GMAT Official Guide OG 13th Edition (OG 13)

The Official Guide for GMAT Review | Best among GMAT Books

The Official Guide for GMAT Review 13th Edition (or GMAT OG 13) might be the single most important resource that you can have in your GMAT preparation process. Many call it the GMAT test prep Bible and not without reason. Among all the good (or bad) to best GMAT books available in the GMAT self-study market, the GMAT official Guide is the only book to include real GMAT questions for practice.

Most other GMAT coaching books create their own GMAT practice questions that mimic or are 'inspired' by the official GMAT guide.

Download Free GMAT Test Preparation Software

Along with the GMAT OG, you might want to download the free GMAT software - GMATPrep from MBA.com - to prepare and train for the test.

The GMATPrep software includes two full-length CATs (computer adaptive tests) that are a very good approximation of your GMAT score if you were to take it with your current level of practice and competence. It also comes with answers to each question, but unfortunately it does not include explanations of the underlying concepts.
