<p>Are CB's machines good at picking out the answer you pick after you erase a lot? I picked all the correct SC answers for the June SAT but that was after I erased a ton due to uncertainty in my answers. I did my best to erase but I don't want to get screwed over.</p>
<p>If the mark you made was dark enough, I think they’ll still be able to pick it up. :)</p>
