Final grades are posted
Well, it is done. Your final grades have just been posted. If you are interested in what your final exam score was, you can check Moodle, which now has everything up to date.
General comment on the final exam: only one person changed by a letter grade after the final exam, mostly you stayed about where you were. The problems were much, much better than the multiple choice, which I sort of expected. Overall, I was pleased.
The multiple choice section of the final was scaled by about 16% upwards to enforce an average of 75%. The problems section actually had an average of exactly 75%, so no scaling was necessary - good work! The final exam grade is then the average of the scaled multiple choice and the problems grade. Below is a histogram of the overall final exam grades:
It is perfectly symmetric, which is just ... creepy. So it is: 75% average, perfect bell curve.
A similar plot of overall final course grades is below. The average grade for the course was a 78%. Keep in mind that when assigning letter grades, I always round up (so 79.01% is a B-, 78.99% is a C+) - thus translating the plot below to the number of A's, B's, etc. is misleading.
Anyway: have a good vacation, and take a much-needed break. Feel free to email or call me with questions about your grades, or anything else.
