If the course you've been taking seems to have disappeared from your "My Courses" Quick Links, click the "Find Courses" tab at the top and use the drop down menu to access either "Past Courses" or "Future Courses". All GullNet courses are tied to a particular term (e.g. FA13 UNDG) and go by the official dates that the term runs. If a course is listed under a term but the course actually runs past the end of the term and crosses over into the next term, these courses stop being "Current Courses" and become "Past Courses" and disappear from "My Courses" 15 days after the previous term's end date.
Likewise, a course tied to the next semester, will be a "Future Course" until 15 days prior to the start of the new semester.
