Thanks for your response! Well, from what I have gathered, there is no numerical GPA as you are just given a non-graded pass for the BDS annual examination component and a grade like pass, credit, distinction etc. for dental science and practice and the subjects are year-long. Last year I got a credit, not sure how that equates for a GPA but I'm assuming it is quite low

I will agree that passing dentistry alone is quite hard. I mean ucat is another thing, but when I sat UCAT in yr 12 i got 3050, which at the time was around 92nd percentile and I only practiced in the two/three week holiday before my test. Some people say that dentistry as a course is given more preference or something due to its difficulty so the GPA is more favourable, but I dont really think thats true at all. I am also not rural so I dont really have that going for me either. I hear a lot of ppl doing the jump or doing post-grad, but it sadly doesn't seem practically feasible. I have contemplated dropping out and just doing a regular biomed degree, but that seems really unwise idk.
Going by regular standards:
Pass = 4. Credit = 5. Distinction = 6. High distinction = 7.
From what i can gather, you'd need a bit more than 92% to be competitive these days unfortunately. You might have a buffer in AdeU given they want SA students though. If you put in a few months of study, you might be able to pull that up to the required %. Last years data can give you a hand with figuring that out. It's linked in my signature. From my knowledge, dentistry is given no advantage over any other degree. I wouldn't believe that otherwise you'd have people flocking to get in that way and decimating the dentistry course [simply put, dentistry is a very, very, very expensive course to run. They can't have people dropping into med left, right and centre.]
Before dropping out, weigh the pros and cons:
-If you drop out of dent, it's unfortuantely not a reparable action. You can't turn around and go back to it. Instead, you may be able to defer a year. CSU has a policy for 2 years no questions asked. Maybe AdeU has that option.
- Could you tolerate being a dentist? Or are you honed in on medicine? Dentistry will give you a quicker pathway to a fantastic and lucrative career that is hands on and cognitively challenging, but if med is you thing, so be it.
- What happens if you don't make it into med? What was your back up plan?
-Is it the stress of dental school overwhelming you? [understandable, it's overwhelming me too]
Given that dentistry is a dream couse for thousands of students, I would, as a generalisation, stay in it since most people are happy to do either med or dent. If, however, you're by no means keen on dent, I would highly suggest not dropping out into biomed. Pick anything but science.
As a final note, read the common pitfalls article in my signature too. It might answer some of you questions and remember, you can usually use almost any course to transfer into med be that law, psychology, nutrition, agriculture, physio, pharmacy, chemistry, heck, even wine-making.
Edit: University of Adelaide has a Maxillo facial surgey cohort and MaxFax hopefuls. If you can, if might be worthwhile tracking down student wants to study maxfax or doing maxfax. They need to have done med and dent to make it in and might be able to give you a hand with figuring out a good pathway.
