These are not matches for anyone, anymore.
I won’t comment on all the starting businesses and working with investment managers stuff which has been covered extensively.
re: courses.
If you really want top finance programs you almost certainly need AP Calc BC (if offered at your school) or at least a year of Calculus, which I am sure is offered at your school if they have all those APs. Stats instead of Calc could be a huge ding against you given your interest.
I will reiterate top schools want kids with a high degree of intellectual curiosity and ability to explore new areas - make connections between topics and have a high degree of creativity and collaboration. They also see right through kids checking boxes. They don’t want a staff member, they want a student.
Also, not sure if you need FA, maybe not, but being an international student adds complexity to that.
