<p>Also on the AP, there's the whole fact that you have to actually produce your own answers (Shudder). On the SAT II it's all just finding the right answer, so if you have a general idea, you can often get the answers right.</p>
<p>But yes, I second GoldShadow in that there is a lot more depth on the AP... It's not that bad though, as long as you actually take the class (I'd imagine self-studying it would be a major pain in the ass though, lol)</p>
