No , it is not compulsory to stay in hostel for nit Bhopal student . There are many localiities studying in that college but staying in hostel saves time it create studying atmosphere and you can take part in weekly activities.
Talking about MANIT , Bhopal at present approximately 2000 students reside in Institute. It is good Institute as compared to other Institutes around it.
It is not compulsory to live in hostels for students in NIT Bhopal . You can stay outside the college . But if you stay outside NIT Bhopal you cannot participate in the weekly activities conducted in the college . The facilities provided in the hostel are very good and you also have a Wi-fi provided in the college .
Hope this helps you.
