I don't remember my best grade. Lots of 100%'s and some that were worth more with bonus points, so 100something.

Worst, well I just flat out didn't do some assignments, so I guess a zero? Or if that doesn't count, I got several D's in math in high school. Oh how I hate math.

I obviously know nothing about the grading system in other places. What the heck is an E? <_<
