**For my Fall 2009 class, click here.**

**For limited-distribution materials such as
homework solutions, I am also using the Sakai
website for this class.
**

**The final exam is graded, and grades are now on Sakai**- For this section, the average score was 77.3 and the median score was 77.8. These scores were roughly similar to the overall profile for all sections, and also quite similar to the second midterm.
- The grade distribution had a single peak, and not two distinct peaks as it did on the midterms.
- In my view, the exam was long and comprehensive, but most of it should not have been very difficult. Your scores on the first and third algebra questions (advertising and investment) were lower than I expected. Otherwise, you performed well.
- Both final exam scores (out of 100) and course grades may be found on Sakai.
- Enjoy your summer!

- There will be no more office hours for the semester. To see me,
e-mail for an appointment.

My office is in the J. H. Levin building, room 255. My usual office hour schedule is as follows:

- Mondays 2:30-4:00PM
- Wednesdays 2:30-4:30PM
- Or other times by appointment.

I will depart from this schedule in special circumstances, as noted in the
announcements section above.
