Just a data point—in 24 hours, 4/5 more people joined the Facebook group, and nothing has been reported here. Even if these were previously accepted students who joined the FB group later, I find it hard to believe that RSOM overaccepted by a margin of now more than 30 applicants (and counting). I also find it equally unlikely that there will be 0 waitlist movement, because even the most competitive schools have applicant attrition, and RSOM is no exception.
Yes, the class is probably "full" right now, but that doesn't necessarily mean it will remain so in the next few weeks (CTE). Had 135 applicants committed to RSOM by now, then there would be no need for the adcom to deal with the WL anymore, and we would be cut loose. While emotionally I have moved on, logically there is a non-zero chance of getting in. Slim? You bet. But you can't write it off as a done deal yet, objectively.
