Hmmm. When did you take the LSAT? I took it last February. I'll give you a run-down of my waivers:
UMich - waiver specifically mentions me being a resident, so that probably played a role
Penn - letter from their gay dean telling me how gay friendly the school is
Notre Dame - fee reduction email, very weird
Northwestern - email out of the blue
Duke, Vandy - USPS out of the blue
I've gotten countless other waivers from tier 2 and below. I only applied to Cardozo. I have no idea why. None. I guess I was just in a weird mood that day...
I'll be keeping an eye on you too. Best of luck!
