Orgs to join that is related to Business Administration or Business-related orgs

Hello! I am an incoming first year student at UST and I’d like to know if there are any orgs that business as a whole! My program now is BSBA Major in Business Economics, so an org that even more related to that is great to know.

If there are other orgs that is in the same stratosphere as what I have mentioned, please feel free to tell me😁

Thank you so much!
