During the first 5 days of a semester, you can drop or add any course to your current semester's class schedule.
Locate the listing of courses in the Current tab of My Courses in the Student Community.
Review the courses that you are currently enrolled in and decide which course you want to edit.
Icons will appear in the bottom-left corner of the portlet to help you quickly drop/add/swap your courses. Use the drop icon to drop courses from your schedule without penalty during drop/add. Use the add icon to add classes to your schedule. Use the swap icon to swap one course for another.
