Hello Aspirant,

See according to previous year's cut-offs you have almost no chances in any of the NITs on such rank for Architecture course because closing rank for NITs was around 700-750 for OBC candidates. So you have very less or almost no chances for any of the NITs but yes you can go for some private colleges that offer Architecture course on the basis of class 12th score or on the basis of low score in JEE-Main like SRM University, Dehradun Institute of Technology and likewise

You can check out previous year's cut-offs from the official website of JOSAA as given below :-

Or else I would recommend you to either go for preparation of 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 :-

Note that the above prediction is made on the basis of latest cut-offs available on official website of JOSAA or CSAB and the cut-offs are bound to change every year depending upon various factors such as the number of candidates appearing in an examination, the number of candidates qualifying an examination, difficulty level of the paper, and so on.

To have a list of all those colleges which you can get based upon your marks, category, and state you can use JEE-Main Architecture College Predictor:-
