<p>What are the best prep books if you're self-studying without a textbook?
I.e., when I self-studied Bio, I used only CliffsAP 3rd ed. (and a website for the labs) and I got a 5. I'm particularly interested in the following subjects:</p>
<p>Stat
Psych
Comp Sci
Calc BC (w/ AB class)
Enviro
Human Geo</p>
<p>Thank you in advance :)</p>
<p>Stat - Cliffs is great, don’t know about others
Calc BC - any and all are more than adequate for a perfect score (108/108) on the AP test if you know what you’re doing</p>
<p>Edit: barron’s is good for stat too, i used that as well</p>
<p>I can only speak for two of those exams, but I can assure you that I checked out every review book my library had available for both Stat and Calc (Barron’s, Kaplan, PR, REA, etc.) and I found these to be the best:</p>
<p>Stat - REA (This book covers everything on the exam condensed into chapters that are very easy to follow. It has very helpful instructions for the calculator as well.)</p>
<p>Calc BC - Princeton Review (MC are good practice and model the exam closely. The review sections are excellent and really break down all of the subjects well. Study the AP Central FRQs in addition to PR and you’ll be set.)</p>
<p>Enviro- PR or Barron’s (I used PR and liked it, others say the same about Barron’s)</p>
<p>HumGeo- Princeton Review. I feel it helped most for this year’s exam that I recently took. You may want to get Barron’s too.</p>
