I think something weird happens in this case. When there are twoo few students, I SUSPECT that the actual exam score of the top student in the state determines that student's study score - so if the student gets 100% in the exam, that student is assigned a 50. Which explains why in Latin, when a similar number of students sit the exam every year, one year the highest score is 47, another its 44, another its 49, another its 50.
That's what I was getting at.
In popular subjects (eg Further) you can get a 50 without perfect scores (due to the number of participating students) whereas in Latin you need a perfect score to get a 50.
We could well have a situation where the VCAA set a very difficult Further exam where nobody gets a perfect score and yet many students will get a SS of 50 and yet a Latin student with a similarly imperfect exam gets a 47.
It's no big deal, just saying...
