The Students’ Union actively participates in all social and cultural functions of the college. The sports events are also organised by it. The students’ Union of Sagar Mahavidyalaya started its dream journey in 2003 with a pledge to the wellbeing of the students as well as the other activities performed time to time by the college authority to run the college smoothly and successfully. The members of the union are the integral parts of the college. They actively take part in any activity of the college and try to implement it into reality is its sole motive.
