Hello Tarun. You mentioned you have secured AIR 16800 in JEE Advanced but didn't mention anything about your caste. So, I assume you belong to General category.

Before answering your question, I'd like to inform you that If you want to pursue B.Arch from IITs, you need to, at first, clear JEE Advanced; next after the release of  JEE Advanced results, you need to register yourself for AAT (Architecture Aptitute Test), conducted by IIT Roorkee, successfully fetch a marks more than the cutoff prescribed and clear the exam.

Based on your Overall Rank in JEE Advanced 2021, you have successfully qualified JEE Advanced and thus you are eligible for registration for AAT. AAT is supposed to be conducted on October 18, 2021 for those who want to pursue B.Arch from one of the branches of IITs which offers the course.

As per your performance you may get admission at IIT Roorkee, IIT Varanasi and IIT Kharagpur for pursuing B.Arch.
