If It follows previous years trends then Its Impossible to Get NIT. You could be hardly able to end up in any government college. More than 180 Marks required to get into NITs. Even at this marks No one can assure you whether You are going to clear JEE Mains or Not.

Never target for such low marks there is no benefits of appearing in JEE Main if you target at this range. Try for at least 200 Marks in JEE Main to get NIT.

It depends on the cut off of that year . According even if you get any nit it would not be helpful for you because it would be just like tag for you . Because for better nit's you have to score much better than this. You have to desire high so that you can score high sorry if my words hurts you in anyway bt as a student you should always be expecting higher
