Help with my senior year schedule!

Hi, I am having extreme difficulty deciding on my schedule this year. I want to showcase my interest in science(a long term I am hoping to go into environmental policy), but I also want a balance. The courses i am in currently are:
2. AP Calculus AB
3. Ap Biology(already take biology and marine bio) or AP Lit
4. Cotemporary world Problems(could do poly sci though it is the only senior course)
5.Spanish 4 ( Is the fourth year important?)
6.Chemistry ( could take online at college)
7. Possibly calc support
American Literature( dual enrolment) or general Biology.
Online: ( Ap government, 0.5 credits)

The problem is It would be preferable to one less class at my high school so I can take English at the community college without paying. I could drop ap bio and repeat ap literature with a new teacher, but I don’t know how that would look to colleges. I also don’t know if I want to ¨repeat¨ biology with sophomores even though its advanced. There is also the downside of my chemistry class being huge, with the majority of the 11th and 12th-grade class. I want my classes to showcase my motivation, rigor, and interests, but I also want them to be enjoyable and educational. Any advice would be helpful!
