Lots of useful practice problems
Amazon review from Frankie B.
"Good book if you're looking for 'medium' and 'hard' type problems to practice for the SAT, which make the difference between getting a 600-700 and getting an 800. You don't have to waste time solving the easy problems that you already know how to do.
The book is divided into 11 sections, so you can focus on the type of problems you want. Also, there are two practice exams with a mix of all different kinds of problems. And you can look up the answers and detailed explanations to every problem at the back of each section/exam."
