You may not register for two courses that meet at the same time or for courses with overlapping meeting times. If you want the second course instead of the one currently on your schedule, use the Registration option under the Personal Services section of MyUW and submit both the drop and add in a single transaction.
If you want to add a course that conflicts with another, you must add the second course, in person, at the Registration Office, 225 Schmitz Hall. Students must obtain verbal approval of both instructors to add a course that conflicts one hour a week or less. Instructor signatures on a Registration Transactions form are required for courses that conflict more than one hour a week.
