Hello dear

Although nothing can be predicted exactly as EWS category has been introduced this year, but according to me there is negligible chance for you to get any seat in any of the NITs or IIITs. Even if you get one, that would be the lowest branches in the lowest ranked colleges. Either, you should consider private universities as an option. There you can get admission on the basis of mains rank. Or else, you may get a seat through the CSAB round. You should refer to the college predictor once- https://engineering.careers360.com/jee-main-college-predictor

I hope this helps. All the best!!
