There is an unending list of things you can choose to do during the weekends. According to some of my friends studying there, you can choose to do the following things.

• You can enroll in the NCC and their respective sessions held on every Sunday.
• Besides, you can also attend the free session, named “ Heartfulness” meditation classes located at Hiran Magri, Sector- 5 (the landmark of which is the S.S English Coaching Center) held every Sunday.
• If you are thoroughly inclined towards sports, you can visit the university sports ground every Sunday.
• If you are passionate about reading books, then you can visit the Central Library of the university every weekend. 

The moral is to spend time relentlessly well, and avoiding unnecessary banters that could lead to spending time in a rather futile way.
