What are my chances?

I’m a high school senior who has started on college apps.
My grades have been all A’s freshman and sophomore year, and I was ranked #1 in my class in my old school
Then I went to NCSSM and got a mix of A’s and B’s (more B’s).
My cumulative GPA at NCSSM is 4.4 and at my old school, my unweighted GPA was 4.0 and my weighted GPA was a 5.0
My super scored SAT is 2190( 800 math, 710 writing, 680 reading)
My SAT Math 2 is an 800, and I will take the SAT physics October of senior year and realistically, I think I’ll get somewhere between 750-780
My EC’s include:

  1. Member of the varsity track team at NCSSM and JV team at old school and I qualified for the conference meet junior year (freshman to junior years)
  2. Founder and President of the Math Club at my old school. It was also the only math club in the school system; I helped in organizing meetings and topics as well as setting up competitions (sophomore year)
  3. Voluntary Service at local Elementary School as science olympiad coach. The team had won first place their first time in the regional competition (sophomore year)
  4. Volunteered at a local library in a summer program to foster interest in books and science for kindergarteners. I acted in plays, showed kids science experiments, set up events. (summer before junior year)
  5. Got into the research in mathematics program junior year third trimester, summer before senior year, and first-trimester senior year. My research partner and I are exploring a problem in graph theory and will be competing in Siemens and Intel.
  6. President and club council representative of the Presidential fitness club, which is a club focusing on training and dieting. (senior year)

The colleges I’m thinking about are:
MIT
Stanford
UC Berkeley
Caltech
Georgia Tech
Carnegie Mellon
NC State

What do you think my chances are at each of these?
