I think these e-mails are often sent out to manipulate the rankings. They just want you to apply so they can reject you and make it look like they rejected more applicants. ...
Funny thing about that. I applied to CWRU and even though I wasn't a lock, I was in the realm of reason as far as an applicant. (LSAT right in the middle and gpa on the lower end.)
Got rejected immediately.
A few weeks later, they called back to ask if I had decided on a law school, and if I hadn't, that they would re-activate my application.
Methinks they rejected me a bit prematurely and when they flood of super qualified applicants didn't appear in the numbers they had hoped, they started backpedalling a bit.
By then, though, I was already accepted somewhere else with a scholarship. I should have had them take another look at my app, just to see if I could get an acceptance, though.
