The cut-off depends on your choice of course and college. It varies every year and it can be as high as 99% and as low as 40%.
To give you a rough idea of DU Cut off, you require at least 94% marks for admission to science subjects. For commerce stream courses like B.Com, you must have scored 94% in the top 4 subjects including a language.
On the other hand, the cut-off for Humanities subjects must be between 90-92%. If you are interested in doing Hindi (Hons) or Sanskrit (Hons), the cut-off is very low for these programs. You can easily get a seat at St.Stephens with 66% marks in Sanskrit (Hons).
For South Campus, you can reduce 2-3% from the ones mentioned above. Take a look at the previous year’s DU cut-off for better understanding.
