This book sums up AP Biology in about 75 pages, thats amazing. The practice exams are what counts. Im a student but for teachers this book can be of great use if bought with the CD-ROM. You can install it the media center and have the students take the three practice exams before the real test. It times you and gives you a raw score in the end. Has descriptive answers to all of the questions as well. But as for just a review book-no.
