Maybe they got a lot of no's so they're scrambling to find the people on the list to send acceptances to? Did you have an interview? Someone wrote that they didn't so I'm guessing (and hoping) that whoever had interviews will just be waitlisted or accepted once those first round of people pay. But idk!
This is all sooo stressful! Did she really say "accepted?" I wonder if they are just waitlisting everyone else, but if that's true why not just tell us now instead of waiting? When I called on 5/2 she asked for my name then said we'll find out via mail by May 10, so I take that as a bad indication.
