I was very shocked by the class averages and curve for my quantum mechanics course. The exam was curved to (brace yourselves) 55/100 as an A. Yeah. Kind of shocking, frankly. Of course, the class average was 47.5 or something on that order. My own score was an 80, which I'm not terribly happy with, but apparently that's an A++++ now. This is at Arizona State University. How would this compare with curves other people have experienced? I would assume the curve at Stanford or MIT would be much less generous... That's just the first part though. I'm curious, how much comprehension of the material would you say you had as a student? There are all sorts of results in my quantum course I probably couldn't derive if you asked me in the street, although there are certainly a few which I could (e.g., what are the eigenfunctions of an infinite square well, derivative relations for delta function potentials etc). How many of the details would you say you had mastered as students? With curves this low, can't students slide past without really understanding anything and still get good grades?
