I want to do HL chemistry and biology. But i don't know what math course to do, at the moment I'm at an average of 5 in maths and I'm starting IB in a year but my subject choices start at the beginning of next year. My school only offers AA SL or HL and AI HL if you're taking an HL science. I'm also planning on taking english lit SL, business management SL and Spanish B SL. Do my choices seem reasonable in regards to the HL subjects?
