You secured a seat at NUSRL, wow, Good news, Congratulations! You got it on the basis of your performance in CLAT 2018 whcih needed some dedicated preparation because around 40000 candidates compete for available 2400 (approx) seats. Faculty, Infrastracture and Students play an important role in building the image of an institute. NLUs are no different. In your case, whether it's a good or bad institute only you and your performatnce and dedication towards study and learning ropes will decide that. They are offering you a seat assuming that you got the required rank and score on the basis of your aptitude. Now, you have to prove that you are really worthy candidate and that your success in CLAT isn't fluke. I hope it helps!
Yes I think it's worth it. Umm talking about future aspects, yes I think it will obviously grow stronger and better butI think it will take long long time to be among the elite law schools
