<p>Hi, I am currently studying for AP Bio. Our school's AP Bio class is one year.
I found myself not really retaining information from Campbell Biology 8th Edition. When I study with prep books only, I make a better grade in quizzes and tests in the class. I decided to not read Campbell Biology but read my prep books. I use:</p>
<p>Cliff Notes, Barron's, Pearson AP Biology Prep Series: Biology by Holtzclaw, Princeton Review, 5 Steps to a 5, AP Bio Lab Manual by CB, and Sparknotes' Chart. </p>
<p>Should I use those prep books mentioned above if I make better grade by using them than Campbell Bio?</p>
<p>Also, I plan to buy "Biology: Concept and Connection (by Campbell)" and study along with prep books, do you think it will help?</p>
<p>Thanks in Advance!</p>
