Hi aspirant since you have 78.5 percentile in general EWS category so most probably your rank will be in range of 150K-200K and I'm sorry to say you that on this rank it is not possible for you to get into NIT with this rank in my ipinion you must go for GFTI's an d you may get any one of them on behalf of your rank.
