The student years are not only about books and lectures. This wonderful period of time makes students' transition(过渡) to adult life easier. Students learn how to live by themselves, and network with professors and other students. Moreover, if they choose, they can join a student organization.
One of the university's main purposes is to prepare students for an intellectual job. Student organizations' functions are consistent with that. Usually, such an association on campus carries on many projects that can have a positive impact on students' life. These can be inspirational speech events and many other non-profit activities. All these interesting projects require more than just students being present. Each of them has to go through various developments regarding management, digital design, finding sponsorships, organizing events and many others. These will be valuable enough to help them get amazing work.
Besides the material effects above, researches show joining a student organization helps psychological development. It is indeed difficult to deal with both extracurricular projects and studies. However, this routine is serious training for their adult life. They will come to understand better the importance of their lectures without which they can't complete complex tasks, so they will become more committed to their collegiate education.
Once they get involved in a student organization, however, it's more than likely that they have to spend much time participating in weekly and monthly meetings and contributing their own efforts to lots of projects. Since these activities will have a huge impact on students especially off campus, many students will place extracurricular duties above college courses.
Anyway, the impacts vary in number and effectiveness depending on students' attention. However, one thing is for certain. Such organizations will provide an unforgettable experience that will unlock their full potential and deserve a shot.
