You could in the future though. I mean if I hadn't gotten the ATAR I needed I would have done a different course and somehow found a way into the course I actually wanted to do. In the end you will get where you want to be.
if you dont fit the requirements dont even bother for EAS! haha
sending a letter to the uni would be a last-ditch measure
the time for doing STAT and UMAT has already passed this year, i think your best bet is with that aptitude test (which name i forgot). its basically an IQ test- if you do well in it they'll give you more consideration.
yes. to gain more consideration do an apititude test (STAT or UMAT or some other one i forgot its name), apply for misadventure/disadvantage appeal, apply for EAS and send them a letter telling your age
im sorry but i have no idea what a BA is like. what i most recommend, know what i do, is for you to repeat another year to gain a better a work ethic and study skills + ATAR. uni has a far larger workload than high school, and you WILL get kicked out if you fail a few times. i dont know how much work is in a BA, so do some research on that
dont believe what that guy says about HECs fees: you'll pay it off in the years that you've 'saved'.
