The questions and answers are in:

http://www.ccs.neu.edu/research/demeter/course/exams/m-3360-f00/

The midterm results are:

1 A+
5 A
2 A-
1 B+
1 B
1 B-
2 C+
1 C
2 C-

The point-to-grade map is:

Over 200 is an A
180-200: A-
160-180: B+
140-160: B
etc.
80-90:   C
60-80:   C-

For those who had a bad day, I will count the final twice
if the final is much better than the midterm.
