Hello Aspirant, If you got 92 percentile in JEE Main then your rank after JEE Main April will be around 80 to 85 thousand, Being a EWS Candidate you may get seat in low NIT's like NIT Srinagar, NIT Nagaland, NIT Utrakhand, NIT Manipur etc but also you will get branches like Production Engineering, Instrumentation and Control Engineering, Biotechnology etc,and for that also you have to wait for special Rounds. There is 2 special rounds of Counselling held if some seats remains vacant in first 7 General Rounds. In special round of Counselling very less students participate and chance of getting a seat in special round is high.But you should also apply in other colleges as there is not 100% surety that you will get  NIT's.
