Thanks for the welcome
So just to make sure, there isn't much I can do in between accepting a offer and finishing VCE? Been spending my last few days in Australia feeling anxious that I should be doing something during the time in between the two even though I don't know what I could be doing. All I know is that the courses I've applied for doesn't state that an interview is required which is a godsend seeing as how I won't be able too in the first place
Don't need to get stressed out, I had the same feeling when waiting for my offer too and I was in Singapore the entire time after receiving my ATAR till I received my offer
As jamonwindeyer pointed out, you can accept your offer and enroll your subjects online. Orientation week and information day is totally optional, even though highly recommended. I missed mine back then and it was totally fine, as on information day usually they just go through the subjects available for the major and how to enroll; which can be done easily as all the information and instructions are all online.
If you're afraid you're missing out anything, just see a student adviser when you return, they'll fill in the gaps for you.
As for the holidays, definitely get plenty of rest and have lots of fun, and to get prepared I'd recommend checking out the course information, start collecting resources, such as prescribed textbooks or online tutorials, and familiarizing the materials ahead. Getting prepared and learning ahead will go a long way to make the transition to uni life a lot smoother, and not to mention soothe your anxiety
