One of my friends studied at Hansraj College, therefore I am quite familiar with it. Let me share his orientation at the college. 

• The one thing that can be assured is that you will have the best 3 years of your life here.
• The orientation in colleges is basically to make the freshers familiarize with the college. 
• It includes an address by the Principal and other senior faculty members. 
• There will be some performances like Ganesh Vandana, dance, singing, etc. by the college societies. 
• The annual magazine ‘Hans’ will also be launched which contains the previous year’s events and achievements by the college.

Make sure you attend the orientation. It's a great step towards interacting with people. You will get to know about your college history, facilities, societies, leisure joints, etc. Also, you will not have any difficulty in finding the room for your classes the next day since you will already be familiar with the building.
