The Princeton Review realizes acing the SAT is very different from getting straight A's in school. They don't try to teach you everything there is to know about math and English - only the techniques you'll need to score higher on the exam. There's a big difference. In Cracking the SAT, they teach you how to think like the test writers and:
Eliminate answer choices that look right but are planted to fool you
Master the 250 most important vocabulary words for the SAT
Nail ever the toughest sections: Analogies, Quantitative Comparison, Critical Reading, and more
This book includes 3 full-length practice SAT exams plus they will show you how to go online and take additional exams with instant score analysis. All of the sample test questions are just like the ones you'll see in the actual SAT, and they fully explain every solution.
