Hello Sapna, No, unfortunately, you won't be able to get a seat in RMLNLU, Lucknow. 2018 closing rank marks of the last admitted SC student was around 116 marks. You might try for some private colleges that accept CLAT Marks. There are some colleges like UPES, ICFAI law college that accept CLAT score.

Hi Sapna, 

Considering your marks,  previous year cut offs and the level of paper,  You may secure rank in the range of 1500-2000 (Category Rank) you have a decent chance of making it to RMLNLU since you will get the advantage of Domicile. Keep an eye on the vacant seats also in case you don't get RMLNLU in counseling round.
