So I'm currently studying a bachelor of medical science at usyd...but I realised very early on that I had made the wrong choice and was just completely detached from my course - now I think I'll either just pass and get a credit in a few subjects (might even fail one). I want to transfer to arts (economics) in sem 2. Will a change in faculty reset my wam or should I just start economics at unsw in sem 2 so my wam will reset and this first semester will become a distant nightmare that exists only on my hecs debt?
