Finally got around to do this. It's a distribution of all grades I handed out in the Fall of 2010, treating pluses and minuses as one category of the same grade. I'm 99% sure I removed all the students who dropped. N=64
Grades followed a rough normal distribution, but the low number of Bs is notable. I'm not yet sure what to make of this: could be random, could be that my assessment material is decisive, could be the ability of Bethany students is bimodal and that's reflected here. But the graph is interesting nontheless.
