Hello,
If you want to pursue B.Com in any top college like Delhi University or St. Xaviers College then you must have Mathematics as a subject in class 12th in commerce. We cannot predict the safe side, you should work hard and try to get as much marks as possible. In Delhi University the cut off for getting admission in top colleges like Shri Ram College of Commerce is 99% and above, so you can think accordingly. Study so hard that you can get at least 95 in 12th board if you wish to get admission in any top college in India. Having mathematics will also help you in future when you will appear in entrance exams for Masters.
I hope this helps.
