Hey Akansha,

BCom Hons requires you to have maths in 10+2 as well. So if you took BCom Hons then you could expect that you are going to study maths so better focus on your weakness you will improve for sure. Hons requires maths skill but if you try to focus on improving maths it won't bother you a lot. So better try to overcome your weakness. 

Best of luck

Dear student, most of the universities in India do not allow as candidate without maths as a subject in class 12 to pursue BCom honours. A student who does not have maths can only go for BCom program course. It is so because BCom Honours is more indulged in maths rather than BCom prog.
