content: Having tested many books that deal with the SAT I was positively surprised by the depth this book provided. The problem is the fact that the sample questions in it do not really reflect the real SAT-test and can only be used to study the math or the critical thinking skills.Also, dont plan to use this book to brush up your vocabulary - the included word-list provides you with only the meanings of the words and not with a sample sentence.This book might be suitable for usage in combination with 10 Real SATs or some other book that features more realistic SAT questions.
