FINAL GRADE
UPDATE (06/30/06)
<>Final
grades are done. All letter grades are final. The average
on the Final Exam was 71% which was fairly consistent with the quizzes
over the course of the five week session. You can make an
appointment to stop by after August 16th to take a look at your exam
and discuss it.
I hope you all have a great rest of your summer!
