Which sciences should I take?

I'm going to be in gr.11 next year and I am offered 3 science courses, but only want to take 2. I am offered chemistry20, biology20, and physics20. I don't like math because it takes me a long time to finish but I know I'll need to use it in these courses. I do have over an 80 average in school. I am thinking about doing something like therapy, or something to do with health, but most likely have an occupation with MUSIC in the future. which courses should I take?
