Based on the trend from the previous year, I can estimate that your score will be in the 37–42 area. Since you have not specified your category, I will assume that you are a student in the general group. I'm afraid to say that your prospects of being admitted to well-known government universities like NITs are almost nonexistent based on patterns and cutoffs from prior years' colleges like NITs and IITs.
