I should have mentioned that I am a big fan of Joe Biden. Really though, you mean to tell me this wasn't what everybody else was thinking. I am bad enough myself with how often I check my e-mail hoping for good news out of Ithaca, but we have kids on here who are practically having asthma attacks everytime they see the words "law" and/or "school" in an e-mail message. So, like I said earlier, somebody who actually gives a damn (maybe not to that extreme) would be more deserving. I don't even think this guy sent in a LOCI because he didn't even remember he was on hold or reserve. That is something to say wow about, not what I said.
My advice would be this: you wanted to go to France and you wanted to go to Berkeley... do both. You have a sufficient background to accomplish that if you wait until next cycle and don't apply after the rush of applicants in an overloaded year. However, in a year where seats per applicant are in such low supply why would you take a seat from somebody who actually wanted to attend the school.
My other advice is figure out where or what you want to practice: You applied to Berkeley, Cornell, and GW with nothing in between. Norcal, Ithaca, and Washington, DC... what do these places or institutions have in common. Nothing, absolutely nothing. That bothers me. That really, really, really, really bothers me. Maybe I could understand the connection between Berkeley and Cornell as both would lend themselves to diverse specialties, they are both liberal strong holds, and maybe you are into outdoors and winter sports. Are any of these things true about GW? No. I am doing you a favor by pointing out how obtuse your assertions are. You will be spending over a hundred thousand dollars and three years of your life on law school. So with that in mind, I would sit down and make an educated decision based upon the following factors:
Location, Finances, Placement, Specialties, Political Culture, and the opportunity cost of deferring a year so that you can attend Berkeley (or another top ten school) or attending GW instead.
I am sure that I am leaving some things out, but with that last consideration in mind you may very well determine that you should accept the offer from Cornell... you might be looking for liberal politics, simply want the prestige for your family (if you are travelling that much and you are willing to make a hundred thousand dollar plus decision on a dime then maybe you have money to play with), be interested in international or labor law, want a small campus environment, want to place in a big city, and are willing to take the risk of Cornell's 93% placement after 9 months for graduates (since they are competing ITE against the rest of the Ivy league and NYU). All I am saying is figure it out.
