Well, I'm only a Junior, so its a bit early in the process, but these are the colleges I checked out and a bit of what I think about them:
Columbia: Well, its in NYC, but not in downtown Manhatten, so its pretty safe. Unlike NYU, it actually has a campus (The largest privatly owned open space in NYC). The campus was amazing, as were the buildings, but I thought the students were a little too sure of themselves, and the security was a bit extreme (getting carded at all the doors, security goons everywhere), but thats what you get in NYC. The school is about 4000, as big as my highschool.
NYU: This place was great, but it doesnt actually have a campus, just a lot of scattered buildings. Thier housing is absolutly amazing, with appartment style dorms on 5th ave, riverside view dorms, everything. Only problem is, there are 16000 kids, so even on the tour I felt like just another number. They have a really strong computer science program, which I'm interested in, but actually getting into said program is troublesome, because it is actually a seperate entity from the rest of the school. Its... well... suffice to say NYU is proped up by a sprawling beurocracy. But its pretty cool. It just lacks rolling hills and a big lawn.
Sarah Lawrence: I took the train to get here. Its... tiny. 1200 students, 90% female (lots of dating opertunities). They have a tiny tiny acceptance rate. 3200 applicants for 300 slots = oh my. Also, they have a tiny computer science program, with but 2 teachers. On the other hand, the teachers are amazing, the courses are interesting to the point of obsession, and the campus is beautiful. Plus, the food is excelent, being only served to some 500ish people (multiple dining halls), rather than the scary food they have at the monstrous NYU. A final note: unlike any of the other schools I looked at, SL has no major, no fixed classes, nothing. You have a single teacher that guides and focuses you, but... you dont actually have to take any specific course ever.
And finally:
Carnegie Mellon: This place rocks. I mean, you cant go wrong with an Engeneering school that swallowed a fine arts school. The facilities are almost all new, or newly renovated, so they absolutly rock. The students were really friendly, and the administration seemed pretty relaxed. There is a reasonable greek life on campus, but its not overwhelming, the school being mostly geeks. I got a one on one tour of the place, and my guide was pretty honest about everything. Some of the buildings have a few quirks, mostly because the school is built on a series of hills, so the 7th floor of the Comp Sci building connects with the second floor of the double-E building, and the second floor fo the Comp sci building connects with the third or fourth floor of the New Comp Sci building. So you can walk into the double E building, go up a flight of steps, cross a skybridge, go down five flights of steps, cross another skybridge, go down three or four flights of steps, and walk out onto ground level. Fun. Anyway... CMU has probably the best computer science programs in the world, along wiht four or five excelent graduate programs in Computer Science. Its... super cool.
Wow... well, thats my college visits. I did some other stuff too, lots of broadway shows and a Yankees game (the one the lost on sunday.... grrr) ... but that can wait for another post.
