I’m curious about the cost too. But with everything you wrote is makes you an exemplary student. I’m guessing you need full aid - which at many schools is far more than $70k btw. Even in state may not be free.
But given your exemplary background, if the schools agree you need full coverage they might want you. Will wait for the answer on finances.
My comment to add here is you go to a special school. The counselor there will be best equipped to let you know where you will fit in academically. They know from past students.
A school like Prarie View or Troy might give you a full ride based on merit. Or an MIT based on need.
Is an MIT (or BU or USC or Northwestern or Rucr or Miami) possible - on paper you are a stud but it’s your counselor that will better be able to make that determination than folks here in my opinion.
Good luck
