Summary: An excellent book, perfectly complements the official guide
Review: This book offers some valuable tips and suggestions especially for cracking math. But overall it focuses more on the "Joe Blogg" tips and tricks approach, which may work for some people and not for others. I still believe knowing sincerely how to solve problems will get you far. But the PR book makes for an interesting read, gives you some excellent strategies (e.g., about the essay sections etc) and does the best job of introducing the concept of "difficulty level bins" -- which is how the CAT works. I, much to my surprise I admit, ended up with a 780 and for those about to take the GMAT, some tips: 1. Definitely get yourself the 'Official Guide' (published by ETS) -- that is indespensable. You should aim to complete it from cover to cover - it gives you a really good idea of the test questions though the math is a liitle easier than what I saw on the test. It even has a comprehensive, complete list of essay topics. 2. Practice tests -- my scores in Powerprep : 780,770; Kaplan : 670,650,690; Princeton : 750,720. So I'd venture to recommend this book to get a decent estimation of where you really stand, and therefore u must take the included tests seriously -- i.e., emulating the real testing conditions -- in order to get an accurate idea of your potential. Kaplan is really tough - I haven't seen too many folks scoring above 700 in thier tests - infact when i gave the first test straight after a 780 in powerprep and got a 650 I was pretty turned off - but later found out that it wasn't really a big deal. Get Kaplan for practice, but the PR and the official guide should be enough. 3. PREP BOOKS: Well other than the Official guide, I used PR and Kaplan. I found the math tips in Kaplan (50 of them) quite impressive but the practice tests in PR give you a very good idea of difficulty levels of math/analytic. This book lays out the test in "bins" (easy bin, medium bin, and the tough bin). I found this to be a very unique and useful feature. All in all, this particular book is superb for its purpose and complements the ETS OG fabulously. Highly recommended!

Review: Unless you are already on your way to a 700, this book should improve your score. I took the GMAT without reading it (just used the powerprep software. BAD IDEA) and did not do as well as I should have and will need to take it again to get the score I need. My wife bought the book a few months later and used it for her test. She was impressed so I took a look at it. a read a few chapters and picked out several items that would have improved my score. I imagine that once I have time to sit down and study through the entire book, I should be able to get the score I need.
