• There seems to be confusion on how the final letter grade is determined. We calculate a straight percentage for each student. This is 35% times (final exam score)/150, plus 15% times first midterm percent, etc. Then the professor uses some cutoffs to determine letter grades. I'm not sure how he decides cutoffs. I suspect they're related to his cutoffs for the three exams. There is no predetermined letter grade distribution for the class. The "curve" is the fact we don't use 90%=A-, 80%=B-, etc, but it really is a misnomer.
• Practice exam on Friday Dec 10 6:30-8:30 in Wheeler 213, for my sections and Adam Booth's sections. Here are the electronic verions of the practice exam (pdf, postscript) and the solutions (pdf, postscript). Adam and I still have some hard copies.
• Remaining office hours for the semester (all in 1045 Evans): Friday Dec 10, 10-11; Monday Dec 13 most of the day (end at about 6 actually, because Evans closes -- can still send me email); appointment. Please come by and pick up any remaining homeworks and quizzes.
• All grades except the final exam have been entered into the online gradebook. Please check if there are any errors. As far as I can tell from the gradebook, A = 92+, A- = 85+, B+ = 80+. These might not be the cutoffs for the final letter grades.
• (As of Sunday Dec 12, 4:31 pm) Not all the scores on the online gradebook have been "released" yet. So you will not see your scores for HW 11-15 and quizzes 9-12, but I did enter them, and they will appear eventually. Currently the gradebook is calculating a percentage based on your best 8 homeworks and best 6 quizzes, but this is temporary.
• (As of Monday Dec 13) All scores (except for the final, obviously) have been released.
• Quizzes given in section: 1B, 2B, 3A, 4A, 5A, 6A, 7A, 8B, 9A, 10A, 11B, 12B. Feel free to try the other version for practice.
