I'm currently 15 years old, and have owned and operated a business for 4 years. I'm a Sophomore in High School right now, and I'm wanting to know what classes I should take as a Junior and Senior to help me get a Business Major in college. What should I do on my own to help me get more experience besides my small fish business? I don't mind working long hours, and I'm really good at speaking to the public if that helps.

Thank you!
