I guess all we know for sure about their selection criteria is that everyone who gets to the interview stage has a fair shot at securing an offer (assuming they meet the subject prerequisites and academic hurdle). Last year, the cut-off to receive an interview was 83rd percentile. However, based on MSO data, someone on 83rd and two people on 84th percentile ended up getting a final offer.I thought that it was a 40/40/20 percent thing where ucat was interview decider and then it is 40% weighting for atar and interview and then 20% for ucat. Then the highest scoring from that weighting will be the places chosen.
Actually now that I think about it, that is probably how med is done and dentistry is done differently.
I did chem, phys, 2u (accelerated), 3u and 4u maths if that helps during year 12. Not sure what's up.did you/ are you doing at least 2 sciences (which can include maths) in year 12? it could just be an error, but not satisfying the prerequisites would explain why you're getting that message
