<p>On many of my AP tests, I had to erase an answer I marked and fill in a new bubble. However, I was not able to erase the marks completely. Will the CB scanners automatically mark those wrong?</p>
<p>Sorry man, but the answers you changed will be marked wrong automatically by the scanners</p>
<p>if you got them wrong.</p>
<p>And if I got them right?</p>
<p>They will be marked right…</p>
<p>Is it me or are the people on CC getting stupider and stupider?</p>
<p>Okay, so CB does have a good scanner…</p>
<p>I was afraid that it would think I tried to mark 2 bubbles</p>
<p>Nah, it’s fine if the bubble you erased appears slightly darker than the bubbles that were never filled in in the first place. As long as you have erased it as much as you could, you will be fine.</p>
<p>Okay that’s good, since I had to do that for 5 questions on Physics and Human Geo</p>
