Hey Ritika.

Admission in Kirit P. Mehta School of Law, NMIMS for the course of BA LLB/ BBA LLB is done on the basis of your CLAT score only. Your LSAT score will not be considered for admission in this college for Law courses. Other than that you need to score a minimum aggregate of 50% marks atleast  in 12th boards for a fair chance of admission here. 

Best of luck
