GMAT Hacks Bookshelf

In the last two years, I've created a huge amount GMAT prep material. Many of you are already using it. I'm proud to say that thousands of students are working with my resources, and quite a few have let know just how effective they've been. One unique feature of my books is that they are sold as PDF files--you get them fast, they travel light, and they're much more easily searchable than paper books.

Total GMAT Math

This is my most popular book. (It was formerly known as "The GMAT Math Bible.") Clocking in at over 425 pages, it contains 300 realistic GMAT math problems and over 500 exercises, along with full explanations. Best of all, the book is broken down into about 40 chapters, each of which covers a single GMAT math topic in depth.

There's no better way to master GMAT math, whether you're just starting out or you're polishing your skills. Click here to read more and purchase.

Total GMAT Verbal

Here, I do for Verbal what Total GMAT Math did for the GMAT Quantitative section. This book (formerly known as "The GMAT Verbal Bible") covers every question type, breaking down the structures, topics, and patterns of GMAT Verbal. It also includes over 100 realistic practice questions.

GMAT Math Problems

I've created 18 sets of 100 problems each. (There's no overlap among the sets, or with Total GMAT Math!) Sets are available at different difficulty levels, and they cover every possible GMAT topic. You can get 100 problems of nothing but beginner-level number properties, or 100 problems of nothing but challenging Data Sufficiency questions.

Guides to the Official Guides

These were my first books. The Official Guides are great resources--these come straight from the testmaker, so you can't find more realistic practice in any other book on the market. However, the testmaker's explanations are not very instructive.

In these two books, I provide thorough, accessible explanations for every single math problem in The Official Guide and The Official Guide for Quantitative Review. Click here to find out more, or click here to buy one or both Guides at a discount with Total GMAT Math.
