Which are the NITs I may get admission?

Getting into a college which aligns to your personal objectives is necessary. Majority of government institutions don't have good infrastructural facility. and moreover, these days getting into a reputed private institutions has become very difficult. You should not focus only merely getting into NI

It all depends on the cut-off marks allotted by cbse board.I think the cutoff will be around 115.BTW you have secured very good percentage in your boards,so if you do not get a seat in nit's then go for some well reputed deemed university.
