If it's been like 2 months you can write to them; generally if they would reject you right away they already know (which bugs me as to why they keep such people waiting till end March- anyway stupid). But then just email them. It's better than sitting in limbo.
Good luck!
It is still better than emailing the admissions committee and they are like "...our application process is not yet complete but I regret to inform you that you will not be part of the SMALL GROUP that will be chosen...". At that point I was like "so why didn't you just send the rejection letter..." of course they're waiting for March...the logic is stupid
