The Official Guide for GMAT Quantitative Review, 2nd Edition

There are a lot of books out there trying to sell their special methods for the GMAT - often written by the very schools (Princeton Review, Kaplan etc.) that are trying to sell you their $3000 prep class. The truth is you don't need those because 1) they don't feature actual questions from the GMAT 2) the purported "special strategies" are nothing special at all, often just a re-writing of the strategies already spelled out in the official GMAC preparation material 3) they are often written in a completely dumbed-down language (which most people will find highly irritable). In short, the official GMAC practice book has all your need to prepare for the GMAT and will suffice for the vast majority of candidates. It has a great review section explained in straight language, and a long list of actual questions from the GMAT exam. Buy this one (and the verbal version). Don't waste money and time on the other books.

Great study books, better than any other I've checked out. If you go through the Official Guide, the Verbal, and the Quantitative books cover to cover, there's no way you won't be prepared. No need for any other books or expensive classes. Each question has a very clear, descriptive solution explained. Best, cheapest way to get a good score on the GMAT.

Pro's of this book: - All the questions in this book are OFFICIAL GMAT questions, written by the GMAC company. This is the greatest advantage of this book: It allows you to get used to GMAC's specific style and topics covered. Note that books such as Princeton Review, Kaplan, Manhattan, etc, are definitely helpful, but do not always perfectly replicate GMAC's style. - Lots of practice questions: More than 300 problems, about half of which are problem-solving and half of which are data sufficiency. Great for quant practice. - Explanations are decent. Maybe not sufficiently simplified and detailed if you are just starting out and have forgotten how to, say, multiply fractions and do basic algebra. But after having reviewed math basics (using MGMAT, Veritas, or other), the explanations are generally sufficient to understand where you went wrong. - The questions are relatively easy, so its great for the first 1-2 months of studying for the GMAT and building a strong quantitative foundation. - The paper is good (Unlike Princeton Review!) - The layout is perfect. You can choose whether to work in the section without explanations (for ex: if you are timing yourself on a batch of questions at a time), or to work in the "explanation" section, so you immediately have the explanations in front of you. Note that the "explanation" section also lists the original problems, so no need to keep flipping back and forth between problem and explanation! - Its not expensive Con's of this book: - The "math review" at the beginning is NO WHERE NEAR SUFFICIENT to cover all the tested topics. Thus you will NEED to supplement with additional quantitative strategy guides from other companies if you are aiming for a high score and/or have a weak quantitative skill level. I would recommend the 5 MGMAT quant series. - The book lacks challenge questions. Its great for practice in the first 1-2 months of studying and building a strong quant foundation. HOWEVER, if you are aiming for a high score (+Q40), this book alone will not get you there. Overall, A MUST HAVE for (1) weak quant scorers (2) building a strong quant foundation in the first 1-2 months of study and (3) getting used to GMAC's style. However, before using this book, you should review math basics using strategy guides such as MGMAT, in order to feel more comfortable with the explanations. Also, to get a high score, you will need to find another source for more challenging problems.

When i searched about GMAT from internet after i decided to take this exam, many says that people should stick with the official guide blah blah blah. I did not follow that rule until recently. After purchasing and reviewing the book, i thought, man! i should have done that earlier. Here i am again telling you ... stick with the official guide book which is far better organized and explained. I mean, there are several subjects (in math) that is not covered on my previous unofficial gmat books. Plus when correct answer is explained, it always include the original question itself, which was helpful (i dont have to turn pages again and again searching what was the question like etc.) Overall great book, i am happy with my purchase and i got my books just in a few days.

I bought this book as I had already worked through all the PS and most of the DS in the OG13 but my quant wasn't as high as I needed it to be. This book is great in that if offers what? 200 more problems in each section? The more you work through, the better, obviously. However, many of the answer explanations are incredibly vague and useless. Luckily, there are websites/videos that testtakers like you and me post online where they actually work through the problems step-by-step. I still recommend this though, as these types of questions are what the makers of the GMAT will ask, so it's good to be familiar.

I ordered this for some extra help on the quantitative review. The free GMAT test prep software is good to see where you are and get some practice with the timing, but the software's math review is not that great. This guide gives you plenty of practice problems, and answer explanations so you can see where you made your mistakes. It helped me improve my Quantitative score significantly.

This is one of two GMAT prep books I think is a must-buy for anyone. If you are struggling conceptually, this won't necessarily help, but you'll be able to diagnose weaknesses and do a ton of problems that will help you get the problem solving process down.

Use this as a good backup with Manhattan Prep books to get a high score. It will take a while (est. time; 6 months part-time) but it's the most comprehensive method to get ready for the GMAT.

Sehr hilfreich als Ergänzung zum Official Guide oder dem Kaplan Buch, weitgehend neue Aufgaben, eigent sich aber nicht als einzigstes Vorbereitungsbuch

The book is really good with great content at this price range.

Great!

This OG guide is a good one that is fundamental for everyboday preparing for the GMAT. It is good value for money

【高評価したい点】 ・問題の内容などは非常によい。過去問というせいも勿論だが。 ・解き方や説明などが細かい。 【低評価したい点】 ・別に低評価したいということではないが、解説も含めすべて英語。というより洋書だから当たり前ではあるが。 ・TOEICでなら750点ぐらいの英語力がないと、ついていけないでしょう。 ここからは完全に低評価したいところである。 ・この値段で300問しかないのはいささかCPが悪い。 ・問題数がやや少ない上に、レベルもそれほど高くない問題が多い。よって中・上級者にもちょっと不満が残るかもしれない。
