Math Is Fun Forum

What does it take to get into the top mathematics programs in the country for graduate school? What kind of research programs or internships should I be involved in? Is being the top student at an unknown university enough, or do you have to win national competitions and discover new math theories as an undergraduate in order to be considered for admission? I have a lot of recommendations and I'm a good standardized test taker, but I'm a non-traditional student. I worked part time and went to community college.

What do you think my chances are? If there's anyone here who got into Harvard, Stanford, Princeton, etc. how did you do it?

Thanks!
