Thank you very much.
I too don't like giving students guaranteed places in medicine only because they achieved high results in high school because I believe that achieving high results in high schools requires qualities that don't necessarily indicate someone's suitability as a doctor. The qualities are work ethic, memory, school, tutoring and luck.
The Monash structure doesn't really give any credit to ATAR. Biomedicine requires 90 ATAR, which is very achievable for anyone considering medicine. I think performing well in a competitive interview (I heard the UoM chancellor's interview is easy to pass) and being top 50 in terms of WAM, out of around 250 students, in my opinion, is a better indication that someone is suitable to become a doctor than performing well in high school (or even UMAT).
