A good way to practice, but not to study...
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 found this to be VERY helpful
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!)

Fairly useful
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.

Not All New, But Not Bad Either
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.
