SAT II Chem vs. Physics

I’m not exactly sure which one I should take. I’m in Honors Chem right now, but next year I will be taking AP Physics. Would the AP class help me more with the subject test or does that really not matter? Plus, my teacher in chem isn’t the greatest teacher and she’s not very thorough, and I feel like that might be a disadvantage.
I also plan to major in Computer Science if that would affect anything

CS majors should be able to submit either the SAT Chemistry or Physics. Hard to say if you’d perform better on Chem or Physics (but if it’s AP Physics 1, you’d have to study E&M and other topics on your own). Have you taken any practice Chem tests?
