I'm nearing the end of year 12 and about to start year 13. For the last 3 years, everything I've done with regards to work experience, shadowing, and subject choice (Maths, Physics, Biology, Chemistry) has been with the intention of studying medicine at university.
After doing more research though, I've become really interested in business and finance. What should I do in order to maximise my chances of getting into a university course of this field at this point and time, other than tailoring my personal statement to this field? (Bachelor of commerce, finance major; the only prerequisite is mathematics)
Take online courses by harvard, mit, etc. about the subject? (i.e. edX) Work experience/shadowing? Gap years to take the a level? is it too late?
Investment banking stands out to me, but this could very well change.
