Considering that doing law is my target and being unsure of the results of CLAT 2024, is this backup even worth it? All other parameters constant, will it be fruitful to do so?

The only tier 1 NLUs with NRI quota are NUJS and GNLU. And maybe NLIU, if you considered it a tier-1. NLUJ recently stopped its NRI quota, it seems. None of these are the best NLUs, but NUJS and GNLU are pretty decent. But does NUJS even have space on campus to accommodate its increased batch size? If not, I’d suggest GNLU.

Yes, absolutely!

yes, provided that you dont have to take loans in order to pay for the seat
