I was wondering if this one thing I did would disqualify me from passing a security clearance. When I was in school, I once completed a writing assignment that was due on Monday, on a sunday, then I sent it to my professor. Then one of my friends approached me and I talked about the assignment with him, and he told me I did one little minor thing wrong. So I opened up the file again, fixed the minor problem, and sent it to my professor again saying, "Oh I sent you the wrong copy the first time. This is the final draft. Sorry." I think the professor knew I was full of shit, but he accepted it anyway. It was really a one time lapse in judgment that I've had and I don't want to go through the rigors of the whole application process with this potentially disqualifying me or coming back to bite me in the ass.
