If this is true, you had some bad information going into all of this. Even though you have a Duke connection with terrific test scores, Duke is a reach for everyone that isn’t a recruited athlete or the child of someone incredibly famous. Also, Duke has no shortage of applicants from very rigorous private schools that have higher UW GPAs than you do.
Your profile is terrific, and I still think you will get into at least one very selective school, but you have to be realistic about this goofy process. People you will never meet, with biases & preferences you will never know, are “shaping” a class based on preconceived plans that will never be made clear to you.
