Course Selection/Scheduling

I was thinking about computer science as a major. I took honors world history freshman year and APUSH sophomore year. I could take IB History of Europe instead of Psychology if needed tho, but I thought Psychology might be more interesting. I could do full IB but that would mean I would have to take IB Bio (and have no physics experience since it’s the only science my school offers) and I couldn’t take AP Computer Science which would give me experience in my major. But, what do you think?
