The word “social life” barely exists in the dictionary of an MS/MTech student at IIT Madras. They spent their time holed up in labs. But some don’t want to miss out on campus life and leave no opportunity to have fun.
I have seen M.Tech students go to CFI, and participate in most events and talks like EMLs, TechSoc, LitSoc, Sports, Gym, Swimming, Art, volunteer, and some are even part of Shaastra, Saarang team.
These events are one kind of life experience and missing out on them means you are missing a major part of your college experience. Make sure you take breaks between the extensive research work and manage your time well in such a way that you can balance both extracurriculars and lab work. You will have a lot of time on your hand during vacations so make the most of it.
