Let’s start with where you have been accepted.
Then we’ll talk about waitlists.
If you were accepted to all of them then I would say in the Ivies…Princeton #1 for the excellent undergraduate, mentored, research experience. For the small LAC, Amherst #1, again for the excellent, broad education. I know somone who majored in Math, English and Classics at Amherst - she would have NO issues going to grad school OR getting a job.
