Petersons American Lit.

[Scholar Interrupted]

Peterson's is, oh, I would say about 25% harder than the real thing -- which makes it ideal for preparation. The Official CLEP Guide is best for giving you an idea what the questions are like, what type of material is covered, and what difficulty level you can expect. But you need more practice that the official guide alone includes.

I learned so much studying for AmLit. It's one of those CLEPs I'm really glad I did, and for more than just the credit.

Good luck!
