does waitlist movement generally happen rapidly that week after sun may 15? For some reason I thought it takes time to process deposits etc, re-open files, and we would only hear back the next week (week of may 22)
I think it goes pretty quickly. Over the years I've seen my friends and several others through this process. as a result i've seen the trends in waitlist movement when they were in this dilemma.
So I've seen that at many places (i.e. USF and other Florida schools) there was movement in like literally 1-2 days post May 15th and often times even a bit of movement prior to May 15th. This happens more easily when there are ranked waitlists where they are not reevaluating everyone again.
I tend to think an unranked waitlist would take longer to process and make further decisions on then a ranked one.
Schools like USF, UCF, and now UF use a ranked waitlist. This makes deciding who gets off waitlist already set in stone. Therefore, it becomes a matter of making calls to the next person on the list when one person withdraws. This is rather efficient and makes movement quicker at such schools.
I know years ago friends got off waitlists like literally within 1-2 days post May 15th at USF med. I also knew several who got off within a few weeks before may 15th in this part of april we are in now i.e. 2nd half of april.
Even at UCF, there were at least 5 who got off waitlist prior to 2nd look just this past year. So there's definitely movement before may but most of it happens after that deadline as a lot of people wait til last min. for making their decision.
But at schools which are still reviewing waitlisted candidates, due to being unranked, there will be slower movement.
Good luck. Hope this clears it up.
