2) Now, for people looking to take the B.Arch/B.Planning UG degree course at IIT Roorkee or IIT Kharagpur Have to PASS the AAT (Architecture Aptitude Test) exam. Note : Only those candidates who qualify for JEE Advanced and secure an ALL INDIA RANK in it and put IIT Roorkee and / or IIT Kharagpur as their choices for B.Arch course in the online choice filling form are eligible to give the AAT exam.
