Hi Chinmay,

First of all I want to mention that for getting into B.Arch into any of the IITs you have to qualify JEE Advance along with AAT Exam.

Now, coming on to the preferred IIT in B.Arch stream I would probably rate IIT KHARAGPUR first, then IIT Roorkee and finally IIT BHU based on their placements and on their respective NIRF 2020 Rankings.

I hope that you have now got a fair idea of the colleges, but at the same time you also have to work very hard for getting into these IITs. Wish you all the best for your Preparations!!
