With this percentile in JEE Main, your All India Rank will be around 160000. With this rank, you have negligible chances of getting a seat in NIT Warangal. However, if you go to Special round counselling and if home state quota applies for you, then you may get a seat in " Bio-Technology " branch at NIT Warangal. You have some chances of getting Bio-Technology branch from other state quota also, if you go for Special round counselling.

You should fill up mre choices during JoSAA counselling so that you may get a seat if not in NIT warangal then at least in some other Institute. As something is better than Nothing .

Hope it helps.
