## Grades for 2nd midterm

Marks get adjusted and then converted to letter grades only at the end of
the course. But people need feedback about how they're doing, and that
is the purpose of this page.
The exam was out of 80. It was well done, but for purposes of
predicting final grades,
the scores are probably a bit on the high side. So I'm going to give
conservative predictions at this point.

- 75-80: A+
- 66-74: A
- 62-65: B+
- 58-61: B
- 53-57: C+
- 49-52: C
- 44-48: D+
- 40-43: D
- 32-39: E
- 00-31: F

The mean score was 66.

The median score was 70.

The following is a "stem and leaf" plot of
the raw scores.
