Hello.

Architecture Aptitude Test(AAT) is for the students who qualify in JEE Adv and would like to take admission in B.Arch.Every year IIT Delhi conducts AAT.

I would to clear here one thing that admission in B.arch courses is not considered as per AAT rank, it is completely based on JEE Advance air but passing in AAT is mandatory for the candidate.

So aspirant concentrate on getting a descent rank in JEE Advance air.This rank also depends on the category you belong to,so as I can see u didn't provide your category.Reach out the following link to know the qualifying rank in Jee advance-
