UAI of 90, an incredible UMAT score, and awesome BSing skills may just get you a place at the University of Adelaide's Dental School.
Melbourne and Queensland have their cutoffs at OP 1/TER 99-whatever, or something. It's huge, but if you're lucky enough, you may get a scholarship and a couple of return flights to whence ye came from.
If you don't do Chemistry, don't (bother) apply(ing) for Melbourne.
In Sydney, there's University of Sydney's grad. dent. program, which requires a pass average, a GAMSAT score over 50 in each section, and a MMI (a series of eight one-to-one interviews with a two minute break between each; you get asked to assess a scenario, which is written on the card, and to offer your thoughts). There's no requirement as to course or subjects in both uni or secondary school.
"As for the criteria for ‘Good’, however, the candidate shows a degree of originality and creativity in their answer. There is evidence of the ability to generalize the subject content to areas not covered in the formal scenario. This may include bringing in their own previous experiences. There is strong evidence of reasoning and problem solving both on the professionalism of themselves and that of others. There are strategies for how they themselves and others might behave in the given circumstances. The answers appear authentic."
That's an "Excellent"-class answer.
Station X:
(standard question)
Why do you want to be a physician? Discuss this question with the interviewer.
Station Y:
Circumcision (ethical decision making)
The Australian Pediatric Association has recommended that circumcisions not be routinely performed. They base this recommendation on their determination that the benefits have not been shown to clearly outweigh the risks and costs. Doctors have no obligation to refer for, or provide, a circumcision, but many do, even when they are clearly not medically necessary. Medicare no longer pays for unnecessary circumcisions.
Consider the ethical problems that exist in this case. Discuss these issues with the interviewer.
