Kaplan's new Source series helps individuals learn how to approach and conquer common concepts in grammar, math, vocabulary, and writing by using Kaplan's exclusive Building-Block Method. This method focuses on mastering the basic principles in each category through focused practice-based learning that attacks each concept from all sides. Readers will use different forms of integrated learning to master each concept and retain what they've learned. Each book is written in a fun, conversational tone and features: * A ten-question diagnostic quiz to show readers where they need the most help * Topics broken down by subject to help readers group concepts together for easier memorization * Material commonly found on standardized tests like the SAT and GMAT * Examples of how each concept can be used in everyday life * Recognition and recall practice exercises at the end of each chapter * Detailed answer explanations * A summary of key points at the end of each chapter * Plus: Kaplan is sponsoring a contest where readers can explain how the Source book they used changed their life; the best story for each book will win a set of Paramount DVDs.
