The answer key for the midterm exam is now available. Just as before, I’ve put the answer key in the password-protected “Readings” section of our website. (Remember that the password is listed on the syllabus.)

Here are the numbers that I provided in class today concerning the overall class performance, and a rough grading scale:

Mean score: 47.8 / 60
Median score: 48.75 / 60

A: 52-60 (86.6%-100%)
B: 43-52 (71.6%-86.6%)
C: 34-43 (56.6%-71.6%)
D: below 34 (below 56.6%)
F: N/A

As I said in class, I thought the overall performance was quite good. Just about everyone managed to attempt all parts of the exam, and for each problem, the majority of you saw what was going on. Since we won’t have time in upcoming classes for any more discussion of the midterm problems, be sure to have a look at the key.
