Grade Scales for Exams
MAP 2302, Section 5607 (17280)
Elementary Differential Equations
Fall 2019

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).

A cutoff like "90.5" in a grade-scale does not mean that any half-points were given to any student on the corresponding exam; it simply means that I thought 91 was too high for the cutoff and 90 was too low.

Each exam's 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. The student population from which these averages and medians may include students who have since dropped the class, and thus may not reflect the averages and medians of just the students who are currently enrolled in the class.

The class GPA was 2.64. This average includes an E for a student who never took any of the exams, and may never even have attended class, but was still on the class roster at the end of the semester. Not counting this student, the class GPA was 2.75. The class GPA for the last MAP 2302 section I taught (Fall 2018) was 2.67.

I will not be holding any office hours until next semester. If you have a question about your grade, or would like to look at your graded exam, please DO NOT EMAIL ME THE QUESTION; please see me in my office after Jan. 6 (check my home webpage after Jan. 5 for my schedule). I will not send or discuss grades by email.
