Lab courses normally have 2 CRN’s – one for the lecture component of the course and one for the lab. Make sure that you enter both CRN numbers or you will not be able to register in the course. Of course, the CRN’s must not have time conflicts with any of your other classes.

If you must wait list for a lab course, you can only choose that option for the lecture part of the course. Students are not permitted to wait list for labs.
