Choosing AP Biology Prep Books...SOS!!

<p>Hello, I am a high school sophomore taking AP Biology class. We use Campbell Biology 8th edition, and I also bought Cliffs AP Biology. I strongly feel that I should purchase 2 more prep books to cover the materials each prep book missed.</p>

<p>I am trying to buy either a set of Barron's and Princeton Review or 5 steps to a 5 and Peterson's. Which set is better, and also match with Cliffs AP Biology?<br>
Among Barron's, Princeton Review, 5 steps to a 5, and Peterson's, which AP Bio prep book do you recommend?</p>

<p>Thank you!</p>

<p>Barron’s as a sceond choice</p>

<p>i agree. cliffsnotes is good, barron’s a good second choice.</p>

<p>Cliffs has the best prep book for AP Bio. It’s all you need. I’d use PR or Barrons as a second choice.</p>
