So most people have probably heard of the University. I'll just throw in my two cents as far as what I found interesting about the school and it's resources.
Make sure to take classes in other colleges. The teaching styles of the professors vary widely and there are always great classes to take. Ask around about good classes and professors.
Definitely go gorge diving. Despite being frowned upon by the university, it is something every Cornellian should do. In addition, make sure to attend a Cornell Hockey game. I came to cornell not liking hockey so much and left as a huge fan. Even if you don't like hockey, you'll be amazed at the atmosphere and school spirit shown at the games.
The education you receive is going to depend on what you put in. As Cornell's first President, Andrew Dickson White, said "you are not here to be made, you are here to make yourselves."
Cornell has myriad clubs and organizations on campus. Make sure to get involved in some of them because they add a huge amount to your education.
