The Official Guide to the GMAT, 13th 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 will be housed on a companion website that readers will be able to access after purchasing the book. In addition, 20% of the current questions will be replaced - all with official questions used on actual GMAT exams. No other GMAT study guide can provide this. The book will publish three months before the new test is integrated and will be the only guide on the market to include study information and practice questions written by the writers of the test.
