I found accounting, especially in the earlier years at uni, quite challenging and difficult to get good marks in (i.e. passes and bare credits). Contrasting this I did significantly better in finance subjects, and even economics with HDs. Somehow I ended up becoming quite good at accounting though
Have never touched economics at all until first year. I did macro and another economics unit last semester. At first I struggled a little for the first 2 months. At that point of time Economics is really a strange field for me. But it gets pretty interesting as time passes. Turns out it wasn't that bad after all, managed to resurrect macro from a C to a high D and meanwhile screw a little on another economics unit, placing it 3 marks away from HD. This semester I'm doing micro, same approach (but less struggle), and I hope this unit gets resurrected too. Future plans? To do more higher level economics or not, it all depends whether do I need to resurrect these units again and again.
Accounting, .. quite easy all the way till first year's financial accounting unit . As this is my first year second semester, I'm now taking year 2's corporate accounting. Mmm.. quite a struggle to be honest because the workload and level of understanding between these 2 units have a large gap. It's understandable on how things work (well, except for tax) and a lot to memorise (referring to preparing accounting layouts). This Wednesday I'll be sitting for Corporate Accounting exam, which would be the last exam. Taking this unit (corporate accounting) definitely eliminates everyone's mindset that.. it's not just all about book keeping when Accounting standards start to creep in, resulting more people giving up financial accounting major.
Finance, I can't give any comment about that yet. Going to take it next year. And as everyone says, if you fail/can't cope with an introductory finance unit, you'll most probably have to ditch that as a major. Hopefully that doesn't happen to me.
