<p>I got into all the schools you listed except Princeton, but I've visited the school enough to know about it pretty well. I wound up choosing Penn over everything -- if I could do it again, I would have chosen Harvard, Yale, or Stanford. Probably Stanford.</p>
<p>Most of the important points I think have already been mentioned in this thread so far, but this was basically my own rationale for each school:</p>
<p>H: Obviously a great school, but the location was iffy and there were too many arrogant prestige-whores.
Y: Again, obviously a great school, but the location was also iffy, and there was a lot of focus on the humanities, as someone else said.<br>
P: Amazing campus... so incredibly peaceful/tranquil, but absolutely nothing to do outside of the Nassau area, really. An extremely competitive choice f education is your top priority, here -- the focus is great and the school's faculty are helpful.
C: Decent location -- lots to do in NYC, but the campus is small and probably very easy to get tired of. The Core seemed interesting at the time, but it probably wasn't for me.
S: Amazing education, amazing location, amazing campus... I honestly couldn't find too many faults with it other than the fact it was on the west coast (and I had been trying to get OFF the west coast).</p>
<p>I wound up choosing Penn because it was central in location (I can go to Princeton or New York relatively quickly), had very flexible degree options, was close to Princeton, had Wharton, and had a huge student body. I've since come to find that I should have thought ahead a bit better. </p>
<p>Don't choose a school based on prestige, but don't ignore what's important to you, either. Eliminate schools from your list that have little overlap with your true academic interests, and give preference to those that to. Then choose the schools you can see yourself being happy at (this will, in turn, allow you to do better in your studies). Here at Penn, I dislike what I study, and I dislike the campus, the faculty, and many other things. All in all, it's a huge motivation-killer. So be sure to not make the same mistake and choose based on best fit and overall happiness.</p>
