Your marks are deducted when the percentage calculated against the cut off released by DU because you are from Science background and didn't study any subject of B.Com. If you belong to general category, your chances are very low to get admit in this course. If you belong to the ST category, maybe you can get admission. But don't lose hope and wait till the last cutoff to come. You can check out last year's cutoff released by DU on their website.

Yes, there is a chance. Can't really say. Keep up the hopes and look for the cutffs.
