As part of the Testing for the Public class that I’m taking I got a binder full of stuff and a copy of The Official Guide for GMAT Review. This is the book published by the creators of the GMAT test. It has a few hundred retired practice questions taken from actual previous GMAT exams. This book is well over 800 pages of practice material and explanations.
