here are more than 15 clubs are there in rit. Almost all clubs work in the same way, but choosing a club depends on your interest. If your interested in becoming entrepreneur then I recommend EDC, one of the biggest club. Where you can learn how to approach people(sponsorship team), organizing and managing an events, a few technical stuff.
There are other clubs like dance club, robotics, math, if you are into social services NSS, tedx, even quara.
Joining clubs helps us expand our friendship with other branch students and it’s best opportunity to meet our seniors. (It’s hard to find them in class :)) hope this will help you!!! All the best
