Hello Aspirant,

Since you have not mentioned your category so considering it as General.

So on such CRL rank in JEE-Main you have good chances to get top NITs with CSE/IT branch but on such JEE-Advance 2021 AIR you have very low or almost no chances to get CSE in any of the IITs because closing AIR for IITs with CSE were around 2k. But note that you can definitely go for some other branches in IITs on such AIR.

If we go through previous year's data of seat allotment then on the basis of CRL mentioned in the question by you, you can go for the enlisted colleges :-

Motilal Nehru National Institute of Technology Allahabad - Computer Science Engineering (3073)

National Institute of Technology Calicut - Computer Science and Engineering (3682)

National Institute of Technology Rourkela - Computer Science and Engineering (3296)

Visvesvaraya National Institute of Technology, Nagpur - Computer Science and Engineering (4708)

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