Hi Ramu

Please specify the college or university of which you are talking about to take the admission so that we can help you in a better way. Is it Allahabad University or Andhra University?

Hope to hear from you soon. :)

The admission in Delhi University in B.Sc (Maths) program is done on the basis of 12th merit only and the cut off varies college wise. Also, there is no cut off declared yet for 2018 so to get a rough idea you can go through the below link -
