Hey there 

As per your query I would like to tell you that according to your rank and based upon the previous year cuttoff marks you cannot get admission in bsc maths honrs through regular seat at main campus. 

Due to less number of seat available in courses

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 and the number of students appearing in the exam  

HOPEFULLY it's will be useful to you  

GOOD LUCK
