good book for GMAT
Basically I use this book to enhance my reading skill and writing skill because I am writing my dissertation. Although I read academic journal almost every day, when it comes to writing it becomes difficult. This book can help me to organize complicated sentences.

A must have!
You must get this guide book if you want to prep for GMAT. While it doesn't cover strategy or the AWA section it does give you lots of great practice! I ended up with an 89% ranking on the verbal section thanks to this guide.

Have not received!
I have yet to receive the book after more than one month since the purchase date.
Could someone tell me why?!?

Must Have Book For GMAT Preparation
This book is an excellent book, no doubt about it. It is a must have book. I have yet to take my GMAT test but I do know this book is very helpful in my preparation. I especially admire the answer reviews b/c every question is explained in great details. Basically the book teaches you the tricks about each question and every given answer.

Not a good book
If you already have the Official Guide for GMAT review, then this book is not worth the money.
All the questions have been picked from the Official guide for GMAT review. So if you already have the GMAT review then this book has nothing additional.
