Hey.
The cut off for admission in any of the NLUS for the general category candidates ended around a rank of 1600.
Considering your score your chances don't seem much in any of the NLUs.
You can go for private colleges accepting CLAT scores for admission instead.
There are various Private Colleges that accept CLAT scores other than the National Law Universities. Here is a list of a few of them.

Jindal Global Law School, Sonepat
Kirit P. Mehta School of Law, Mumbai
NIRMA UNIVERSITY, Ahmedabad
ICFAI Law School, HyderabadSchool of Law, GITAM University, Visakhapatnam
Alliance School of Law, Bangalore
IFIM Law College, Bangalore
LLOYD Law College,Greater Noida
Amity University, U.P.
Asian Law College, Noida
Manipal University, Jaipur
