I do Separate Sciences, French, History (For my options); Separate Sciences is good 8 extra hours of science in either Chemistry, Biology or Physics (Interchange every few weeks). French is okay, I find it easy as I find it more fun/'flamboyant' than Spanish (I would of loved to choose German, but my school does not have any permanent German teachers). History is also okay, currently learning about medicine and public health over the ages (First test for history coming up in June); after that I will be learning about the American Revolution and I forgot the last topic for history.
For your subjects: German: Good, Germany is becoming a leading economic country along with the likes of China, Geog: Can't comment did not choose, History: Learning about past medicines and public health could be use to you and Business: I personally think not really useful for becoming a Doctor.
I would recommend you choose Sep. Science if you want a job in the field of doctoring. Gives you a wide job variety and some knowledge.
