P.S. This is what I think Southwestern is trying to do: Since they are trying to better the reputation of their law school & raise their rankings, they are waiting to receive all application before making decisions about non-auto admit applications. Everyone who has been admitted thus far, has been an auto admit. So I think they are waiting to see what their application pool will be like before making decisions about non-auto admits.
If this is truly the case, they are not really using rolling admissions & it doesn't matter when you applied to Southwestern. I am an example of that. I turned my app in on 11/7 & people who turned in their app after me have already been admitted.
