It's not that I'm against doing methods, I'm just worried I might not do well considering I'm not the best at maths and those doing it at my school are struggling. Just wondering, is the maths in commerce similar to methods?
The maths in commerce largely depends on what you major in. Regardless of major, there's going to be some maths though, as you'll have to do first year statistics (harder than further, but easier than methods).
If you major in Accounting = very little maths, though a lot of numbers.
Marketing = only some stats
Management = no maths
Business Law = no maths
HRM = no maths
but
Finance = some maths, but it depends on your units. Probably not a major to do if you really don't like maths, as some finance units are fairly quantitative, e.g. derivatives, and most will involve calculations (although often fairly easy).
Economics = a fair degree of unavoidable maths, including calculus
Econometrics = maths
Actuarial = difficult maths
which is why a 25 in Methods is required for Commerce. So, although you could theoretically get through a commerce degree without much maths by majoring in certain areas, a lot of the majors do require it. If you're really only interested in the non-quantitative side, then maybe consider just going with a Business degree. Business degrees are usually stronger on the first list of majors I mentioned and don't focus so much on the latter (though the degree structure is quite similar...one of the few differences is that Commerce means being required to choose a couple of units from a list of 4 other subjects, a couple of which involve some maths).
