The final has been graded. I may not be able to post a key before Christmas. Scores ranged from 43-119 (out of 130). The mean was 80, the median was 81. We curved to a B average, such that 27 out of the 45 people got a B or better for the exam. Final grades were given such that the class mean was 3.38. The median was an AB (of 45 people, we gave 11 As and 16 ABs, which is a lot for an undergrad class). Specific details will be sent to individuals, although I might not get to do it before Christmas. Happy holidays.
