^ yep that's pretty much it.
or undergrad MBBS is sometimes 6 years (ex. UNSW)
usually, people have an idea of what they want to do before they begin, and it hardly ever stays the same by the end of a degree haha. a common one i've heard of, is people wanting to be surgeons, ending up GP's.
don't go into med thinking your wanting to do this, as it will probs change, you do rotate around a lot of specialities so you'll find one you most like. who knows, you may still want to be the same.
edit, yeah odd the link isn't working hmmm.
i've done a ridiculous amount of research on all unis, and i'm applying for UQ provisional entry & UNSW as interstate undergrad uni's only, none of the others i'm too keen on. so search around, some may take your fancy, others won't.
