Grade Scales for Exams
MAP 2302, Section 3875
Elementary Differential Equations
Spring 2017

The exam-grade 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; 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).

Each average and median below was computed from the scores of only those students who took that exam, and did not have a cheating-penalty imposed. For example, zeroes for students who missed an exam without an acceptable excuse are not averaged-in.

If you have a question about your grade or would like to look at your graded exam, DO NOT EMAIL ME THE QUESTION; you may write to me after May 15 to arrange to see me in my office. I will not send or discuss grades by email, and will delete, without responding, any email requesting a response related to grades or exam-scores.
