Oh my lord, what is this obsession with getting a perfect score? Yes, a 99.95 would be amazing. You would feel brilliant about yourself - for a few months. Then uni would start, no one would ask about your ATAR, and it wouldn't be such a big deal anymore. What matters is getting into your course and knowing that you did the best you possibly could, and feeling that you actually learned something. Yes, the system is unfair for those who don't do a crazily scaled subject, but there are far worse problems with the education system than that. This is coming from someone who did a subject that rarely gets a single 50, as well as no maths/sciences/languages. The fact is, the root of the problem lies not in VCAA/scaling, but in what society places value upon. Because let's not forget, the GAT plays a major role in determining scaling. If society placed more value upon the arts, then people would take it more seriously, rather than just taking it as a bludge subject and bringing down the overall results, etc. etc.
TL;DNR: CHILL OUT GUYS, HIGH SCHOOL IS OVER. Enjoy your fantastic marks and unless you end up as some high up powerful person in the Education Department, the problems with the system are no longer something you have to think about.
