Hello Bhavya Guruvu 

Jee advanced eligibilty is not decided by paper 2.

For getting into architecture courses in IITs then you must clear JEE mains both the paper and also clear Jee advanced by scoring the qualifying marks of your category and then you will be eligible to appear for AAT and then getting a good rank there will land you to IIT roorkee and IIT kharagpur.

and Eligibilty in JEE Advanced is decided by the score of your paper 1 marks.

Hope that helps
