Picking classes for senior year, prospective CS major - too late?

I was thinking of AP Physics 2 instead of AP Chem. I’m more interested in physics and would’ve just taken it, if not for my lack of dedicated biology and chemistry courses.

I chose stats because it’s one of the relatively few remaining course options that interest me, not for rigor, but I’m slightly worried about the additional workload on top of AP Calc BC.
