Best Guides for AP Classes

What are the best guides for the following AP classes (I plan on buying them soon and studying over the summer to prepare for the classes):
AP Calculus
AP Chemistry
AP Literature and Composition

I have heard Barron’s and The Princeton Review are good for all of these but any suggestions are good. If at all possible, if anyone had to choose between Barron’s and The Princeton Review for each one of these, which one would they choose. Thanks.

I would choose Barron’s, especially for AP Calc AB, which I did last year. The practice tests help a bunch and turn out to be quite similar to the ones on the actual test.

@BoyAtWilliams I don’t know which AP Calculus class I’m taking (AB or BC), so I decided to get Barron’s which conveniently contains both Calculus AB and BC studying materials and practice tests for each.
