I emailed a little while ago and they said that they're still waiting to hear back from 2 people they've extended offers to. No idea if this is still up to date, because other people have said 5/6 slots are taken. Also, no idea if these are waitlisters they're now extending offers to or still the original 6. I will say the admissions person seemed doubtful that there would be any movement before April 15th, and that most likely people would hold out until the very last second
What schools are you deciding between?
