Since Cornell is fifth on your list, please do not apply ED without first visiting. Although never done by any self respecting CC poster, I am going to venture to say that if you apply ED to Cornell, you will get in.
I would suggest you apply REA to Stanford. They will appreciate your Young Arts win and your huge entrepreneurial achievements. As a strong writer, you can hit your essays out of the park. I think you’d have a good shot there. Plus, it is your first choice.
