Hello dear aspirant,

Hope you’re doing well..

In University of delhi Colleges , best of four percentage is not taken into consideration for B.Sc. (honours) courses.

To take admission in B.sc. honours courses, the applicant need to calculate PCM or PCM aggregate and then see if they meet the cut off set by colleges.

In your case, that is in case of B.sc honours maths, you need to calculate the aggregate of PCM.

Hope this clears your doubt.
please ask if you have any more questions

All the best for your future!!
