Whatever anyone says, a CGPA of 8.0 or higher is required to graduate. A CGPA of 10.0 is insufficient for a bright future. Try out all of the following activities.
Enroll in sports, NCC, NSS, or cultural activities that interest you from the first year. When you graduate, you'll be extremely proud of your decision. Whatever extracurricular activities are planned, simply participate and do your best. Join a leadership club that molds you and exposes you to how a leader should/will act in all situations. Most importantly, put your leadership skills to the test whenever possible.
Take your SIGs seriously and make sure you travel all over the country for project presentations. You end up improving your resume while also traveling with friends.
Finally, consider your college future as an investment in your future self. Do whatever you want. Enjoy life in the ways mentioned above.
My sister is an alumnus of the institute and these are some of the tips according to her.
Hope this helps.
