What to major in the university and which courses are recommended in high school?

Its nice that you think you know what you like now, but honestly changes definitely happen in college when you get more deeply involved in the subject. For now enjoy the time you have and focus on taking challenging courses that can get you into a good college. And then take exploratory classes so you can get a feel for more of what you like and don't. Nothing in high school really applies to a college level course or could prepare you besides ap/honor/ibu programs or classes. Just because they do push the limit so much. If you're interested in bio and soc, you might be interested in talking to a career counselor at school because that's what they are trained to do. Help you find what you're interested in and maybe find some programs that test out your strengths. Good luck, don't forget to enjoy the teen years. They seem to pass fast :]
