Hey Aashi

I would suggest you to go directly for CA rather than waiting for your result and then do 3 years bachelor's degree.Because if you do CA with side B.com (https://b.com/) ,you can complete it within 5 years but if you do graduation from Delhi University you have to do 3 years graduation and then 3 years for article ship and then 2 stages more.So it will cost you almost 6-7 years.

So i would suggest you to do CA with side B.com (//B.com) .

I Hope This Helps

Best Of Luck!
