It’s way too early for you to identify colleges and especially these elite ones. Your HS GPA, SAT or ACT scores, ECs, LOR, etc will be very important factors in determining your college application list.
PLUS…you are attending a private high school, and usually these schools know what students need to do to optimize their college prospects.
You need to keep an open mind right now…and be open to exploring many different courses of study. Even in college, many (if not most) students change majors, and multiple times too.
Please make the most of your high school experiences. Enjoy what you do. Look for things that pique your interest. Do activities you enjoy. Get the best possible grades you can get.
