I think I spoke incorrectly, I was referring to the second wave of the early admissions that someone else had referenced in another thread! I got my offer on Feb 16 and my deadline to accept is March 12 - I think my acceptance was still technically an early admit (I wrote the Jan LSAT), so there definitely should be more acceptances before they send out waitlist information. Plus I saw that they have sent out invitations for the interviews for people in the IC category. (Honestly I'm not sure if this information is helpful or not, but I hope it is!)
I don't think March 12th deadline for those applicants was a second wave, I think it was a continuation of the first one as they adjusted for fall grades and considered Jan LSAT. I still think in March there will be a second wave, probably sometime next week and again after the 12th and then the waitlist. That seems like the most logical to me. What do you guys think?
