Your emphasis should be on going to a place that’s affordable and that you want to be.
Brown has an open curriculum. Columbia is in Manhattan. Duke - is suburban if you will and is gorgeous but has a somewhat split campus (they house a bit away). Which is right for you.
I don’t love your chances at any - but that’s a reality of these schools. You’re a wonderful student.
I do worry that you think you’ll get more credit toward your degree from AP and DE than you actually will.
Thanks
