If I'm enrolled in a class already that has a lecture component as well as a discussion component, can I keep the same lecture but choose a different discussion? The case is, I'm enrolled in the class but now the class is waitlisted for both discussions and lectures. For some reason, there are people on the waitlist but it says that there are still seats available in the class. On myUMBC with scheduling my classes, it shows me that the class is open even though there are people on the waitlist.
