This book is designed to help improve students' GMAT scores without the need to memorize numerous mathematical theorems or complex grammar rules. The primary focus of this book is on a limited but crucial set of key concepts essential for success on the test. Standardized tests like the GMAT not only assess verbal and mathematical skills but also attempt to evaluate a person's intellectual abilities (IQ) through a series of potentially misleading tricks. This book provides specific techniques for tackling these tricks, which are useful not only for the GMAT but also for other standardized tests.
