Hello Uday!

Your JEE advanced marks doesnt help you to get into a National institute of technology. It would help you to get into an IIT.

You must have qualified JEE mains, so your rank that you secured in JEE mains will get you into a NIT.

So please tell us your category rank in JEE mains.

you cant guess

1..understand that this percentile is only in one session of paper , this was not in total candidate's

2. Now , 2nd paper of jee main will be April so The student s who scored less percentile have a final chance to get more and improve there score

As the rank will be calculated by taking your best score

Let assume you not improved your score then your rank will definitely goes down as other will improve their percentile viceversa

From this percentile you cant calculate your final rank , so this implies that you cant decide nit and branch.
