Your Guide to The Official Guide

The Guide to the Official Guide is now updated to reflect the 12th edition of the Official Guide!

There's no better resource for GMAT Preparation than the set of books published by GMAC. They contain hundreds of practice questions written by the same folks who create test materials, so it's like practicing with real test questions.

But the Official Guide books are far from perfect. While they include explanations for every question, those explanations are also written by the people who write the questions. You can get great insight into the "official," "textbook" methods to answer questions. While it's important to learn some of those approaches, that isn't how you're going to rack up the most points on test day.

Finally, there's a solution for the Quantiative questions in the Official Guide.

I've created two booklets--one for the Quant questions in The Official Guide to GMAT Review, the other for The Official Guide to GMAT Quantitative Review ("The Green Book")–to fill the gap. Each one has over 100 pages of explanations. Not the technical stuff. Just the methods that will allow you complete questions efficiently and correctly.

There's more!

Each one of the booklets is chock-full of information about the questions it covers:

• Each math question is indexed by difficulty level. You can focus on, for instance, extremely difficult questions.
• Each question is indexed by content areas. You can now spend an entire practice session doing inequality questions, or word problems involving geometry.
• I recommend focusing on the 12th edition, but if you still have the 11th edition, I've included all of the explanations to the quantitative questions in the 11th edition ("The Orange Book") as well.

Most of all, you get cutting-edge strategies to help you answer every single type of math question the GMAT throws at you. This is valuable stuff: it's what I spend most of my time doing when I meet with my private clients. My explanations don't just teach you how to do the problem at hand, they show you how to attack an entire class of problems.

Best of all, when you decide you're ready to take your GMAT preparation to the next level, there's no waiting. Each of these 100+ page booklets are available as PDF files and sent to your e-mail inbox within 24 hours of purchase.
