Okay I am going to be taking four AP classes this upcoming school year. I would like to know what AP prep books would be the most useful for the classes I will be taking, and whether or not it will be necessary.
I was thinking of buying these prep books online.
APUSH - crash course Amazon.com: AP U.S. History Crash Course (REA: The Test Prep AP Teachers Recommend) (9780738608136): Larry Krieger: Books
AP LANG - I have no clue which one would be good or if I even need one.
AP Bio - Cliff notes/Princeton Review/Barrons Amazon.com: CliffsAP Biology (Cliffs Ap Biology) (9780470097649): Phillip E. Pack Ph.D.: Books
AP Pysch - Barrons Amazon.com: Barron's AP Psychology with CD-ROM (9780764195259): Robert McEntarffer, Allyson J. Weseley Ed.D.: Books
If you recommend any other brands, please tell me about it. I'm open to suggestions.
Also, I have provided a link to the ones I am leaning towards on buying. I'm not too sure if they are the latest ones though. So if I were to buy the ones I have provided a link for, would those be suitable? Thank you! :)
