I'm confused as to how to access the alias account once it's set up. I can log into my zmail account, but I haven't received the email I sent to my alias account to check whether it was working :s
USyd are also known for purely considering WAM if it's good enough- I have a friend who recently transferred into Law who had an ATAR of around 90, but had quite a high HD average. It's still possible, but incredibly difficult. Be prepared to put in some solid effort!
