Course grades. The mean score was 529 out of 600 points and the median was 530.5 (both are roughly 88%, equivalent to an A- course grade). Distribution of course grades was slightly higher than for the mid-term grades: the median class grade is A-. Individual grades were six A, two A-, four B+, one B and one C. Congratulations for making this a very fine class!

Individual course grades will be sent to the Registrar's grade-receiving server Monday afternoon, May 12, and should be available from PeopleSoft by Monday evening or Tuesday, May 13.
