What does the degree have to be?

I'm 16, and I love to study, I know that with my life, I want to be a computer software engineer, and develope applications and systems and like I never get tired of learning(This just started recently, irony in this is that I was going to drop out, but I kept procrastinating). But I would also like to go to law school and medical school(Just to learn), but to do that, I read somewhere you like have to have a bachelor's degree to go to medical school/law school, like, what do I need a degree in to go to do that after college? Like If I go and get a degree in computer science, will I need to go to college for another four years before I actually get to start law or medical school or is it any bachelors degree? Sorry if this is a dumb question o.o as I said before I didn't even think of college before so I really don't know much. Thank you for your time and answers.
