The mission of this book is to clarify all the necessary CONCEPTS a student needs to ace the SAT WRITING. This book is composed of 10 full length SAT WRITING exams. The tests in the book are neither easy nor hard, but they can be tricky. However, the test’s Question explanations are designed very descriptively so that a student can learn easily. Our recommendation is that a student should complete each test at least twice: first for learning purposes and second for testing purposes. To the author’s best belief, if anyone finishes this book at least twice and understands all the TOPICS and their CONCEPTS very well, he or she will get a lot of benefits.
