Practice Final Exam:
Here is a practice final exam, and here are solutions.
Final Exam:
Here is the final exam and here are solutions. This test was not short or easy. The mean was 74.5, the median was 75, and the standard deviation was 12.9. I predict that grades between 79 and 100 would be on pace for an A during the term, that grades between 60 and 78 would be on pace for a B, and that grades 59 or below would be on pace for a C.
