Soon, I am going to join IIT Gandhinagar. Is it true that there is a lot of ragging in IIT?

My friend studies in IIT Gandhinagar and it is a general rule that IITians have to face some amount of ragging however, this could be true or false because he did not face any. There has not been even the mildest instance of ragging there, to date. It's good if you do not like the experience of it, but for some, it is part of the freshmen days and they cherish the bonding which develops during such events with the seniors.

• Seniors at IIT are not cruel and do not impart it like a punishment. They have been through similar experiences and know how to work with freshers to turn them into their closest friends by the end of the academic session. 
• The student body can be approached if you feel offended in any manner, and they are quite helpful. 
• For my friend though, ragging was part of a social exercise which he cherishes.

You can also communicate your concerns with the seniors beforehand, I'd say you're fortunate to be part of IIT GN and the seniors are one of the best guides during that time for almost everything.
