I am currently #12 on the IS wait list, up from #17 on the original letter and up from #14 from the first email update. I was calling to ask if students on the alternate list can come to the getting to know you event this weekend, but we aren't invited 🙁
I wanted to know if being on the wait list prevents you from reapplying for the next cycle, but that isn't the case. You can still reapply while retaining your spot on the wait list. I was told it's still early to ask for an appointment to talk about how to improve your application, so I'll probably wait another month or so for that. The majority of the students accepted off the wait list get in late April-early July with most of the movement around May, and only one or two students are usually accepted in the July-August period. She also told me that usually they only have one student decline the wait list due to acceptances at other schools, but this year there were five.
