University application, how far could I go?

Your resume seems very impressive, and it looks like you have a very good chance of being accepted into a big name school. Colleges love to see a well rounded student, and you seem to be strong in all aspects. Make sure to write a great personal statement for applications, get good letters of recommendation and study hard for the SATs/ACTs even if you think you do not have to study. Keep up the hard work and it will pay off. My advice to you is shoot for the moon and you are bound to end up somewhere in the stars.
