Hey!
I also go to one of the most disadvantaged schools (info in spoiler)
Spoiler
-At the start of the year we were given a talk about expectations as last year only a third of students got an ATAR above 50
-In the past few years our overall duxes have had below 90 ATARs
-someone duxing a subject with a study score in the 20s isn't rare
-it's rare for any student to have commercial notes, guides etc. and I don't know of anyone in my year level getting tutoring
-low SES area, many students are first in family to consider uni, often problems at home etc.
I get what you mean. I really do. This has affected my VCE in quite a few ways from subject selection (dropping subjects due to timetable clashes, not having spec offered at all etc.) to the culture.
For me personally, I look at my methods result of 34 and find it very dissapointing. (For context at a MAV lecture the presenter suggested I might be a 45+ type of student) There were three of us at the top of the class and the person who got rank one gave up on VCE at the end of the year and sat their exams without doing any prep. I couldn't help but wonder if this would've happened at a different school. But in the end, I could've/should've done better in the SACs and thus escaped a GA1 of C+. (Not to mention that the other 2 GAs were entirely under my control and carry the heaviest weighting or the fact that I had a great teacher who did a great job giving me exam advice and prep even if my highest GA was only an A).
Yeah, it can suck sometimes and you can wonder "what if" but in the end each student's learning is their responsibility and they need to own their performance. SEAS provides recognition of challenges that can affect learning but the ATAR itself needs to remain a measure of performance - and not be school adjusted.
From a technical standpoint looking at your GAs it would seem that your exam performance is what brought you down and that other students in your cohort had better exam seasons than you. As PF said, your cohort has no impact on your exam results.
I got a 49 in written comm on the GAT and only a 38 for English Language - I know that 38 is a more accurate reflection of my quality of work in that subject. I only scored in the 30s on the GAT for math/science yet I scored in the 40s for physics, chem, bio, and psych - I know that again my study scores are a more accurate reflection of my performance in these respective areas.
GAT scores are interesting, but they are certainly not a perfect predictors and I wouldn't use them as a basis for challenging results.
If you don't trust me because of my math/science affiliation, know that I have a friend at my school whose only subjects from this sector were methods and further, they didn't study a language, and they scored in the 90s.
The system is certainly not perfect but it is the best one that we have and it has been designed by people with more expertise than us students. It wouldn't really be fair if being average in a very competitive cohort got you the same mark as being average in a relatively weaker cohort. That's what scaling is designed for. Why you pick the subjects that make you compete with future med students who were very focused and determined if the difficulty of this wasn't compensated by scaling?
To end on a brighter note, going to an under rep school can be a great thing because you learn a fair amount of self sufficiency which is a very useful skill to have.
I'm very much looking forward to Uni where we won't be competing against students who have hundreds (or thousands) spent in VCE help, where I can learn more, collaborate more, and grow more. Things get better and I hope you share in my realistic optimism.
