I emailed then and they said that they made a first round of admissions and rejections, if you are not in none you are in the WL. In addition, they said that their plan is to contact all remaining applicants around mid-March.
I believe that if we don't received anything we are in the waitlist, also I heard that the things for who are in the waitlist will be more clear in early April.
May I ask you if you accepted?
