Hello Sumit,

I think it wil be very difficult for you to get into good NIT's through SC quota , since your rank is pretty less and the competetition is very high this time around. However You can get into NIT's like

NIT surat,

NIT Sikkim

NIT Goa

NIT Uttarakhand etc

Visit https://engineering.careers360.com/tags/list-of-nit-in-india?page=1 for more info on NIT's you can get for your rank.

All the best

Hope that helps
