Recommendations on prep books for my classes please?

<p>I've already gotten 2...
Barron's for AP Calculus
Cliffs for AP Biology</p>

<p>Are these both good? Haven't really looked through them yet.</p>

<p>And my remaining classes are AP Stats, AP Environmental, and AP World History.</p>

<p>I searched through CC and found that both Barron's and Princeton are good for the WHAP. Which one do you think is the better buy to just read through in conjunction with taking the class? My teacher also told me that Barron's and Princeton are both acceptable, but I want the better one..
As for AP Stats and AP Environmental, I figured I don't really need prep books, as these are easy classes :P Why waste money?</p>

<p>Never mind; after searching some similar threads, decided to go with Princeton.</p>

<p>Hey PR is good for ap calc but they put way easier FRQs than the real exam. I used The past FRQs online for studying, it was better than most prep books. PR is perfect for MC portion though. Good luck</p>

<p>APES - PR. I used it this year and it was super helpful and easy to read. It covers pretty much all the topics and all major acts and laws</p>

<p>AP World - PR. ALso used this year and it I think I owe my 5 to this book and the amount of work I put inoto it. It covers everything you need to know. I actually started using Barron’s at firt and it wasn’t bad, but I felt that there was a little to much info that we didn’t need to know and I didn’t like the format very much. Both are very good, but I prefer PR</p>

<p>Cliffs is EXTREMELY necessary for bio, but refer to your textbook for diagrams (Cliffs aren’t colored, which make them harder to understand.)</p>
