No, appearing for JEE Mains or National Aptitude Test in Architecture (NATA) is mandatory for admission to the Bachelor of Architecture (B.Arch) program at Chandigarh University.

The Council of Architecture (COA) is the apex body in India for regulating architectural education. They mandate that all students seeking admission to B.Arch programs must qualify in an aptitude test like JEE Main Paper 2 (B.Arch) or NATA.

Chandigarh University adheres to these COA regulations. Their website mentions that candidates must qualify in either of these exams for B.Arch admission.
