Hi,

At 85 percentile in jee mains and obc ncl you can get some of the north-eastern nits with home state quota and gfti colleges as well.

Based upon the percentile that you have scored you have better chances of admission in private colleges rather than NITs. It would had been better if you had mentioned your home state, there are seperate home state ranks for admission to NITs.

you can predict the colleges for you using the jee mains colege predictor at https://engineering.careers360.com/jee-main-college-predictor

All the best !
