Hello Aspirant,

See cut-offs are bound to change every year depending upon various factors such as the number of candidates appearing in an examination, the number of candidates qualifying an examination, difficulty level of the paper, and so on.

If we go through previous year's trends for cut-offs of DU then it shows that not only for B.Sc. Hons in Mathematics but for all courses have been increasing with significant figure and if you want to enroll yourself for B.Sc Hons in Mathematics in DU then you have to aim your score in class 12th around 92% at least if you belongs to General Category otherwise 89-90%.

You can also check out previous year's cut-off trends from the link given below :-

I hope this information helps you.

Good Luck!!
