Hey Khushi
The cut off for admission in RMLNLU Lucknow in the previous year for the State Women General was a rank of 650.  Considering your rank, your chances  for admission in this college along with Domicile does not seem much. The cut off for admission in any of the NLU last year closed at the rank of 1600 for the general category in the previous year. Hence with a rank of  4913 your chances for NLU seem less.
