<p>Can anyone please tell me the best prepbook for AP Environmental Science?Kaplan?Barrons?</p>
<p>I heard that if your taking ap biology and study from the cliffs then you can pretty much get a descent score, so i think cliffs is the best or go princeton review.</p>
<p>Barrons - only use if you have enough time to study or are self-studying
Princeton- short and sweet</p>
