IB Physics HL with IB Chemistry SL?

You will probably have to sleep very late everyday trying to finish your homework (let's say all the way to 1 am).

Considering you're taking IB physics HL, a good calculus backround would have been good. The lab work is also very structured in these IB science classes. It's like writing a detailed essay for each lab
