I've bought this book because of the high reputation Barrons has maintained in the SATs world. I recently took the June 01 Physics SAT II, and I now reflect. This book does cover most topics in detail; however, it fails to provide accurate model exams. Because the College Board has never released any copies of SAT II physics exams, Barrons was forced to put together the tests and the book blindly. Anyway, I read this book three times thoroughly and I have an A average in physics at school. This book is a big disappointment for this subject test.In fact, I went to [a store] the next day to see if any other prep book had an accurate model exam. Guess what? I found the Princeton Review book so accurate that it had about 14 similar questions from the test. So, buyers beware. Don't buy this book because you'll just screw up a SAT score. For this subject, buy the Princeton Review version. But, for biology and chemistry, use Kaplan.
