Math SAT 800: How to Master the Toughest Problems contains 425 math SAT problems suited for students who have already taken the SAT or PSAT (or at least a practice SAT test). This book is most appropriate for students who scored 550-600 or above out of a possible score of 800 on the math portion of the SAT.
The chapters in this book will provide ample opportunity to practice only the most difficult problems found on the SAT, rated a 4 or a 5 out of 5 on the Education Testing Service scale of difficulty. The goal of this book is to maximize your score by zeroing in on the most difficult problems that appear on the math section of the SAT exam. This book differs from other SAT books in that it doesn’t spend time on material that high achieving math students are already familiar with. Therefore, this book provides the most efficient way for advanced students to study for the math SAT.

Fantastic book!
Amazon review from S. Becker
"As a high school teacher of a rigorous college preparatory course, I am always looking for the latest, best, and highest quality SAT prep materials available. I have read and used all the other books out there from all the different companies, and in my opinion, this one is extremely user-friendly (well-organized and clear explanations), relevant (covers the problems students need to know), and overall, a great tool for high-achieving students. It is a great value for what you get. I am excited to use it in the classroom and highly recommend it."
