Course selection

Today was a pretty crazy day in school.  I know which courses I am going to take for the most part, except for science.  I am going to take standard level economics so that I can take higher level chemistry.  I am still deciding whether to take biology or physics.   This is a big decision.  It is basically a decision for my career path.  Do I want to be a doctor, or anything with medicine, or should I be an engineer?  I am going to take 4 maths anyways, so I should pick a subject which I can use math.  In my opinion, physics has more math that biology, so right now I am leaning toward physics.  But still, biology is a very cool subject.  The human body and how it operates, that's really interesting!  Well, I guess this wouldn't matter if I didn't enter their respective career paths...so which career path should I take?  I gotta think about this for a while....
