Our double degree in medicine allows school leavers who have achieved exceptional results to study medicine by undertaking a three-year undergraduate science degree followed by the four-year Doctor of Medicine (MD).
UNSW doesn't seem to have a specific ATAR requirement like USyd does, although the 2021 lowest ATAR was 97.2. You should definitely be aiming for the highest possible ATAR as medicine is considered highly competitive (irrespective of the university). Similarly, you should be aiming for the highest UCAT percentile (again UNSW doesn't seem to explicitly state a specific UCAT score). Once you can ensure these two requirements are met, the only thing left you'll need to worry about is your interview performance, which is also important to receive an offer.
