CREDITS--Credits are awarded on the semester-hour basis. The distribution of time between class activities and outside preparation varies from course to course; for the average student, however, at least forty hours of work per semester planned and arranged by the University faculty are required to gain 1 credit.
GRADING SYSTEM
The grades of A, A-, B+, B, B-, C+, C, D, and F indicate a gradation in quality from Excellent to Failure and are assigned the following grade-point equivalents:
Grade, Grade-Point Equivalent
A, 4.00
A-, 3.67
B+, 3.33
B, 3.00
B-, 2.67
C+, 2.33
C, 2.00
D, 1.00
F, 0
Grade points are determined by multiplying the grade-point equivalent of the grade earned by the number of credits for the subject, for example, ENGL 015 GWS, 3 credits, with a grade of A (grade-point equivalent 4.00) yields 12 grade points.
