Query: Not the best study aide

I bought some REA's books like AP US history, and i liked it because of its indept review of EVERYTHING, however i was very dissapointed in this book of AP biology. This book doesnt give in-depth review of Biology concepts for the exam. It is very brief and covers the whole concepts in less than 100 pages. Not the best review, and their practice questions arent that great neither, i recommend Cliffs AP, or Princeton Review.
