The scale for each assignment or exam below is created after the assignment or exam is graded. These are the cutoffs that will inserted into the announced grading formulas to determine the "raw score" cutoffs for final grades.The cutoffs given below are the bottom for the "flat" grade, not the minus grade. (For example, if the cutoff listed for a B is 50 points, then 50 is a B and 49 is a B-). The A- cutoff is 1/3 of the way down from the A cutoff to the B cutoff, the B+ cutoff is 1/3 of the way up from the B cutoff to the A cutoff, the B- cutoff is 1/3 of the way down from the B cutoff to the C cutoff, etc. (except that I do not give D-'s; anything lower than the D cutoff is an E).
A cutoff like "17.5" in a grade-scale does not mean that any half-points were given to any student on the corresponding assignment or exam; it simply means that I thought 18 was too high for the cutoff and 17 was too low.
Each average and median below, except for homework totals, was computed from the scores of only those students who turned in that assignment without a lateness penalty, or took that exam. The average for total homework points was computed just from currently-registered students, and therefore does not reflect for students who may have turned in earlier homeworks (and are therefore reflected in the averages for those homeworks) but have since dropped the class.
Homework
Scores (and cutoffs) for the different assignments are simply added together at the end of the semester. Example: if there are only two homework assignments, worth 60 points and 80 points respectively, and the "A" cutoffs are 50 and 70 respectively, then the "A" cutoff for the homework component of the final grade is 120 out of a possible 140. A student earning 55 points on each of the two homeworks would have the same homework grade as a student earning 30 points on the first assignment and 80 points on the second.
