Dang that's crazy early. I would have thought it would be in may or something. I wonder when waitlisted people will find out if they got a spot or not.I believe those who were accepted around March 5th were originally given until March 20th to commit, and then that was extended for all to the 26th.
After that I think it just depended on if someone was able to get a personal extension. Mine was only a couple of days, though.
I hope you hear something soon!!
