Please keep in mind that having a position on waitlist does not guarantee you will have a seat in a class. A seat will only be available if someone drops their seat before the end of add/drop Sunday, January 28.
We would recommend you check the position you have on the waitlist; this post shows you how https://www.instagram.com/p/CzmVdqlAudy/
If you are in position one, you have a better chance than if you are in position five. You can also speak with your advisor about alternative classes you can take.
Ensure you have no holds that prevent registration on your account, if you do, you won't be able to register if you get the notification a seat is open.
