hiii Sanchayeeta ,

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 have chance of getting affiliated college . You can apply for some other university like DU and state university for M.A. hindi.
