Final Grade Calculcation for Dr. Plank's Classes

James S. Plank

This web page applies to COSC 202, 302, 307, 360 and 367. It does not apply to COSC 494/594. Please see http://web.eecs.utk.edu/~jplank/plank/classes/cs494/494/index.html for how grades are calculated for that class.

Grading Scale

My grading scale is as follows:

A+: 95 - 100
A: 90 - 95
A-: 87 - 90
B+: 83 - 87
B: 80 - 83
B-: 77 - 80
C+: 73 - 77
C: 70 - 73
C-: 67 - 70
D+: 63 - 67
D: 60 - 63
D-: 57 - 60
F: 0-57

Labs

Your lab score is converted directly to this scale by dividing your total lab score by the total number of lab points, and multiplying by 100.

Exams

To convert exam scores, I do the following:

I set the following variables for each exam (listed on the exam cover page).
- top is the highest possible score.
- a is the lowest possible A.
- b is the lowest possible B.
- c is the lowest possible C.
- d is the lowest possible D.
- s is your score on the exam.
If s was between a and top, your converted score is 90 + 10 * (s-a) / (top-a).
If s was between b and a, your converted score is 80 + 10 * (s-b) / (a-b).
If s was between c and b, your converted score is 70 + 10 * (s-c) / (b-c).
If s was between d and c, your converted score is 60 + 10 * (s-d) / (c-d).
If s was between 0 and d, your converted score is 60 * s / d.

Your exams count 50 percent, and your labs count 50 percent.

Attendance

Attendance in class is mandatory. You may miss six classes, unexcused. After that, you will be deducted 2 points for each class you miss.

In COSC 202, 302 and 307, attendance in labs is mandatory. You can miss one class unexcused. After that, you will be deducted 2 points for each lab you miss. In COSC 360 and 367 lab attendance is optional.

In all classes, the maximum total deduction for lab and class attendance is 10 points.
