BC Calc and Chem: Use an AP exemption or take the class?

[skieurope]

My question isn’t about the rules of the particular schools, which we had found, but about the practicalities.

There is no one-size-fits-all answer. Depending on the college, intro calc/chem classes will be similar to AP classes or may be more advanced, covering more breadth/depth. Without looking at old syllabi/exams, nobody can say for certain unless they have familiarity with the college in question.
