What should the president of college basketball association do, how to arrange and plan, and what should he mainly do? (explain in detail)

There is nothing to do in the college basketball association. I have participated before, and the president said that there are too many people in the association to organize group activities, so we can just go to the stadium to play and communicate with each other. Department competitions and college competitions in universities are generally arranged by students' union and departments. If it's not a big deal, there will be a last sentence every year ~ ~ ~ it still depends on strength.
