Do You Know Any "Smaller" Biology Textbook? (for AP Biology)?

<p>Hi, I am currently taking AP Bio class. Like in general, I read Campbell Biology textbook but having trouble with catching the information. I decided to get another textbook that is smaller in details and more focused on the basic idea/summary (textbook that summarize the big textbook like Campbell). I have Pearson's AP Bio Prep Series, Barron's, Princeton Review, and Cliff notes; however, I feel like I need another textbook that focus on the main idea and little detail. Do you know any such "smaller" biology textbook??</p>
