To prepare for the GMAT, first familiarize yourself with the GMAT Computer-Adaptive Test (CAT) and its format (Chapter One). Next, study the different types of questions you'll face (Chapter Two) and take a diagnostic test to assess your current level (Chapter Three). Use this diagnostic to guide your study, focusing on weaker areas as identified. Finally, take the five sample GMAT tests provided (Chapters Nine through Thirteen) and review your performance to refine your preparation.
