Sir I got 81.07% in OBC can I get good nit?
The exact prediction would be tough for the qualifying marks as JEE Main is being conducted twice by NTA for the first time. Based on this score your probable rank will be 203,642 - 233,642 and your probable category rank range will be 66335 - 73835. You may be eligible for JEE Advance but the chances are less to a seat in NITs.
NOTE : Rank Predicted is on the basis of the expected total number of students i.e. 1152650 appearing in the JEE Mains April Session.
Good Luck!
