Hello,

If your brother wants to study BArch at NIT (any campus) then he have to appear JEE Mains Paper2. If you secures a good rank i.e. below 2-3K then he can surely join at any campus. If you are saying that he can join through some YOJNA then no its not possible. YOJNA is made to ease the process that doesn't mean candidates don't have to follow the process. He has to do everything which is mandartory for a candidate to do for admission. On the basis of qualification your brother can apply for  any yojna, reimbruisement or scholarships. That is different thing.

NOTE:- He has to follow the complete process as states by NTA board and further counselling process.

Hope it helps!
