Grades
I have updated grades on MasteringPhysics, which includes exam 3 scores and your overall grades. Have a look.
Exam 3 wasn't too bad, but I did scale it a bit. After scaling up by about 6 points for everyone, the average was 78.5 with a standard deviation of 10.5. Not quite as high as the first exam, but on par with the last one.
Most of you stayed about where you were at going in to exam 3, and the grades didn't change much overall. I'm not saying everyone is going to be happy, but most of you should feel pretty good about how you did - the overall class average was a solid B, nearly a B+.
Anyway: I'm not going to post final grades on myBama just yet, not until I've reviewed everything a few more times. If your grade ended up within ~0.5 points of a grade boundary (say, 89.5), I will carefully review your grades and re-grade your final exam to make absolutely sure of your grade.
Calculating final grades is agonizing, and I hate having to break a whole semester's performance down to a single descriptor. Not my idea though, has to be done ...
