too many typos and mistakes
Can't believe there are so many typos and mathematical mistakes in this OFFICIAL guide. If you have a weak mathematics background, you will be definitely confused or misled.

I love this book. People are saying that the questions in this one and the verbal and math supplements books are the same so I went to Barnes and compared the reading comp sections and all passages were different. So...I don't know if they're comparing with the 10th edition or they're on something. If you're studying for the GMAT, at least get this book. It has a gang of questions from actual exams which is great for the verbal section because I would think verbal questions are harder to mimic than math questions.

AT LEAST PURCHASE THIS BOOK OR THE SUPPLEMENTS.

Manhattan books seem good too. I'll be ordering them within this month.

Lousy Quantitative Section/No Tips or Strategies
This book stinks. It has a VERY limited review of the concepts covered in the math section of the GMAT and absolutely no strategies on how to get a high score on the test.

If you're rusty in high school level math, you're going need a serious review, which this book does not provide.

This book is mearly a catelog of old GMAT questions for the user to practice with.

Best of the GMAT review options
I went through this book, the Kaplan book, and the Princeton Review. This is by far the best of the 3. It has the most review questions and doesn't try to teach you any garbage strategies, just how to do the questions. The one shortfall is that the answer explanations are sometimes not in depth enough.

Good for biginners
I just want to give some advice before you buy the book.
First, The problems are way too easy compared to Kaplan. I bought Kaplan Before buying this review, and the problems overall are way harder in Kaplan.

Second, If you don't know what the GMAT is all about, I highly recommend the Official Guide. After you finish this book go on an do Kaplan, and I will guarantee you a good score in your GMAT.
