I looked through the review section a few times during the year but it wasn't helpful when I missed a lecture or when I didn't understand a homework problem. Quite simply, my class notes were a much better source.
I left plenty of time to take all six practice exams included in this book-however, because the exams in this book were unhelpful, I ended up taking only one of them. The multiple-choice questions are much more difficult than they are on the actual exam. The answer choices for the non-calculator portions of the multiple-choice are in decimal form. I just took out my calculator for the last step of changing the exact answer to a decimal approximation. However, this seems like an obvious error that should never have been allowed to go to publication. It's typical of the quality of REA's "best test prep" series.
The free-response questions are closer to free-response questions on the actual exam, but the free-response sections of the practice tests are not divided into calculator and non-calculator portions as they are on the actual exam. Besides, you can download real past AP Calculus AB free-response exam questions from the College Board's website for free, so I wouldn't recommend paying for the ones in this book.
I found the practice exams in the Apex Learning and the Arco books much more helpful, so I recommend either of those instead of this one. Do not waste your money on this book.
