Furthermore, you’re acting like the person who called ASU the “most uniquely successful” school in the nation wasn’t resorting to hyperbole.
This is a school that accepts 80% of the students who apply. There is nothing wrong with that and accessibility is a large part of the mission of most state schools but let’s not pretend that ASU is Princeton.
Furthermore, none of this should even be relevant in this scenario. The OP made a commitment to Duke. He/she can afford to attend Duke and abide by that commitment. It is settled then. There really should be no more room for discussion. This thread has served its purpose.
