Answer sheets hard to erase?

<p>Does anybody else feel that it's hard to erase bubbles on those SAT answer sheets? That got me wondering, how sensitive are the machines when they score bubbling?</p>

<p>no, its pretty easy to erase answers!! invest in a good rubber and it should be fine!</p>

<p>if you have smudges, the machines will probably pick it up. That's what handscoring is for.</p>

<p>it's a bad pencil/eraser, not the paper used.</p>

<p>It's not so much smudges as traces of gray left over.</p>

<p>Hmm, I'm starting to worry a little now. On one of my math sections, I accidentally skipped a question at first, so I had to erase later on to push all the answers up. There really weren't any smudges or grey spots, but you could notice I erased..</p>

<p>Yeah, I've always been worried about that. I have good erasers but they just don't do the job. I always worry about the sensitivity of the machines.</p>

<p>Knavish, ur better than me, I did the same thing like u and also on the verbal parts for some stupid reason i put the answers in the math section and gotta erase it. I lost like 3minutes doing that. Maybe because I continued to study the night before. ~_~</p>

<p>The machines work pretty well. If more than one answer is picked up, or marks are detected in the wrong places (outside of the bubbles, on questions that don't exist) the answer sheet is referred to a human being to resolve the problem.</p>
