No that's fine. I appreciate your help. Can I ask why I am unlikely to get into medicine? I am also very interested in Dentistry and there is less completion for specialisation once qualified. Would I be more likely to get into Dentistr? I want to do something with my hand that challengers me more but does not kill me getting into.
Thank you all so much for your help and advice. It's much appreciated.
Dentistry is certainly 'easier' overall to get into if you were applying through the undergraduate pathway as UMAT and/or ATAR (or in your case GPA) requirements are lower on average.
There are very few graduate entry only dental programs in the country (as far as I know it's just USyd and UniMelb) for which certainly the competition is intense and it is arguably harder to gain entry to these than to gain entry to a graduate entry medical degree at a different uni (i.e. it's still easier to get in, by the numbers, to dentistry at USyd or UniMelb than to medicine at USyd and UniMelb - but its pretty damn close).
In your position I would certainly heed
@LMG!'s advice strongly - any study you undertake now should be useful to you in and of itself rather than solely as a way to get marks for medicine. The numbers quoted are close to the actual standard however if you only limit yourself to one or two schools (which someone with your tertiary record necessarily must) then you'll find that your chances of getting into that are lower still - not only are you competing for fewer places by limiting the number that you can apply to, but because those are more accommodating to applicants, there are necessarily a higher number that qualify to those schools (further diluting your chances out).
You essentially then would be using the GAMSAT to compete against another 14000 people or so (as a rough estimate as there are a good proportion of people who have sat the GAMSAT the year prior and scores are valid for 2 years) for these ~300 places available to you. Simply by the numbers, it's reasonable to say that the odds are rather stacked heavily against you. This isn't necessarily a reflection on you personally, but any applicant in your position, which is why
@LMG! has suggested to open up the possibility of undergraduate medical schools for your application - I would certainly be applying to every medical school I could in your position, and more than half of the places available to someone in your position are in the undergraduate system - i.e. you hypothetically double your chances by applying through both pathways.
Certainly at this point in your life you may wish to reconsider whether it would be feasible to undergo medical training. If you are 36 now, you'll be 37 next year when you sit the UMAT and GAMSAT (definitely sit both!) and 38 if you gain entry. You'll then be 42 in your final year (assuming a 4 year degree), 43 in your intern year, and then, assuming you pursue General Practice in PGY2 and pass everything first time, a new GP at 46. If you pursue other specialties the training is longer by variable numbers of years (you are almost certainly too old to feasibly pursue neurosurgery or ophthalmology, for example). If you wish to pursue medicine, you should be aware of this; if you know that you will not pursue General Practice (and instead go for a longer training pathway), you may wish to reconsider medicine as a career entirely as it may very well be an unacceptable training requirement in terms of number of years.
None of this is reassuring, but you should certainly know what you are attempting to put yourself through should you succeed; additionally, in the more likely scenario, you certainly want to be getting the most out of your investment (no matter what kind of study it is and no matter what stage of life you are at).
Going by this, unless you are into doing degrees for interest only, if you pursue study, you should either be pursuing it in an area that will advance your current career (e.g. that will help your specialisation in podiatry) or in an area that will allow you to reskill into a different career pathway (such as doing a nursing degree and then using that to become a nurse). Medicine is likely quite an inaccessible path for you; you are of course welcome to try, just ensure that you don't invest time and money for nothing.
