Got accepted in Northwestern (with 30k scholarship), UVA and Cornell (these haven't yet declared scholarships). Which should I pick?

It depends on several things such as:

- do you need the schoolarship or are you able to pay the full price 
- which school offers the best program 
- are you interested about the international fame (Cornell is an Ivy League uni)
Etc
