full term courses, which extend over the entire length of a term
short courses, which are only offered for some part of a term
You can add courses which are not full term through the first two days of the course (unless the course is five or less days in length, in which case it may only be added through the first day).
You can see the drop/withdrawal/refund dates by looking at the course details when searching for a course. The dates can also be seen by placing your mouse over the icon on your schedule. This will display "hover help" and the official date to drop and withdraw. You can also see these important dates on your printed class schedule.
You can change the grading method of short courses through the first five days of the course, if it is more than five days long, or through half the course's length, if it is five or less days long.
Specific dates for summer terms, which contain many courses of varying lengths, can be found under the Important Dates for that summer term.
