This exam was too long. I'm sorry about that. I never intend to write exams that take that long, and I don't like putting you through that stress, which is why I've graded this so quickly. I have scaled the grades so that you could get an A even skipping two of the five problems.

The ranges of grades are below. I am not breaking up grades into "B+" or "A-". Instead, I simply break them up into ABCD, and use those scores to calculate your final scores. When I get the final scores, I will break up the B's into A-/B+/B, and the C's into B-/C+/C.

Also, since this exam was so hard, I will be flexible about its weight on the final grade. For example, if you nail the final AND your lab grades are good, I will minimize the impact of this exam on your final score.

A+: 40 to 60
A: 34 to 40
B: 28 to 34
C: 22 to 28
D: 17 to 22
F: Below 17
