<p>I know that CB specifically states that mechanical pencils are not allowed on the AP, yet I've used them last year while testing. I was just wondering how strictly they enforce that rule; I'm probably bringing some wooden pencils as backups just in case.</p>
<p>Also, are you required to write in pen only for the FRQs or is there an exception for science and math exams? For calculus, I feel really uncomfortable with writing my answers in pen. </p>
