So on such rank and category you have no chance to get any of the NITs/IIITs/CFTIs and NEHU is a CFTI whereas NIT Agartala is NIT, so I would recommend you to either go for state counselling for state GFTIs or for private colleges or you can prepare for further attempts of JEE-Main and to help you in your preparation we have some resources which you can access from the link given below :-
