<p>What happens when a pencil is used instead of a pen for a section in Biology?</p>
<p>Nothing. The graders just grade it.</p>
<p>So why is it a big deal?</p>
<p>They prefer you to use pen because the free responses are scanned first, then graded. So it’s to your advantage if you use pen… or write with pencil really darkly.</p>
