One of my friends is a student at Thapar University, and here are some of the things that I heard from him. This is subjective and hence may vary from one person to another.

• The official time for entry at the boys' hostel is 10 pm. However, if you maintain a good relationship with the security guard at the hostel gate, you can roam around the campus at any time of the night.
• The COS road is the most preferred one for going to the hostels. The reason is unknown though.
• After college, hanging around nearby momo stalls or any other stalls is better than hanging around at the college canteen.
• Irrespective of how much distance you travel, the fare for the rickshaw/ e-rickshaw remains the same which is Rs. 10.
• If there is a Lab class right after the lunch break, then you still have got 10 extra minutes to chill.
• The lab teacher may appoint ME students for evaluation so you should always be nice to the ME students.
• Some teachers are known for detaining students even in their 7th semester, never mess with them.

These are some of the things that you should keep in mind.
