hii Pankaj , 

As you mention your rank here you have very less chance to get main campus of BHU . But you will wait for 2nd and 3rd round counciling for further updates . 

You can check further updates - bhuonline.in

You can check expected cut off -- https://www.google.com/url?sa=t&source=web&rct=j&url=https://university.careers360.com/articles/bhu-pet-cut-off/amp&ved=2ahUKEwiJwY7Yz_DiAhVFv48KHWF-CsoQFjADegQIAxAB&usg=AOvVaw3Fws9cf1mNJwzCL5XX4XwZ&ampcf=1

Hope I resolved your query.
