I'm only aware of schools providing these three courses as independent of each other. Which makes sense, since they are independent.
I took Chem as a sophomore, Physics as a freshman, AP Chem as a senior, and AP Physics as a senior. I didn't take a single bio course after 7th grade.
For what it's worth, both Calculus courses were harder IMO than any of the aforementioned.
