Hello aspirant!!

LNMIIT is a good college but it is not compared to any NIT (at least not nit Patna and Raipur)

Now in NIT Patna vs Raipur

Taking that you are getting car in both institutes it's better to take in nit Raipur as location of nit matters a lot to our behaviour as well as our personality

And Raipur>>>Patna in that way

Also in terms of infrastructure Patna is a good one

But placements wise nit Raipur car has 7.50 LPA average and which is far better than nit Patna and also here good companies as of Amazon ,Samsung ,Nokia comes.

Hope this was helpful.
