Arash, maths is not the most important subject for a commerce student.  Though it gives the added benefit of doing Bcom Hons from great colleges but Bcom pass is equally a good course for the students. So if you want the admission in the college the foremost thing is having a good percentage. If you have scored nicely you can get admission in any renowned college of your choice be it Kirorimal or Ramjas. You should score atleast a minimum of 96% in your 12th board to get admission in DU colleges.

Several of my friends had commerce without maths and they got admission in good colleges.

You can easily pursue another course with your bcom degree like CA, CS, actuarial science etc. It is not important to limit yourself to just Bcom pass.

Focus on the main subjects like Accountancy, English, Economics and Business studies. Make these subjects as your strong points. If you are able to score above 95% in these then you can easily get admission in any renowned college.

All the best for your studies and do well.
