hii Shubhalee ,
According to last year cut off of BHU PET programm , you have very less chance to get admission in main campus , but you must be wait for 2nd or 3rd round counciling . But the chance of admission is very less . You can apply for some other university like DU and state university for M.A. history .
For information regarding admission - https://www.google.com/url?sa=t&source=web&rct=j&url=http://bhuonline.in/&ved=2ahUKEwiwlOCNk_3iAhVVaCsKHUUADzIQFjAAegQIBxAD&usg=AOvVaw18wXL8CGIXxONTCOcwkNe
