Notes on course grades

Course grades were determined by the following distribution:

A: 85% and higher

B: 75% - 84.9%

C: 60% - 74.9%

D: 50% - 59.9%

F: below 50%

Class average: 75.7%

Notes:

Five points were "free". The syllabus called for 20 percentage points allocated to homework assignments. Homework scores summed to 15 total points. So 5 more were added to everyone's homework point tally.

The C range is rather generous.

The average scores and the grade distribution were determined before extra credit was factored in; this was done to keep from artificially inflating the mean score. Your grade was initially determined before the extra credit. Then the extra credit was added to your score. Then your grade was bumped up if you moved into the higher grade bracket. For 14 people in the class, the extra credit improved their grade.

My Bad (but why didn't someone call me out?)

Unfortunately an editing error resulted in some bad information on the review sheet for the final exam. The blog address listed for "info" and "answer key" was for my Wednesday night class. So if you went to that page you probably didn't find the answers (as their answer key was not posted until Monday the 7th).

I figure most of you had the blog page bookmarked anyway and wound up with the correct info.

Anyway, please accept my apologies, but if anyone was thrown off (a) you could have asked and (b) you should have been able to figure it out!

Good luck with the rest of your finals.

Have a safe and sane summer.

Answer Key to Study Questions for the Final

Here is the answer key. Let me know if you think there are any errors.
