Math 232 Overall Mid-Term Exam Marks
The overall mid-term exam mark is based on the best two out of three
mid-term exams. However, adjustments had to be made in order to create
a level playing field between the three exams, due to their differing
distributions of marks. In order to do this, the letter grade-cutoffs
for mid-term exam #1 were taken to be the standard, and the marks for
mid-term exams #2 and #3 were adjusted upwards, so that the assigned
letter grade cutoffs would agree for all three exams.
Details of how the mid-term exam marks were adjusted can be found in the Adjusting Math 232 Mid-Term Exam Marks Maple Worksheet,
in case you want to check the calculations.
After adjusting the mid-term exam marks, the average of the best two out of
three exam marks for each student was taken, and normalized to be out of 30
points. The results are summarized in the following histogram:
