Student, Princeton University, Class of 2018,
It's financial aid is killer. College these days isn't affordable, but Princeton helps you with that. On top of that, there is a good amount of funding available for you to study non-traditional subjects or go abroad if you are willing to look a bit for it.
Diversity of interests. Yes, a good portion end up going into banking/consulting, but as an engineer who was choosing between Princeton and MIT, I constantly am thankful for choosing Princeton because of the diversity of the student body when it comes to personalities and extracurricular interests. If I want to talk tech, there is a crowd for that. If I want to be challenged in my perspectives on literary, social, political issues, there are people I love to talk to about that. Princeton has a crowd for anyone.
It's pretty and quiet. It's not nearly as interesting as living in the city to be sure, but during the semester, I need all the help I can get to focus, and the town is good for that. Plus there are free or cheap tickets organized by the residential colleges to see Broadway shows if you are interested in going into the city!
