice questions. Does not have a good section for logical reasoning (permutation, combination, probability, etc) questions, which is one of the most important question-type. Does not break down the concepts/questions step by step.

EZ Solutions (set of 9 books):
Pros - Thorough math review from A to Z. Effective test taking strategies. Abundant solved examples. Numerous practice exercises. Great practice question bank in basic and advanced workbooks.
As with most books, you are expected to already have a good knowledge about the various match concepts, but with these books, you can literally start from scratch and reach the most advanced level of the GMAT.
Cons - To get the best result from these books, you have to invest in buying several books (set of 9 books), but if you compare the cost and benefits, the benefits outweigh the cost, or you can buy a few not all. Missing the verbal section. This is not a good option if you are looking for a mediocre score or just looking for a very basic brush-up. Recommended for serious test takers only.

Some of the popular books (wont take any names here): Not even sure what is in these books. They have nothing, no content, no concepts, no strategies, no real questions, just a guide to refer you to the OG.
Others - There are some other not so popular GMAT books but I haven't yet had an opportunity to review them, may be some of them are good supplementary aids.

I hope my review will help some of you in making the right decision.

I hope my review will help some of you in making the right decision.

I received this book very quickly and was able to raise my score 200 pts.

Received the product quickly and in reasonably good shape (no thank to the USPS)
I also have the the bigger GMAT study guide. The combination has really helped me to get in the groove of what type of questions I can expect.
If you have test anxiety, don't do the guide!! Take the class. This will only help you if you just need the exposure to test questions. If you freak out at tests, take the class so you get the total experience.

but i do not encounter any problems from this book in the test at all.

The questions I thought were really basic atleast the first 100. There are only a few tricky ones. It might give a false sense of expertise in GMAT math. But if you are looking for just practice it gives the range of questions.

While I did not compare this with other guide books, as some reviewers have, I did use it to prepare for the GMAT. There are tons of questions, their answers and explanations for the answers. There is also a good section on how to approach the analytical writing section of the GMAT. This book complements the Official guide 11th edition.

If I were to have to take the GMAT again, I would buy this book again.

I scored 90% Overall.

You should definitely make this a part of your study plan. The book was extremely helpful to me. I found it to be an excellent refresher. The explanations in the answers were great.

While I did not compare this with other guide books, like some reviewers have, I did use it to prepare for the GMAT. There are hundreds of sample problems and the solutions and HOW the solution was arrived at.

When I took the exam, there were no problems that were in a format I had not seen. Naturally, they were different, but the TYPES of problems had all been explained in the book.

If - for some insane reason - I were to have to take the GMAT again, I would buy this book again.

PS: I scored 90% on the quantitative (woohoo!)

The GMAT Official Guide is a great book for practicing GMAT questions, it offers a little bit of all types of questions. This book is especially good for starters, but the major drawback is that it doesn't offer too much of mathematical review or strategies.

Luckily, i bought the "EZ GMAT - Math Strategies" book along with this book. It helped me a lot by applying the math strategies given in the EZ GMAT book to the question in the Official Guide. You may also consider buying the GMAT Official Quant book.

The questions in this book are definitely A LOT easier than their counterparts from the Official Guide for GMAT Review. Nevertheless, I was still surprised when I got a total of 10 wrong answers. This book by itself is not enough for GMAT study, but it is great for warming up before working on the questions in the official guide.

This difficulty level of this book is definitely not as high as that of the Official Guide For GMAT Review. Nevertheless, I still recommend this book as a "warm up" before moving on to the official guide. To me, practice solving old exam questions always helps regardless of the difficulty level.

The best GMAT book to study quantitative. It gives shortcuts to do the problems, the types of problems GMAT will ask you and many exercices

I bought this book in addition to the Official Guide and the Verbal Guide. While it does have additional math problems, they are lacking in complexity and not representative of what you will see if you're scoring much above 600. I found the problems in the Official Guide much more representative of what I faced on the GMAT. So, if you're scoring at a high level, skip this book and concentrate on the last 50 problems of each math section in the Official Guide.

I bought this book with the understanding that it was not a study guide. This book should be only used as an additional aid for the math section of the GMAT. This book has really great sample questions that are very similar to the questions that you will see when you take the GMAT. This booked coupled with a GMAT Review study guide, such as the books offered by the Princeton Review makes an awesome combo.

This book is very good if you only need to review the math part for the GMAT. I would recommend for a few more dollars to get the bigger book that covers all sections. It has the same amount of math questions as the Analytical one has.

This book is slimmer than the orange Official Guide, weighing in at about 300 problems, but if you need more math practice, it's a great resource. One caveat: the average difficulty level of questions in this book is somewhat lower than that of the questions in the Official Guide. If you're already getting a 650 or better on practice tests, or if you are comfortable with the vast majority of math problems in the Official Guide, go ahead and skip this one. If you're not yet at that level, this is an excellent supplement to the orange book.

It can't be emphasized enough the importance of doing "authentic" practice questions: while some test-prep companies are better than others, none have completely mastered the exact tone and nature of GMAT questions. As these questions are written by the same folks who write the test, you can't really improve on the authenticity.

The Quant Review book does have some actual math "review" material, but it's very official in nature. Not a shortcut in sight. Buy it for the questions; read the review if you're stuck in the subway without a pencil and scratch paper.

This is an excellent book with the real GMAT questions. It explains all the questions and answers and also explain why a particular answer is correct. Till now, this is the best GMAT practice book I've seen. Anyone preparing for GMAT needs to have this book

This book is a quick way to jam through some GMAT practice math questions, nothing more and nothing less. I sat down and did it in a weekend without too much effort. I agree with other reviews that this book is not a good place to begin your studying in that there aren't many pages devoted to concepts - it really is just a tool for practice. As mentioned in other reviews, the questions are in order of difficulty. I found this useful because it gives you a very clear sense of what the GMAT considers difficult versus the types of questions that are considered easy. If you're like me, you'll zip through the bulk of the questions and then hit a wall where you notice you're getting more and more wrong - a good thing, while you're still studying! Kaplan questions are generally harder than these, Princeton Review a bit easier, and Barron's are just plain bizarre. Given the huge inconsistency across books - it's nice to ground yourself in "official" questions once in awhile.

I bought this after going through the 2005 Kaplan GMAT book. The pro's are that it has a lot of actual past math questions (176 problem solving & 118 Data Sufficiency) and they are very similar to the type of question you will encounter on the real test because the book is by GMAC (the makers of the actual GMAT test). Therefore, it's great as a source for additional practice. The con's are that it has a very brief instructional section that isn't very useful at all and the problems are organized in order of increasing difficulty. This means that approximately the last 20 questions of both P/S and D/S type problems will be like the real thing, assuming you are doing fairly well on the real thing and only receiving difficult level questions. All in all, I highly recommend using this in conjunction with another more thorough GMAT review (such as Kaplan), but not on its own. And if you want an accurate full-length practice test then definitely use the 2 FREE practice tests downloadable from MBA.com when you register to take the GMAT - they are much better indicators of actual performance than Kaplan.

Contrary to the information at some MBA chat sites, the questions in the two supplements, The Official Guide for GMAT Verbal Review and The Official Guide for GMAT Quantitative Review, and the main volume, The Official Guide for GMAT Review, are largely carried over from the 10th edition and the PDFs of retired exams sold by MBA.com. So if you have the 10th, you won't get as much as you might hope from spending for the new main volume, or $17 a pop for the supplements. You will get what GMAT calls "improved" explanations. Improved? They do seem more detailed and better organized. These books are good study tools, just not as new as the GMAT folks would like us to believe.
