<p>I buy the cheap Bic mechanical pencils, and they’re all #2’s. I’ve also used them on every standardized test I’ve taken in high school with no adverse effects. They just work better for me.</p>
<p>For the problem-based APs (math, sciences, computers) it’s a good idea to use a pencil, but I think they will allow use of a pen. For the essay-based APs (English, history), they usually require a pen.</p>
