Yeah you really gotta pop off in the interview, it basically makes or breaks your application and UCAT, especially being only 20%, can only do so much. That said, if you set your sights a little bit lower to a later round offer, it's much more achieveable as Adelaide is one of the unis that bear the brunt of declines, particularly first-round ones by interstate applicants who get a better offer within their own state in the same round.I should make a correction here^, not just for Boi2369 but for general info.
True for UNSW, with 99.95 + 99th an average interview is more than enough in my estimation.
But not so for Adelaide because of 3 factors different to UNSW:
1) UNSW's offer ratio is 1 in 3 (top third overall), Adelaide's is like 1 in 5 (top 20% overall)
2) Adelaide weights UCAT only half of interview i.e. the interview has more potential to overcome a top UCAT
3) SATAC boosts so many applicants to 99.95, diluting the "power" of a raw 99.95
That was why myself I got UNSW+Monash but failed Adelaide haha.
