Thank god! I have been sooooo sad because I did not hear from Rockefeller today. I had talked with a professor there as his research really interested me and he had told me that he would be happy to take someone with my background and interest. I did not know what went wrong!
I applied to Cognitive Science( have worked there as a UROP for a summer-- this program is super competitive)
Yes, it is Dec. 22nd 2017. Biology is a different department than BCS so they send out invitation in different dates.
There are some people who mentioned in the grad cafe "results search" that they received interview on 22nd Dec. I am have got any notice either. Which tract in MIT BCS did you apply?
