Is there any option available in delhi university through which we can convert regular B.COM(H) into a correspondence course after 2 yrs.?

I passed 12th(commerce) this year with 95% in best 4 . I want to do b.com (h) from a good DU college (regular) . Actually i am planning to do ca as well. I will give cpt this month. But since ca requires articleship training , I wont be able to continue with a regular course. Please help.
