One of my friends is in his last year and hasn’t experienced anything related to ragging. Although there might be some fun interaction with the seniors but no extremities that hurt.
Here are some insights of NIT Calicut in the context of ragging.
Dress code ragging
Physical abuse
Academic performance
My friend has done assignments and called his seniors sir but nothing more than that. Nobody is forced to do anything if somebody does then he will be subjected to strict punishments as mentioned above. Even the assignment thing doesn’t last for long as there have been many instances where teachers could identify the handwriting and many students have been caught in this act. So, you can relax as there are no chances for extreme ragging or bullying of any kind.
