They still do acceptances in January. Last year, they broke from the regular Tuesday schedule and did acceptances on Wednesday, Jan 19 in the morning, and then they did Final Pool on Thursday, Jan 27. The previous year, they also did Final Pool on Jan 27, which was a Wednesday.
Based on the last two years, the final round of rolling admissions acceptances will go out tomorrow or Wednesday, and then pretty much everyone else will hear on Jan 27 that they are in the Final Pool.
Just based on the last 2 years though, so it could deviate a bit!
