Emory also has ED2, which is allowable under BC’s EA rules.
My understanding is that in the past, BC’s acceptance rate for EA was very similar to the RD rate, albeit with a different type of pool. However, for class of 2022, the RD rate was notably lower than EA (maybe they were surprised with the RD app numbers?). EA was 31%, but if a third of EA applicants were deferred to RD as in the past, RD was probably around 22%. I don’t think BC published what portion was deferred this year.
