Sir my clat score is 63.75 which college I have chance to get admissionfrom obc category

With 63.75 marks, your predicted rank is 13k-15k in the general merit list. Your marks aren't qualifiable to get into any NLU in the 1st cutoff but there are chances of getting through by the next ones. But keeping in mind the difficulty level of this year's paper and that this prediction is solely based on previous years' trends, the cutoff trend might see a change and you might get admission in the 1st round itself.
