Is Cornell a good school to go to if I want to become a neurosurgeon?

I want to become a neurosurgeon. I was wondering if Cornell is a good school to go to. It has ties with Sloan Kettering and NY Presbyterian, and it's in New York which is very convenient. But is that school good enough? What other schools should I consider preparing for? Im just entering high school, but I've gotten all A's my entire life. I just need to know so I can workhard enough because this is something I need to accomplish.
