Which college do you think is best?

I have had an extreme desire to be an oncologist since I was 9 [now 14], I have been wanting to go to UCLA of Merced for a while, but we recently took a trip up to Indiana and my parents were talking about how good of a school Purdue University is. The main reason I am going to UCLA, is because me and my best friend have planned on going down there together when we turn eighteen, and have fun. Of course, I'd be serious when needed and everything. Which college do you think would be best for me? Which college would you go to? Thanks so much! :)
