Hello aspirate 

Seeing last year trends cut off for RMLNLU, Lucknow we can expect cut off around 110-115 marks for obc candidates this year. As last year 112.75 marks was the cutoff and 118.5 in 2017 .Since you also the home domicile you can easily get this institute with 112.5 marks. 

It may be possible you won't get in first round but till last round you'll definitely get it. 

Thanks
