Should I drop IB Chemistry next semester?

Right now, I have a C in IB Chemistry (finished my final…) and I want to know if it is a good idea for me to drop down to the regular level. I am planning on majoring in politics and economics in college. Current sophomore right now.

I tried to take APUSH this semester, but it has really killed me (teacher was nice enough to not give me a grade for the class and make sure I get my credits for us history) and I am going to the normal level next semester. I might try APWH online next year since my school doesn’t offer APWH. I want a higher gpa so should I drop IB Chemistry? Thanks!
