Do I have to take the hardest courses in my school as an intl student to make an ivy league?

Umm my school offers 5 aps (Im Canadian btw), Calc, functions (pre calc), bio, physics & chem. I'm going to self study for ap micro & macro econ, then take the exams

I wanna major in econ/business & finance in uni and I really really hate science. Im aware that they are probably the most difficult courses in general but do I really have to take it especially when it has nothing to do with my major?

Im planning to take at least 1 or 2 of the sciences, is that fine?? someone please tell me I dont have to take all three T-T
