Working, watching all I can, playing silly little games like Doctor Who legacy and, of course, this website. I haven't participated too much in the forums, but I have to say that reading everyone's comments and hopes and regrets makes the wait easier for me. I don't have any friends applying to grad school--they did last year, all in Europe, and they all got in--so this website helps me know I'm not alone. I don't know about you guys, but I don't really have much people willing to hear about my panicking!
That said, best of luck to you all!
