Realistically, what are my chances to get into MIT or Harvard?

So, I came to the United States almost two years ago. I am originally from a minute third world country. I started school with a blank transcript, and I’ll be graduating from high school in June. I have a 4.0 unweighted GPA and a 6.94 GPA on a 7 weighted scale. My ACT is not stellar: I got a 34 in English and Reading, a 29 in Math, a 28 in Science, and a 10 on the essay (on the 1-12 scale). My subject SATs haven’t been scored yet, but I do think I’ll be above 700 in both Math 1 and Biology E. My recommendations will be pretty good, I’d say, but my extracurricular involvement is, at best, lacking because I live in a very remote area. I do constantly tutor people and I compete in a couple of academic competitions that only go up to the state level. For what they cost, the only two top schools that I would really love to attend are Harvard and MIT. I, thus, only applied to those two besides other schools where I knew I’d get in (and I did!<3) The interview for MIT went, I think, great. I guess I just want to relieve the anxiety and all by trying to predict the future. In all honesty, what do y’all think?

If you have a 29 math and 28 science, what are you planning to study in MIT?
