In the College of Science, not more than two courses or 6 semester hours of credit, whichever is greater, may be repeated to satisfy the requirements for the degree. Only such repeats will be counted in calculating the cumulative grade-point average.

No grade changes are permitted after the end of the final examination period one calendar year from the semester in which the student registered for the course. In calculating the overall cumulative average, all graduate-level coursework completed at the time of clearance for graduation will be counted unless the student is immediately continuing on for a PhD degree in his or her department.

Students cannot elect a pass/fail grading scheme for College of Science courses, unless the course grading scheme is designated pass/fail.
