Ideally AOs will want a good grade in calc for this.
But as others say, if you don’t get in you will never know why. The vast vast vast majority of student don’t get in to these schools and majority of candidates are remarkable students.
I do alum interviews for an ivy, i see truly amazing students turned away each year.
Good luck!! It is a rough process and just make sure you have good target/safeties too. You never know:)
