Course grades:Final course grades have been posted outside my door. The cutoff for an A is 86%, the cutoff for a B is 77%, the cutoff for a C is 60%, and the cutoff for a D is 48%, resulting in 12 As, 9 Bs, 9 Cs, 3 Ds and one F among the 34 people who took the final.

First Midterm:The first midterm was on Friday, Feb. 9, from 9-10 AM, in rooms RLM 6.116 and RLM 6.122. (Just come to 6.116 and I'll send half of you across the hall to 6.122). The exam was closed book, and calculators were NOT allowed. However, you may bring a "crib sheet" with handwritten notes on both sides of the paper.

The class generally did well, with over half the class getting 90 or above. The average was around 83.

## The second midterm was on Friday, March 9, from 9-10 AM, in rooms RLM 6.116 and RLM 6.122. (Just come to 6.116 and I'll send half of you across the hall to 6.122). The exam was closed book, and calculators were allowed. As on the first exam, you were allowed to bring a "crib sheet" with handwritten notes on both sides of the paper. This exam covered through Section 3.7. (NOT 4.2, as previously indicated.)

Second Midterm:The grade distribution had two lumps, one centered around 90 and the other centered around 65, with nobody scoring between 70 and 78. The average was 74, and the median was 80.

## The second midterm will be on Monday, April 9, from 9-10 AM, in rooms RLM 6.116 and RLM 6.122. (Just come to 6.116 and I'll send half of you across the hall to 6.122). The ground rules were the same as the 2nd exam. The average was a 60.2 (ouch!) and the median was 65.

Third Midterm:## Final Exam:

The final exam was on Saturday, May 12, 2-5 in RLM 7.104. The ground rules were the same as the 2nd and 3rd midterms, except that two crib sheets were allowed. The exam itself is posted below, together with their solutions. In my opinion, this was a fairly easy test, and, except for problem 5c, all questions were straightforward. Even problem 5c was similar to problem 7c from the 1996 exam.The class average was 74.1 and the median was 72.5. This was the only test where the average was higher than the median, indicating a longer tail on the high end than the low end.
