So it is premature at this point to assess exactly where it will make sense for you to apply. Keep doing your reasonable best in your classes, same with the SAT, make sure to leave time for your most valued activities as well as your social, emotional, physical, and ethical development, and next summer/early fall we can help you understand your general competitiveness.
I would also suggest you devote some additional time now to exploring all the many different great college options in the US. If you can visit a reasonable sampling of schools in person, even just locally (there are certainly a lot in MA), you may find that helpful in terms of helping you focus on what really matters most to you. You can definitely explore them online as well, digging into things like departmental pages, activities pages, scholarship pages, and so on.
Again if you would like help generating leads to explore, this community is great for that. Like if you explain more abut what you like about MIT, we can help you find more colleges to explore that have at least some similar strengths. It can help if you give us an idea of your budget, which is a conversation you should be having with your parents.
I’m confident if you do your reasonable best academically, keep developing holistically, and then explore your college options with an open mind, you will end up with a well-balanced list of colleges that all make a lot of sense for you in light of your academic interests, budget as relevant, and other preferences and goals for a four-year college experience. Then you should end up with multiple interesting offers to consider, and you can choose the offer you find most exciting, and you are off to college.
As a final thought, many people here don’t think much of generic lists like “T20” or “Ivy”. That includes me. It is possible that a great list for you will include some such colleges. I doubt it will include all of them, and it will definitely include a lot of other colleges not on those lists. To be very blunt, I think people use those sorts of generic lists because they just don’t know that much about colleges in the US, and they lean on such lists to try to simplify things.
Fortunately, with the help of communities like this one, you have plenty of time to learn everything you will need to know to have a much more sophisticated list, one that actually makes sense for you as an individual. And not only does that prevent you from wasting time applying to colleges that don’t make sense for you, and missing great colleges that do make sense for you, it also means when it comes time to do things like write “Why us?” essays, you are not going to be one of the kids who doesn’t know what to say, or feels like they have to try to make up something the college wants to hear. You’ll already have a great answer ready to go, because your process will have been about that sort of reflection all along.
