Difficulty of mathematics in B. Comm?

How difficult is the maths involved in a Bachelor of Commerce? I'm concerned that my lack of 2-unit maths knowledge may really hurt me throughout my degree (B. Comm majoring in finance and banking). Is this a reasonable concern? I'm anxious as to whether i'll be able to get through subjects like BUSS1020 (Quantitive business analysis) or others within my finance major.

I'm currently undertaking a bridging course for 2u maths (to somewhat learn/familiarise myself with calculus and such) however I really don't have a good grasp on the concepts. So I feel I may be spending a lot of time in the MLC throughout my degree.

Any advice is greatly appreciated, thank you very much.
