Can I get into CNLU with 89.25marks in CLAT and OBC certificate of Bihar????ans plz

With the score you're mentioning you'll get a rank somewhere between  4400-5600. If you fall in OBC category then chances are a little less that even with your state domicile you'll get CNLU Patna. But you may get NLUs like Trichy, Shimla, Ranchi and Jabalpur

Apart from that you have some chances of getting into VIPS and Nirma University also.
