3.OBC(NCL):-74.3166

4.SC:-54.0128

5.ST:-44.3345

so,if you fall under general category then you are not eligible ,else if you belong to any reserved categories then you are eligible for josaa counselling .

Hello Aspirant,

NTA has provided for the first time EWS reservation so it would be difficult to tell you the exact information about it but with this rank you might have the chance to get a seat in NITs, IIITs, GFTIs.

Good Luck!
