You have to be mature to some degree, open minded, and be able to focus on your studies. You'll be forced to manage your time effectively. Other than that, I've met people who are entirely focused on their careers and people who are listless and still figuring out what they want to pursue. There really is no formula or "type" of person here. The more willing you are to try new things the more you'll get out of Cornell.

I really think there's a place at Cornell for anyone. It's big enough that it can afford to be multi-faceted and have every facet be a full, rich community in its own right. The difficulty might be in picking one community to belong to. It's definitely an academically-focused place, though, and there's not a lot of hand-holding. You should really be internally motivated, and not mind the idea of an occasional all-nighter.

ambitious, smart, focused, those who truly want to get an education, most of your classmates will wind up being important leaders some day, anyone who wants to make ALOT of money upon graduation. (important to note that cornell is made up of 7 different colleges and schools, engineering is very different from the vet school, Arts & Sciences is very differerent from Industrial and Labor Relations, it's almost hard to compare Cornell to other schools without taking into consideration the different schools within cornell

Michael
Smart people who are willing to put in the effort to succeed despite very heavy workloads, particularly in engineering. Also one must not hate cold weather.
Jade
Very academically focused, willing to live far from major cities and a larger school, independent person. Someone who can handle the cold!
Susie
Anyone. Cornell is very open to every niche. Ag students, hotel students, art and biology. It has is all. Its big, but has lots of smaller colleges, majors and departments that make it feel like home to anyone.
Toni
Someone willing to work hard to learn
Christian
Anyone who likes to be intellectually stimulated but is not afraid to have a good time.
Brittany
Someone who is an individual, willing to work hard, and not afraid of getting mediocre grades. Cornell likes to deflate grades, and the curves will help you pass, not get A's. A sense of humor and handling ego-bruising is a must. And of course the ability to have fun and handle the silliest things.
