Great for some things, not so great for others...
IntroductionAll in all, NYU is a great school, especially if you like your major and find out what you'd like to pursue your degree in.
Campus Life and Social LifeThere is no real campus, you're pretty much smackdab in the middle of the city. So, the social life is pretty much what you make it out to be - mild or wild.
AcademicsAs far as Academics go, and I guess this can be applied to any school really, it really comes down to what major works for you, and if that school excels in catering to the needs of that major. NYU is great for business, theatre, many realms of communications, but do your research on it! Some departments really lack the heart, training, or both on how to handle individual situations.
Student BodyThe student body is a great mix of people from all over the world, always interesting people to meet. Be wary of the pretentious, the freshman dorms are usually riddled with them.
