It seems that gaining further insight into what each program entails would allow you to make an informed decision regarding the program that you should enrol in. While you are interested in both programs, there might be a possibility that you are interested in one option more than the other.
A Bachelor of Business/Commerce equips you with knowledge and skills that are relevant to the business world in one (or more) field of your choice. USyd's Bachelor of Commerce provides you with the opportunity to study one or more majors/minors, such as:
- Accounting
- Business Analytics
- Industrial Relations and Human Resource Management
- International Business
- Marketing
If you have completed Business Studies and/or Economics in year 12, you would have likely gained an idea of what the business world entails relative to the different business fields. Even if you have not taken either of the aforementioned subjects, you could reflect on whether you would rather pursue a career in business or a career in construction project management, i.e. which career fascinates you more. From what I can observe, it does not seem like the Bachelor of Construction Project Management offers a variety of options regarding majors/specialisations, as opposed to the Bachelor of Commerce.
Additionally, you may wish to consider your current/future mathematical ability when deciding which degree to study. In terms of the Bachelor of Commerce and depending on your major, you may be required to demonstrate sound mathematical capabilities (which is likely the case of the Accounting major), whereas in other majors (such as Industrial Relations and Human Resource Management), there will likely be little to no focus on mathematics. Instead, your analytical and writing capabilities are likely to be emphasised. I believe the Bachelor of Construction Project Management would not involve mathematics to a high degree, although there seemingly is some form of mathematics that underpins much of the work that happens in the construction industry which could relate to the following:
- Basic algebra
- Fractions and decimals
- Trigonometry
- Measurement and conversion
- Area and volume
- Ratio, proportions and scale
- Tolerance and error
- Cost calculations
I hope this helps!
