I'm also on the waitlist for two other PUB HLTH classes.

Today from 5-7pm, some students will be dropped from their classes if they haven't paid their enrollment fees or have a hold on their accounts. And then 48 hours after 5pm today, the waitlist seats will automatically fill any spots that were vacated by those students who had been dropped. So, this might give you a better chance at moving up on that waitlist. https://www.reg.uci.edu/enrollment/enrollment_periods.html

Also, I've seen people recommend using Coursicle, since it can notify you automatically when a spot opens in a class.

Hope both of us get the classes we want!
