Congratulations! If your SC rank is 1,300, then you can definitely get admission in some of the NLUs, but the only catch is that you will get admission through the state quota, so if you have the domicile of the respective states in which the following NLUs are located, then you may easily get through them according to the past year's cut-offs.

MNLU Nagpur: 11603 (opening), 31798 (closing)

MLNU Aurangabad: 15447 (opening), 36653 (closing)

NLUJAA Guwahati: 14578 (opening), 46516 (closing)

Hope I have answered your question. All the best!
