Hey there, 

As per your query I would like to tell you that according to previous year cuttoff marks you have chance to getting admission in main campus but it may be through the paid seat in main campus in bhu.. 

As per year the cuttoff marks varies depending upon the number of students appearing in the exam and the difficulty level of exam papers in the Exam. 

Hopefully it's will be useful to you. 

GOOD LUCK...
