Dropping AP class 2nd semester? Would it look bad?

So I am a junior in high school. I’m taking 10 credits this semester (a full schedule is 7) and that includes 4 AP classes (English Lang, Physics, Calculus, and Biology).

Right now I am struggling really badly in AP Physics. The teacher doesn’t know how to teach very well (it’s their first year as a teacher) and besides that I’m just not really understanding the material. Also, we don’t ever do anything in class and I kind of feel like it’s a waste of time, especially because I always have other things I could be doing.

I want to know if it would be okay to drop AP Physics after the first semester is over? It is too late to withdraw without it showing up on my transcript, but would they notice if I only took one semester? I am already taking a different class that fulfills my science strand C, so I only took physics because I thought it would be beneficial. I have an A in the class right now, and I think I could keep it that way, but I don’t think I would be able to handle a second semester. Would it look bad if I dropped it and replaced it with a different class? (I was thinking piano IV or getting Econ/gov out of the way online)

I just feel like it’s stressing me out more than it should, and I already have a lot on my plate. What should I do? Any advice would be helpful.

Two lab sciences is a lot. Can you drop to honors/regular Physics? I would make sure to get Physics in HS at some point. I would not think that colleges would look down on only taking one science at a time esp if you are taking calculus as a junior.
