UC Davis Waitlist question

I got waitlisted by Uc Davis and if Im accepted over the summer do I have to accept the offer?

You’ll be notified mid May. Waitlist is non-binding.

If you are moved off the wait list and get an off they usually give 3 days to respond to it. So accept it, deny it or ignore it (same as denying). The email would tell you how long you have to respond.
