# MAT67 Modern Linear Algebra - Fall 2011

## News and announcements

• (12/11/11) Have a great winter break!

• (12/11/11) Final grades have been uploaded to the system and should be visible soon on SmartSite/SIS. Here is an explanation of how the grades were computed: a total score (in the range 0-100) was computed as a weighted average of the midterms, final, and homework assignments, as described in the syllabus (this total score can be seen on the course SmartSite grades, under "Final numerical score"). The letter grades were then computed from the total score according to the following cutoff ranges:  A+ top 2 students A 80-100 A- 70-79.999 B+ 67-69.999 B 63-66.999 B- 60-62.999 C+ 58-59.999 C 55-57.999 C- 50-54.999 D 48-49.999 D- 45-47.999 F 0-44.999

The mean total score (among students who took the final exam) was 62.8, and the highest total score was 92.13. The following table shows the distribution of the letter grades, computed from among students who took the final exam:
 A range (A+, A, A-) 30 students (42.2%) B range (B+, B, B-) 17 students (23.9%) C range (C+, C, C-) 11 students (15.4%) D range (D+, D, D-) 5 students (7%) F 13 students (18.3%)

• (12/6/11) Click here for solutions to the practice exam (note: it is highly recommended to try solving the exam yourself before looking at the solutions.)
• (12/4/11) Yvonne Kemper will hold a review session on Wednesday, December 7 at 6-8pm in Young 184. You are encouraged to attend and prepare any questions you would like answered.
• (12/2/11) Click here for a practice exam with some notes to help you study for the final exam. Solutions will be posted next week.
• (10/28/11) The grades for the midterm exam have been posted on SmartSite. The average grade was 51, the median grade was 52, and the standard deviation of the grades was 19. Here is a chart showing the distribution of the grades:

• (10/21/11) Yvonne Kemper will hold a review session for the midterm exam today at 4-5:30 in 119 Wellman Hall.
• (10/11/11) The Student Disability Center asks that students interested in serving as paid notetakers for this course please contact Russ Zochowski. Notetakers are paid a stipend of \$25 per unit. Students are asked to put notetaker, the course title and number, and instructorâ€™s name in the subject lines of their emails.
• (9/30/11) On the "Quick Links" section above there is a new link to a pdf file with summaries of the content of my lectures so far (including a small amount of material not yet covered). I will periodically update this file with more material.
• (9/26/11) The textbook has been updated by the authors with changes to Appendix A. If you have previously saved the file, please redownload it.
