I have got 13XX rank in CLAT 2024. I'm getting MNLU Nagpur as of now but I reckon I might get NUALS Kochi by the fourth list. My question is what can I expect out of vacancies? Which college can I get through vacancies with a rank like 13XX?

RGNUL or RML maybe. A slim chance of NLUO and MNLU too but I will advise you to stay in either NUALS or NLUO. Yes there's a personal bias and I feel NLUs like NLUO, NUALS, CNLU, TNNLU, DSNLU and GNLU Silvassa will grow at a positive pace in the upcoming years.
