What do you think my chances are and how could I improve them?

I’m just ending my junior year of high school and I’m interested in going to MIT or Harvard. My GPA is 4.0 unweighted and 4.4 weighted. My current test scores are as follows. How likely is it for me to get in?
SAT Critical Reading: 800
SAT Math: 760
SAT Writing: 770
SAT Subject Math II: 800
SAT Subject Biology E: 730
SAT Subject Chemistry: 680

EC’s? Awards? Anything unique that you have done to set you apart from the rest of the High stat applicants?

I’m woodwind captain in marching band, and I tutor students in algebra. I’ve also been helping with coaching elementary school students for a reading competition. I believe I’m currently #2 in my class.
