<p>So I erased two questions; unfortunately, there were very slight smudges on both that I couldn't get off. Will it be caught by the scoring machines? How good are the machines at "deciding" between erased and non-erased answers?</p>
<p>Don’t worry about that. There’s always going to be a smudge left, but I’m fairly certain the machine can pick it up, as long as you darkened the other one in completely.</p>
<p>yes I did darken the other circle completely, according to consolidated list, the worst that I can get in CR(section where I erased) is 700. So anything below that, I’m asking for handscore.</p>
