How could I improve my chances of getting into Cornell University?

Your qualifications seem to be on par with others that would be applying to Ivy League Colleges. A few things that would help you out would obviously be an SAT score of AT LEAST 2100, considering the average is around that. Cornell, just like all the Ivies are reaches for everyone, no matter what your qualifications are. The only way to be 100% sure is to apply. Write a killer essay that shows them why they can’t live without you on their campus and you should be good. Best of luck with your application!

Chance back, please?
