Hey, you can also apply to: Monash, University of Western Australia, University of Adelaide, Bond University, James Cook University, Uni of Tasmania.
ISAT is an easier test with a simillar format to the STAT test, it's based on mathematical logic and logic. I know how umat works for an international student, anything over 75%-85% should get you into a few medical schools(depending on the international student cohort) as most have Int-FEE(International full-fee) places. But I unfortunately know little about ISAT, i'll ask around. I thought some uni's accepted UMAT or either ISAT.
Auckland and Otago is a complicated way of getting into medicine, best to stick out of it's way. You must do a B. Biomedical Health Science for one year and then do umat. Then try to get into medicine as a 2nd year student.
