Dear Harshit, JEE Main Paper 2 opens the door to NITs and GFTIs offering B.Arch course whereas admission in colleges like SPA Delhi and CEPT University Ahmedabad is offered through NATA.

If we look at the two exams, National Aptitude Test in Architecture (NATA) is an specialized test meant to test the aptitude of candidates specifically for studying architecture.

JEE Main Paper 2 is developed in such as to check the aptitude of prospective students in drawing, mathematics and basic aptitude of student.
