pdr0724 I attended a Q&A webinar today and ad com people suggested that they are reviewing R3 candidates and it is reasonable to assume that those who applied after April 8th will hear back after May 13th (decision release date for R3). So, I would assume that both appealers and extended R3 applicants should be patient and wait a couple of weeks.
After making an admit decision on May 13th, the school will know how many more people they might need based on the number of remaining seats and the estimate of how many people might reject the admits by the deposit due date (May 27th). Also, some people might ask for deferrals too, increasing the number of available slots.
The ad com confirmed that they do not anticipate to invite for interviews all applicants from extended R3.
I guess the best thing everyone can do is just to be patient and wait for some news. Good luck to everyone!
