To get admission in NITs is it necessary to qualify JEE main?

ADmission in IITs and NITs is based on one’s performance in JEE Mains and Jee advanced......one needs to do well in JEE mains and if the score falls under the calculated cutoff of IITs, then during counselling rounds one gets a seat in IIT and for NITs one has to qualify JEE advanced........Now you can clearly make out where exactly do you stand....I can suggest you some leading institutions where you can seek admission.......Kalyani Govt. Engg College, Nadia….…....Loknayak Jaiprakash Inst of Tech, Chhapra,..............Lovely Professional University, Phagwara,............BIT Sindri Dhanbad
