I'm getting 132.75 in my clat 2019 Can I hope getting admission in GNLU?

Absolutely YES, provided you still fall under the eligibility criteria (age).

One can give his/her best shot to get selected in top law schools ( rankings- NLSIU or NALSAR…) even after they've got admitted into National Law University Jodhpur-NLUJ or Gujarat National Law University-GNLU

I. Since you'd be giving CLAT 2019,…

1. if you are lucky enough and your hard work prevails…you can get your desired top-notch law schools as per rankings. I am sure you understand that you've to discontinue your first year at NLUJ or GNLU to get admission into top law school, i.e you have to under go a year drop or year waste in your career persuasion.
2. If you get alloted into law school which is even under rankings to your previous qualified one, i hope you'll stick to the one you are already in(NLUJ/GNLU). You'll already be in your second year for the CLAT2019.

In First list NLU(O)... there are apt chances that u will get NLU Guj in 2nd list

Sure to get NLU Odisha in First list. In the Second list it might get upgraded to GNLU.
