Major for college?

[Lindsay Heller]

My son is a senior in high school. His post high school plans the last couple of years was to get his real estate agent license, with the ultimate goal of investing. Those two things remain the same. Now he is in a position where he could potentially go to college for little to no money on scholarships for gaming. I'm not a he must go to college type of parent. However, as a young adult it is great life experience, so if he can go for cheap, why not? 

Question is, which majors would be most useful? I understand it isn't required and could vary depending on which type of investing he gets into.  

*I joined this forum for myself, as I'm in the learning phase of my plan to use my divorce settlement to start real estate investing. Yet, here I am in typical parent fashion, making my first BP post about my child instead of myself.
