so if you get under 99.95 = UMAT + interview
if you get 99.95 = interview only
USYD doesnt use UMAT at all.
The combined med is an science or arts or music degree first and then the med one (so you don't start med until fourth year)
And you basically just get 99.95 and ace an interview to get in haha
Otherwise, just do a different undergrad course and apply for post grad med (which you have to sit GAMSAT for - UMAT but crazier, i tell you :O)
This path is the same number of years, you just don't have the guaranteed med spot.
For all the other unis (UNSW, UWS etc), UMAT is super-important and it's not just a personality test; it's logic and problem solving etc
GOOD LUCK
