Hope I have solved your query. Do upvote if you are satisfied with the answer.

Yes, you can look for colleges under Annamalai and Bharathiar University. They offer courses with less fee and a large number of seats will be always there.

Sorry, no chance in IIIT Delhi with this rank. Your CBSE score is good but, your JEE rank is not good for admission if you want CSE.

Registration for Architecture Aptitude Test commences after the announcement of IIT-JEE Advanced results. Eligibility Criteria for AAT Only the applicants who successfully qualified JEE Advanced can appear for AAT to get admission to B.Arch. Hence you are not allowed for AAT examination because you did not write JEE Advanced.
