Oh god, I didn't know. I guess she didn't get in, then. :( But good luck!
edit: she was waitlisted. got into 11/12 colleges besides williams, including dartmouth, amherst, bowdoin, ucla, pomona, and berkeley. i've heard the perspective of "chill out about undergrad" from a bunch of people and as much as i still kind of have the feeling of "no, fuck it, i'm going to try really heard to get into where i think i'll be the least miserable", it's good to know in the back of my mind that i'll probably be okay in any school that's in my bubble of requirements. i mean, the irony of consoling somebody about not getting into their specific school when they got into some of the best places in the nation -- i do feel for her, but there's a somber quality to the whole thing that is vaguely funny when you think of how much opportunity we all have.
Paranoia Survivor, I personally think that both Brown and Pomona are better than Tufts -- I don't want to make a unilateral declaration, but that's what I've heard, especially for humanities majors. Pomona is also much much smaller than Brown, so you'd have to consider whether you'd rather attend a smaller school than a big one. The only thing I'd have to say about that is a small school may seem alluring at first, but it can be disconcerting not feeling like there's lots of stuff going on, and it can be hard to find people who are like you and you can understand/bond with. There are general requirements at Pomona, while Brown has a completely open curriculum, which is both daunting and freeing. When I visited Brown, I got the sense that the school had a very good academic atmosphere, and was extremely "well-rounded" -- if you don't have one very particular interest and are interested in lots of different things, I'd recommend it; I personally wanted something that was more specialized. I've heard nothing but good things about Pomona's academics. The stereotype of Brown students seems to be that they're very happy, open-minded, unpretentious, and pleased to be there just for the sake of being there. My visit confirmed that. Pomona students, I've heard, are a bit more competitive and potentially a little more stuck-up -- Brown does a lot to reduce the fiercely competitive spirit on its campus. But ask around, read reviews, etc. They're both good choices -- in fact, all of these are very good schools. Oh, also, Brown has a much nicer college town than Pomona; Claremont is supposed to be pretty terrible, so students just generally hang out on campus. (Ik this assessment seems to really be tipped in Brown's favor, but I'm actually not going to apply since I wanted something smaller and more specialized like Pomona; you can juggle all of these factors for yourself).
