do i have appear for JEE2 to get into BIT for architecture
Yes, there are top 27 colleges which are accepting JEE score for admission in B.Arch. Programmes. So, BITS Mesra also takes the student on the basis of rank scored in JEE Mains. Also, only BITS Mesra offers architecture programme, while other two campuses i.e. Goa and Pilani do not offer it.
Yes.
You will have to appear in Jee Main paper 2 if you wish to get seat in B.Arch in BIT Mesra.
Good Luck!!!!
