This is largely my fault, but the permanency of the error bugs me. My first time using University Life, I noticed the option to make a cheat sheet around exam day, and foolishly used it for both the sims I had at the same time. Where I go to University, some courses allow you to bring cheat sheets, courses like physics, chemistry, and statistics which have a lot of formulas to keep track of (some let you bring your own, others provide them for you), so I was thinking that I was going to be underprepared if I didn't make them.
Of course, as soon as their made I read the moodlet and realized my mistake, and then found out there was nothing I could do about it without loading a much earlier save. I didn't tell them to cheat, and they didn't need to, but they got caught on their first and second exams, making for 5 exams failed between them (it lowers your academic score so much that you can't pass subsequent exams without cheating).
So basically, since my sims would have passed everything without cheating and I was being silly, I picked an option that essentially allows me to volunteer to fail most or all of my exams, and I can't decide down the road to be honest. They still passed, but went from A's to C's.
