AP Biology Prep Book?

[ENOMUSHIKI]

Okay, I'm in a situation where I need to study AP Bio all by myself. No teachers because I live outside the states. Just a Campbell and Reece textbook and a Princeton Review prep book. SO far, I've looked over everything once, including looking up the important details in the textbooks et cetera et cetera. My sister did this last year and she scored a 5. But the thing is, I just flipped through the AP BIO Barron's prep book, and it had all this information that wasn't in Princeton Review or even in the textbook. So I was wondering if it's Barron's that has too much info, or if it's Princeton Review with too little?

I'm in AP Bio right now, and we've just been using the Campbell textbook, it covers almost everything you need to know!

As for prep books, my teacher recommended Cliffnotes, which I notice you didn't mention. However, these prep books alone are not enough to study for the AP exam, make sure you read the textbook(s) too!
