Hi Rashmi,

Thanks for asking careers360,

Look there is no as number to determine cut off foe NLU's as the cut off depends on many factors other than examination. There are 2100 seats in CLAT which includes the reserved ones as well. If you belong to general category you must have to score a rank  under 3000 to get sure about the national law school. 

This is  based on the previous years cutofffs. You must notice that is got a tie with any other aspirant then the marks in legal section will be preferable and after the gk section will be preferable. To get the rank of 3000 you have to score approximately 125+ marks out of 200.

Hope this helps you.

Good luck
