This is completely off the track question. You have Given JEE mains and you want to join nit , then how in the world are you talking about sports. 

There is no such category in nit's. You will get admission completely based on your JEE mains score and 12th percentage >75% . 

So you better study hard and get above 99 Percentile and get a seat in nit Warangal next year. 

All the best.

Thank you
