Anyone ever messed up like this?

<p>for the grid-in math section, there's only 8 MC as you all know</p>

<p>so the proctor was collecting the test, so i flipped open my booklet to see if i messed up anywhere, and sure enough i did (i even mess up bubbling on my practice tests at home)</p>

<p>i had NINE questions bubbled in instead of eight, so i quickly look back and saw that the last 3 answers (6-8) were BCE i think, so i chcked my booklet and i had 6B 7C 8E 9D</p>

<p>now i'm scared because i don't know how that #9 got there (i erased it, but even if i didn't it wouldn't have mattered)</p>
