What to do about Physics?

Hey everyone.

I’m currently a sophomore in high school and scheduling for next year is near. Here’s my predicament:
I am interested in majoring in an engineering/physics field in college and I know that taking AP Physics C is almost a requirement for this. However, my school does not offer an AP Physics C course, and only an AP Physics B and IB Physics SL course (no HL). I do plan on taking the Physics C SAT and AP test. I was planning on taking IB Physics SL junior year. But I’m not sure what to take in senior year. Do I self study Physics C in senior year? What should I do?
