If you are searching for a review book or the AP Biology exam, look no further.. you need to buy this book right now!
I recently took the Biology exam and this book has helped me learn material I was not taught in class, or review material I had forgotten. What I like about this book is that every section was not overcrowded with information. All the chapters were short (6-40 pages about) and to the point. All of the topics were explained perfectly that I was never confused about what I was reading. The book comes with useful sample questions at the end of each section so you can test yourself, and the questions and explanations are very helpful. I actually saw one question from the review book on my AP Exam, so you know their information is reliable.
The one thing I did not like about this book was the lack of figures, or graphics. I am a visual learner and I would have preferred more descriptive pictures, such as the ones in my actual AP BIO textbook, to better understand concepts. The figures they had were vague.
Anyway, they did a great job at enlightening me about plants, a subject I did not learn in class but was prevalent on the exam. Please choose this book for its benefits are enormous and you are guaranteed a 4 or a 5 if you read this book in depth.
