<p>First of all, congratulations on all your acceptances! You have a very impressive list.</p>
<p>Now, if I may be so bold as to say so... it seems to me as if you've approached your college search / applications process with the wrong attitude. Your question should not be "Picking the Right Ivy League School" but rather "Picking the Right School for Me." If you haven't even visited any of the schools and don't already know what it is that you like about each of them (besides that they are prestigeous), then it looks to me like you have just applied to all the Ivies without considering how they fit you and what they could offer you besides a name-brand education.</p>
<p>Now, it's possible I've got you completely wrong, and that you applied to each of these schools for a specific and personal reason. If so, good for you! But if not... maybe you should consider changing your attitude about college a little bit.</p>
<p>As aidnked says, each of these schools has something to offer. Research each one, and visit as many as you can, asking yourself, "what can this school offer ME? Will this be an environment where I can have the college experience that I want?"</p>
<p>You asked "What determines 'fit'?" Here is another list of things to consider (many of these things aidnked already mentioned):
--the academic philosophy of the school (contrast Brown's complete academic freedom and student responsibility for education with Columbia's core curriculum)
--the academic programs (is the school strong in the department(s) that interest(s) you?)
--other academic opportunities (design your own major, double major, cross-registration with music / art schools, etc. Contrast how Brown strongly encourages study abroad, while Harvard generally takes the attitude, "we are the best school in the world, so why would you leave?")
--extracurricular activities (is there something you really want to do in college like sing in a chorus, play rugby, go clubbing in a big city, volunteer to help the homeless? Find out which college is the best place for whatever interests you)
--attitude of the students toward the school (are the students happy where they are? Did they pick the school for its name, or because it was a good personal fit?)
--social life (contrast Dartmouth, where most students stay on campus and drink, with Columbia, where a lot of the social life takes place off campus in the city, etc)</p>
<p>I'm currently a student at Brown, so I'd be happy to answer any questions you have about my experience here.</p>
<p>I'm sorry if this post comes off as sounding like a lecture. It's not intended to be at all. I just hope that you find a school that you can say to yourself every day, "I LOVE this place! I love these people! I love what I'm studying!" That's how I feel at Brown, and I would wish that experience for you, wherever you end up.</p>
<p>Best of luck!</p>
