I know this is a late post, probably irrelevant at this moment. To give some context I am currently in yr 12 but completed a 3/4 subject last year. Throughout the year I'd been putting a lot of effort into my studying, and getting decent sac marks, around 90% (which I was pretty happy with in a strong cohort) and I ended up with a study score of 50. So I was pretty surprised. I paid to get my exam marks back from vcaa to be hit with a shock: I'd lost 21 marks (out of a 120 mark exam). That's around 83%, worse than most of my practice exam marks. Anyway, I now feel as though I don't deserve such a score? People say how 50 students know their stuff backwards but with losing 21 marks, how could this possibility equal a study score of 50? Does anyone have a similar experience?

I thought I should edit this post in case anyone else is reading it. It turns out it was a misunderstanding and I actually interpreted the results wrong, but I only realised this recently when I looked over my exam scores from last year. It was 21 marks lost out of the 240, not 120, as the exam is double marked. In other words one assessor took ten marks off and the other took eleven marks, for a grand total of 219/240 ~ 91%
So for this particular year, a 50 in bio was equal to dropping 10-11 marks. Hope this clears up any confusion
