<p>Is this one hard? I might try to self study it, but I'm just wondering how long I'd have to study it. And any good books to use? Princeton Review or 5 steps to a 5 or others? I'm just curious.</p>
<p>Comparatively speaking, stats is a really easy AP. Basically any review book will do.</p>
<p>^ I agree.</p>
<p>Personally, I find 5 Steps to a 5 better, though. :)</p>
