Congratulations on your acceptances!
I think that that may be the case with the waitlist but we don’t know for sure. I interviewed on feb 26th. Also, last year I was notified of my place on the waitlist on Monday March 27, which would correspond to this upcoming Monday.
All that said I know some ppl last year had heard about waitlist like ten days before I heard so take that for whatever it’s worth
I called admissions this week. They said some decisions have gone out but not all of them and we will know by the end of the week. ¯\_(ツ)_/¯ I am in the same boat as you.
