Hello Anurag

This is not a very good score.

This marks range between 90-120 there are many students so you rank may fluctuate a lot.

But you may get rank around 40-50 thousand ( or may even more than this). With this rank you may get admission in nit Patna but you have to compromise with branch.

You can see last year cut offs and have a reference about it:

Good luck.
