Hello,
.
No,not every course needs maths.
And compulsory subjects will be differ from college to college.
.
As you have mentioned you wanted to do commerce courses.
B.com
Bachelor of economics
BBA
BMS
BBS
BBM
.
These are some of the value commerce courses.
.
When coming to B.Com Hons needs maths and it varies from college to college like in SET maths is compulsory and in BHU it's optional.
.
In the same way even BMS varies from college to college
.
Where as BBM AND BBS doesn't need maths.
.
Hope this helped in clarifying your question.
Thank you

It is mandatory in b.com hons only.
