Grades

I hate that I need an 87% on my physics final to keep my A, but if I wanted to get a B I'd only need to get a 37%. It doesn't even matter if I do the extra hw and quiz. I'm getting another B in this stupid class.

If I get a 0 on the final I get a 72%, a 50% my final grade is an 82%, a 75% brings me to an 87% an 82 gets me an 89%. I hate this.
