Hello Innovative girl, 

                   CLAT 2019 was considered easier compared to previous year i. e., CLAT2018. Which means that this year cutoff will certainly go high.

          As compared to last years cutoff rank for RMNLU you must have a min. rank within 800 even for obc category to get into RMNLU.

           With your marks in CLAT2019 is seems difficult or almost impossible to have a rank under 1000 thus there are almost no chances to get into RMNLU with these marks.Rest you may register for counselling and see what best can happen.

GOOD LUCK
