^ Thinking about it, that's definitely true. In my public school year 12 cohort (where there were only about 50 students) people weren't actually that distracting. It's like, all the people who weren't there to study left by the end of year 11. And then, even further, there were people who were very serious about their study. While the group of 'serious' kids at a private school might be looking at 95+ ATARs, in my class it was more that the 'serious' kids got 80+. But, I don't think the scores themselves matter that much, the fact that they are serious is what matters.
The internet helped me a lot in terms of navigating VCE, just to expose me to the kind of intellect out there, to the advice of past students, and to get people to take a look at practise essays. But, it helped me mostly to get an idea of how the system actually works so that I could exploit it as much as possible for my own ends. I think it meant that my expectations for year 12 were very realistic.
