The admission in my college is purely on the basis of JEE Mains(through which you get NITs and other govt. funded institutions) in JK Institute of Applied Physics and Technology .
Usually, the cutoff is not very high and ranges from AIR 12000 to even up to AIR 35000. Also, there is one employee quota which I guess exists in every college and approx 10-12 students take admissions from that quota.
