Can I get IIT Delhi with 4000 rank in JEE Advanced?

I am a 3rd year B.Tech student at IIT Delhi.

I assume you are an open category candidate. If this is the case, then you can’t expect to secure a top branch at IIT Delhi with 4000 rank. 

As per the cutoff 2023 for IIT Delhi, these are a few branches which had a closing rank > 4000 (for open category and gender-neutral seats)-

• Biotech and Biochemical Engineering- 5387 
• Civil Engineering- 4472
• Materials Engineering- 4055
• Textile Engineering- 6690 

But if you belong to a reserved category, or you are eligible for female-only seats, the situation will be better for you. 

You can check the official website of JoSAA- https://josaa.admissions.nic.in/applicant/SeatAllotmentResult/CurrentORCR.aspx to know the detailed JEE Advanced cutoff 2023 for B.Tech admissions at IIT Delhi. 

The previous year cutoff will give you an idea of the minimum required ranks for admission into the B.Tech programme at IIT Delhi.
