Every class is offered for a grade option, either letter grade (A through F) or satisfactory-unsatisfactory (S-U).
See: S-U Grades
Some classes are offered for either letter grade or S-U grade, giving students the opportunity to choose the option they wish to be graded under. Students must make the decision on the grade option for all of their classes before the end of the third week of the semester (the add period). Check with the Office of Student Services, 180 Statler Hall, for the specific date each semester.
