A while back, I read all 86 pages of the Fall 2015 thread and noted down the dates that people got admission notifications. So far, it has correctly predicted the dates of when I would hear back from my 4 schools, give or take one day due to some days falling on a weekend this calendar year.
Minnesota: 1/7, 1/13, 1/16, 1/29 (I heard back on 1/3)
GWU: 1/4, 1/6, 1/12, 1/13, 1/30 (I heard back on 1/4, spot on!)
Emory: 1/6, 1/18, 1/26, 1/28, 2/2, 2/4, 2/11, 2/21 (I heard back on 1/19, one day off)
Boston: 1/21, 2/2, 2/12 (I heard back on 1/22, one day off)
Here are the upcoming dates:
Columbia: 2/6, 2/10, 2/25
Berkeley: 1/29, 2/9, 2/14
Michigan: 2/11, 3/1
UNC: 2/13, 2/18
Yale: 2/6
Washington: 2/9, 2/19
JHU: 3/4, 3/19, 3/31
Some takeaways: Last year, Columbia had a huge spurt of decisions released on the first Friday of February. If nothing major has changed, we should expect the same this year. Johns Hopkins takes their time with decisions. They do get the most applications though so its understandable.
Hope this helps someone!
