During the add/drop or “change of schedule” period, you can drop classes through myBama.
After the add/drop deadline but before the 10th* week of classes, you can still use myBama to drop a course. The difference is that when you drop a course after add/drop, your transcript will show a “W” for that course.
*For fall and spring semesters, add/drop ends one week after the first day of classes and the last day to withdraw with a grade of “W” falls around the 10th week of classes. During Interim, Winter Interim, and summer sessions, however, both intervals are considerably shorter. Consult the UA academic calendar at registrar.ua.edu for dates.
