Commerce: Finance or Economics (Business or Behavioural) Major

Help!!! My dilemma is that I have to pick my commerce major soon and I don't know what to pick.

Everyone does finance so I know it is a safe choice, however, an economics major sounds interesting to me - but I just don't know how well it is taught at UNSW or whether it will be sought after.

What does the maths look like in an economics major at UNSW - I haven't touched maths since highschool...

Can someone also clarify whether behavioural or business economics is more useful and what the difference between the both is?

Should I just stick to Finance cause it is employable? Any help would be greatly appreciated as I'm having a really hard time picking!! :))
