Test Preparation AP Sciences

<p>Hello.
I bought several AP Biology prep books, but really regrets it and try to choose few and return others to the bookstore. Right now my plan is that:</p>

<p>Cliff Notes
Student Study Guide for Campbell Biology / Barron’s
Princeton Review / REA Crash Course
Barron’s & McGraw Hill & Princeton Review AP Bio Flash cards / Oxford Dictionary of Biology
CB Released Exams (2) / 5 Practice Exams (Cliff Notes) / Sparknotes Powerpack
CB Lab Manual</p>

<p>For each slash (/) part, what 1 prep book will you choose?</p>

<p>Cliff Notes is a good book. My brother who went for an AP biology school course said that the prep books that I had and he bought (5 Steps and PR) were pretty much useless since they weren’t in-depth enough.</p>

<p>He used Campbell only. Nothing else, not even the student study guide.</p>

<p>Are “5 Steps to a 5” amd “Princeton Review” are not really good? What about REA & Crash Course?</p>
