Expenses of Delhi University

So , i am not a student of DU , but wanted to know about the living and day to day expenses. Like how much does it cost to rent a room , do we need to share it and what is the condition of those rooms, is it safe enough.

Is it easy to find some type of job near the university(waiter, receptionist etc.), is it easy to manage collage while working???

Does any of you ever faced ragging or bullying of anyway ??? (17F)
