Hello Aspirant,

If we go through closing SC ranks of last year then it clearly shows that closing SC ranks were around 300-380 and your SC rank is even beyond 400 so you have very less chances of getting into any of the NITs .

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

Or you can check out the following article :-

JEE Main Paper 2 Cutoff 2021 (B.Arch and B.Planning) - Opening and Closing Rank (careers360.com)

So on such category rank you have to go 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 :-

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 College Predictor:-
