So do I have to look out for a 2017-2018 application? It says to write my UAC number when I haven't got my PIN yet.
I want to be absolutely sure that I don't fk this up...
I think you have to wait to be able to start your application
It's only June, and applications for tertiary courses for next year haven't even opened yet! In VIC, they only open in August, and I think from memory, it's something similar in NSW. Once you make your UAC account, and start the process of applications, then you can do your EAS application. But it definitely will be open until late in the year - from memory, last year for some categories you could still submit documentation in December!
All of the dates advertised on the UAC website at the moment are for applications for semester 2 2017 entry to university. So you just need to wait for a bit longer, until they start doing stuff for next years applications and offers
If you're still concerned, have a chat to your school's careers advisor, or send them an email. But definitely, don't worry yet. Hope this puts your mind at ease
EDIT: I just had a look - UAC applications for next year's admissions don't open until the 2nd of August, so you still have a few months before you can make your application.
