What high school cles should a marketing manager take?

I am only a freshman but i am curious. I want to me a Marketing Manager because i like giving speeches and I am really good at math. I just have no clue what cles should i take to kinda help with scholarships and stuff. for math this year i am in algebra 2, then pre cal as a sopre, then calculus and then i will probably end up taking stastics as a senor. but like what electives should I take? Should i continue doing debate? ( i am in debate right now)
