With the score you're mentioning you'll get a rank somewhere between 480-1200. If you fall in general category then you have some chances of getting into CNLU Patna if you have the state domicile of Bihar as their closing rank lies somewhere near 1100.

Good luck, you have a pretty decent score and even if you don't get through don't worry because you have good chances in NLUs like NUSRL Ranchi and NLUJA Guwahati.
