You're very welcome

Happy to help.
I don't know if they'll share this kind of info, but I'm sure they are still admitting people off the WL at the moment.
I know that when they first called to notify accepted students they would ask people on the phone if they would attend the program this year because they were compiling the waitlist. But back then (early or mid-March) everyone thought the fall semester would be in-person. Situation changed, therefore many students, myself included, decided to defer even though we initially answered yes to the question. So they are admitting many people off the WL in order to maintain the class size.
