Official Guide, as the name suggests, is an official collection of retired GMAT questions, published by GMAC, who own GMAT. Here, I will review this book and its importance in the overall preparation. First, I was short on time in preparing for GMAT and applying in time. So, I didn't had time to go over all the material and guides available in this universe, and then compare and review them. Second, before you start your preparation, or make your plan, you need to understand what GMAT is and what... more info
Poor preparation material:
This book begins by stating that it is virtually all you will need in order to score well on the GMAT. I went through the book backwards and forwards - again and again and again.

USEFUL FOR BEGINNERS!:
This book is very good for people who wuold like to start their preparation for the GMAT. You have enough exercices and and a useful section (explanations) about math, algebra and geometry.
After, if you need a more brilliant preparation you need to practice on GMAT 800.
I'm Italian and when I started to read GMAT 800 (by KEPLAN) I found it harder (contents and language).
so-so:
I wasnt totally happy w/ this book. As other readers have posted there are countless errors in the math sections. For example on page 335 of the 11th edition they say (xr)^2 = x^(2r). This is hard to look over as a typo - as are other errors. There are also no full-length exams in this book. I mean, come-on, why are the GMAC guys such tight-wads with their questions. I dont really like they way they run the show...
