Dropping a Course
The drop/add period closes at the end of the second week of classes each semester. You may drop a course through ACES anytime prior to the end of drop/add. You do not need an instructor's permission, but you do need to be sure you remain in at least 4.0 credits, the minimum course load. If you drop a course, it does not appear on your Duke transcript.
After the drop/add period closes, you can no longer drop a course, but you may be able to "withdraw" from a course. You should always review your schedule as soon as the drop/add period is over during every semester to be sure you're enrolled in the correct courses. If you discover an error in your registration, you can correct it during the third week of the semester (Schedule Correction Period) through your academic dean's office.
