To be a good doctor

These days I tried to study hard in Chinese Medicine. But I find there are so many things to memorize to become a good doctor. It's so hard for me because I am too old to do this. And In this school I need to pay so much time to pass many boring and useless subjects such as chemical and Chinese. I don't think it's a good policy to force a student to take the useless subject to waste his time. In my viewpoint, a school need to provide many courses for students to choose by their will, not to force to choose fixed course.But it's hard to carry out because a school don't want to hire so many teacher to add his cost.
