How do I fill the online anti-ragging affidavit considering it is asking for the number of students in a batch in IIT Dhanbad?

My brother also filed an online anti-ragging affidavit recently. He too was confused because he was asked to fill the batch size although he hadn’t even started attending the classes. He randomly wrote 60 only to realize later that it was just a formality. Students need to focus on other details while filling out this form like their email ID, your name, your father's name, Institute to which they are getting admitted. Once you fill in all these details correctly you will receive a mail consisting of 4 pdf files namely:

1. Anti-ragging undertaking by the student.
2. Anti-ragging undertaking by parent/guardian.
3. Summary of UGC regulations
4. Summary of the judgment of the Hon. Supreme Court.

All you need is the anti-aging undertaking of your parent or guardian and yours. Get this typed on a non-judicial stamp paper and then get it attested by a notary and submit it to the college.
