**Final Exam Results.** Once again, the class performed very well. Out of a maximum of 200 points, the mean score was 172 (86%, equivalent to a B+). Median score was 171 (also B+). Scores ranged from 122 to 202, with the following distribution: A: 5 (182 to 202 points); A-: 2 (175, 177 points); B+: 1 (167), B: 4 (162 to 165 points); C+: 1 (155 points); D: 1 (122 points).

**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.

** Maple Worksheets.** Maple worksheets for the course are available here in HTML format. If Maple is installed on your computer, you can download a file, edit it and run it without the need to come to MSB 203. Latest update (April 14) includes Maple routines for matrices and determinant calculations.
