Hello Aspirant,


You do not have to fill JEE mains paper 2 (B.arch) application form seperately.If you have filled JEE mains form then you can appear for B.Arch too.
Actually JEE mains conducts paper 1 (B.tech) and paper 2 (B.arch) examination at the same day.You will have to write Paper 1 (B.tech) first and at the same day you will have to write paper 2 (B.arch).
You can clear your doubt further from the link below :
