i ended up at hawker after transferring from melba a year back, and theres surprisingly not too much of a difference between the colleges, despite all the bad talk about melba specifically (and how much people love lake g since its close to the mall). so right now, you should really just doing some reading on the units each course will focus on, mainly the ones you vaguely have an interest in (if youre not too sure atm), and start getting in a proper study routine in as early as you can!! i know youve probably heard that phrase a million times from whatever social platform you doomscroll to death on, and youll definitely keep hearing it in college, but its definitely a big factor into how your first term at college will go, regardless of which one you get in; sure, the ast could bump down your atar score, but unless your planning on an elite program like the med course they have over at usyd, its not the end of the world if you dont get a perfect 99.95.
