Well, the answer to this question depends on your choice of discipline and score in the entrance exam. If you secured a good rank in the JCECE exam and a bit low rank in JEE Mains then it is recommended to opt for your favorite branch in BIT Sindri. If you are getting the same branch in NIT Raipur then placement figures will definitely fluctuate.
Infrastructure:
Talking about infrastructure, NIT Raipur is way better than BIT Sindri. Though the campus is BIT Sindri is large but the buildings, as well as the hostels, require a lot of renovation.
Type of Institute:
