AP Calc AB Book Difficulty vs. Real Thing

<p>So I am studying for the AP Calc AB test with Barron's and Princeton Review so far. I'm just wondering how difficult the real test is compared to these practice tests (or any other tests in other review books). Any help would be greatly appreciated!</p>

<p>PR is easier than the real thing, and Barron's is a bit harder.</p>

<p>Yea Barron's is definitely harder, but I don't know about PR</p>
