To get admission in NIT/GFTI, you will have to clear Jee Main paper 2 exam and when you get decent rank then you will have to attend the counseling and this way you can get admission there as this is the basic criteria to get entry in B.Arch program and apart from it, NATA exam is also there as many colleges/universities accept its score to fill seats in B.Arch course.

Good Luck!!!
