I am sorry to hear that you've had to go through this situation with Seton Hall. I was waitlisted there too (apparently a 3.78 for their median 3.14 gpa isnt good enough). When I have spoken to them about the waitlist, they have seemed pretty disorganized and vague. It actually took them three times to send me my waitlist letter before I received it (and I live 20 minutes from the school), and then they accepted me into their evening division, which I had specifically stated that I did not want to be in. I think their whole process has been very bizarre. If you think it will help your situation, then call them; but it does seem that once schools make their decisions, that is it.
