Any Asian boys out there who took Calc BC senior year and got into top engineering schools?

They really don’t care that much if you had Calculus III etc. in high school. They are looking at your grades, test scores, and ECs.

I tutored a white girl who didn’t have BC calculus and needed a lot of lessons to get As in AB Calculus and a top math level II score. The only place she was outright rejected was MIT. So I would say not having BC Calculus and not being at a top level with math might be a problem for top engineering schools.
