I believed that I was being unfairly marked with a biased grading.

I got access to admin privileges, found another students essay from the same class but different timeslot, knowing what grade they got after handing it in early, I changed nothing but the font and name and handed it in to get a full letter grade less than the original student had.

I couldn’t keep myself from complaining about it and was suspended over it, but it was a privilege when I knew I was right.

Edit: To clarify, it was the same teacher for both class groups.
