GMAC's GMAT 13th Edition Review: The only Study Guide by the Creators of the Test: The Official Guide
The Official Guide to the GMAT, thirteenth edition will be the only guide on the market that contains official questions from the new Integrated Reasoning component being fully integrated into the test in June 2012. Because this component is more interactive than other core Components
in the GMAT exam (Verbal, Quantitative and Analytical Writing), the Integrated Reasoning practice questions are housed on a companion website that Readers
will be able to access after purchasing the book. In addition, 20 percent of the current questions are replaced all with official questions used on actual GMAT exams. No other GMAT study guide can provide this. This book is the only guide on the market to include study information and practice questions written by the writers of the test.
