Congratulations on making yourself a very strong candidate!
The college counselor at your boarding school is probably best placed to chance you for the schools you are interested in, as the counselor will know details about your school and how it performs at the schools of interest and how students like you from the school have performed in the past.
Are you going into your junior year, or are you already a junior and you’ll be going into your senior year?
I suspect that places like UCB, UCLA, Stanford, and the Boston schools can also have high rents, just as NYC does, at least based on the prices of housing.
I’ll think more about your stated desires and will return with some school suggestions.
