What Should I Do?

I’m currently a freshman at my local high school. My GPA is above a 4.0, I have won the title of first in the state in math, and I am also an active member of several other clubs. I am interested in attending the Gatton Academy, a special school that allows juniors and seniors to receive college credit. The problem is, the school is primarily suited for students who want to pursue a career in the STEM field. There are no opportunities to take AP courses or EC’s that I am used to. I am interested in pursuing a career in IB. I would be required to major in either a finance or business administration degree in college. Which would be the best route for me to go?
