Hi aspirant

You must be knowing form this year onwards all state engineering college will take admission on the basis of JEE mains marks .So NSIT,IIIT Delhi and DTU will take admission through JEE mains and there would be no JAC.

So to get admission in them you need to apply for state counselling only.

It depends on your All india rank,category rank,home state which college you will get.Use the college predictor to predict you colleges: https://engineering.careers360.com/jee-main-college-predictor
