You're not the only one Nick, I don't know either :oops:
This is like terribly nerdy... so here goes! (I'm turning into coblin)...
Odette, you do further. VCAA's Study Scores are normally distributed with a mean (average) of 30, and a standard deviation of 7.
If you use a calculator, the probability of getting above 40 is approximately 10%.
In most subjects, the chance of getting an A+ is also 10%.
So, we can similarly conclude that 10% of people get A+ and get 40.
Consequently, as the cut-off for a BM A+ is dropping 11 marks, hence dropping 11 marks almost assures you of a 40.
Unfortunately, VTAC rectifies that absurd situation though by immediately kicking you in the groin, saying "LOL!!!" a couple of times, kicking you in the groin again and then scaling you down three points for good measure.
This only affects about 51% of the BM population, however. The other 49% simply get scaled down three points.
