<p>On the SAT I accidently used one of my bad erasers to erase one of my answers and it smudged pretty badly. I spent a long time erasing it (with my good eraser) and bubbled the right answer darkly...
My question is, does the machine still pick up this smudge, because its still there somewhat, or does it just see the pencil mark? Its been bothering me.</p>
<p>That's been bothering me, too. I really hope the machine can differentiate between smudges and marks.</p>
<p>If you feel it affected your score at all, you can pay $50 for CB to hand-grade your test.</p>
