<p>I have never studied for any APs that were classes. Of those that were self-studies, I usually read through the textbook and prep book once, but never did much traditional “studying”.</p>
<p>There’s no causal link between not studying and doing well on AP tests. Rather smarter people tend to do well on AP tests AND tend to study less then everyone else - intelligence is the factor causing the performance and contributing to the lack of studying.</p>
