<p>i only need one or two for each subject and id prefer less review and more questions/tests...</p>
<p>APUSH most practice tests is REA regular book, not the crash course
AP Bio - stick to Cliff's, do the question at the end of each chapter; also try Princeton Review; don't think Barron's is good</p>
<p>5 Steps to a 5 is really good for Bio. Also, try Amsco's AP Biology. The questions are a lot harder than both Cliffs and 5 Steps to a 5. i have all three --> can never be too prepared.</p>
<p>For APUSH REA is the best, but 5 Steps to a 5 is always good.</p>
<p>AMSCO is the best for APUS, but i heard REA is also very good. </p>
<p>For Bio, Cliffs and 5 Steps to a 5 are the best.</p>
