To get a study score of 1 in Specialist Maths you need to get 0/120.
Getting 1/120 actually boosts your study score to around 5-7, soooooooo
Mate if you just guess C for all the M.C You'll get a study score of 10+, guaranteed! XD
4517 kids doing Spesh, and 106 kids didn't rock up to the exam. So that means the worst kid in the state would be ranked 107th, placing them in the bottom 2.369% (100/4517*107).
VCAA says on their website that they use a mean of 30, standard deviation of 7 when calculating study scores. Using these parameters, if we take the integral from -infinity to 15.5 of such a normal distribution (i.e. a study score of 15, since VCAA rounds to the nearest integer) and times it by 100 to get a percentage, we get about 1.9%.
WHICH MEANS that as long as you rock up to the Spesh exams, shade in the bubbles and leave, you're GUARANTEED at least a study score of 15, if not 16. Which scales up to 24.2, according to VTAC's scaling report (it says the mean SCALED score for spesh is 40.6 and the standard deviation for SCALED scores is 8.3; plug these into the normal distribution and integrating from -infinity to 24.2 gets you approximately 2.4%. The kid is ranked 2.369%)
MORAL OF THE STORY? If you're someone planning on doing five subjects for VCE, why not pick up Spesh in Year 10 or 11? All you have to do is rock up to the exam and you'll get a guaranteed boost of 2.4 to your aggregate. Also, if you're a Year 12 failing Spesh, there is hope! hahahaha
Wolfram Alpha syntax for this is: 100 * definite integral from -infinity to 15.5 e^(-((x-30)/7)^2/2)/(7sqrt(2*pi)) if anyone is interested lol
