Every school is different. I didn’t know you could take AB and then BC til on here people mentioned. That was not our high school.
As for an IB major, U of SC and FIU are typically ratedtops for international business. IU Kelley is a top B school with not top requirements. GW and American have great programs as does Temple. One doesn’t need to be a rigid home run at any - and you have tons.
I think it goes back to - strain yourself but don’t crush yourself. You have lots of rigor and top schools in the major, stat depending, will be in reach.
Budget will be something else to look at. Do you have $400k or $200k for school. Or less ? A question to ask your folks.
