I applied to R-C and am on the waitlist...what are the waitlist rumors?
If you read posts from last year there are some very unhappy applicants. Although the people in the admissions office are friendly it seems as though they dish out a lot of false hope and false information.
This year, there are people on LSN that have been accepted to RutCam without having applied! Meanwhile, the people in the admissions office will tell waitlist candidates that all the seat deposits are in and you will only get a seat if someone either withdraws or doesn't show. You can draw your own conclusions why RutCam does this.
The point of this is: the rumors are that in the past they waitlist you as a courtesy but then never admit anyone off of the waitlist.
