The credit weight is the relative value assigned to the course. A 1.0-credit course carries twice the weight of a 0.5-credit course and normally consists of three contact hours per week over an eight-month period (September – April). A credit denotes a 1.0-credit (or full-credit) course with 1.0 indicated in the course description. A 0.5-credit course carries twice the weight of a 0.25-credit course and is normally conducted over a four-month period. A half-credit course is indicated with the 0.5 weight in the course description, and a quarter-credit course as 0.25 in the description and is normally taught over a six-week period. However, courses may be taught over varying periods of time than these listed. In the program descriptions, the following symbols are used following the course number:
|One and a half credits (1.5)||‡|
|One credit (1.0)||*|
(0.5 credits do not have a symbol appended.)
Half (0.5-credit) courses are indicated simply by the course number consisting of the discipline code and a three-digit number. This system of notation represents a change from that used in all calendars prior to the 1993-1994 version, in which the symbol * was used to identify 0.5-credit courses.
For example, a student who earned an A in a 1.0 credit course would be given an 11, a C- in a 0.5 credit course would be given a 2 (4 points/2) and a B+ in a 0.25 credit course would be given a 2.25 (9 points/4). To calculate the GPA, all grade points are added together and divided by the total weight of the credits. In this case the GPA would be 8.71 (15.25 grade points divided by 1.75 credits).
Where letter grades are derived from percentages, conversion follows this chart unless the instructor announces otherwise, in writing, at the start of a course.
