Is DTU ragging free?

Yes, DTU is a completely ragging-free campus, and the kind of mistreatment against juniors is reprimanded. 

My friend shared her first-day experience at DTU. She arrived late and missed the orientation so had no idea where the classroom and hostel were. She was flustered and roamed around looking for her class for about 30 minutes. After losing all hopes she finally mustered the courage and approached a group of seniors and asked them about her class. One of them asked for her registration number and then searched the schedule on the official website. He then told her the exact directions to her class. He also gave his phone number and told her to contact him if she faced any issues in the future.

This anecdote alone proves that DTU is a ragging-free campus with extremely helpful seniors.
