I got 82.23 percentile in jan 2019 mains will there be a chances for getting admission in nits and top 10 engineering clgs in telangana

You didn't mentioned your category here, if you belong to SC/ST then surely you'll get admission in top NITs with this percentile but for a general category student this would be difficult as to get admission into NITS you need a percentile more than 97%. Moreover if you want to get admission in top colleges of Telangana you can also get them by scoring good in EAMCAT and if you're a domicile if Telangana then the cutoffs would be favorable for you.
Thank you.
Hope it helps.
