I think in general, we all aren't allowed to see exactly the amount of EAS points we would actually get when applying. We only can have a really close guess as to how much we will get, because it depends on all the factors/ questions that they asks you and how much you've actually put INTO the EAS form and how your circumstance/s would have either have an adv/dis advantage in gaining points or not at all.
It all depends on how good your application is...
But yeah, in terms of.. like, WHEN they'll actually ADD it on.. I THINK they just add it on a few days/weeks before the round offers are released (Main round.. final round etc), BUT I think they disclose EAS points to the public because they don't want people to find loopholes or "hack" their way into gaining points for other future HSC students/ HSC'ers.
Though you could just call uac and they'll probably tell you, but I doubt they'll tell you.
All in all, you could actually kind of estimate how much you'll get anyways... use google and your research on the EAS guide/instructions and you should be able to find out how much you'd prob get.
