my older sister is a HSC marker, and she marks business studies this year.
this is what she tells me, some HSC markers who've been at the venue for hours and hours will mark really hard, which is understandable because its boring, reading and reading the stupid shit over and over again.
they do have 3 markers marking the same paper, but chances are, they are all just as bored and pissed of, so they'll just skim it and pretend theyve remarked the thing, when indeed they;re thinking about something else
u might be lucky and be one of the first papers to get marked.
so its all in the hands of luck. my sister last year sometimes read the first page out of 4 (essay), and gives a mark based on that. cuz after reading well over a few thousand pages of shit, no one wants to read anymore.
as for short answers, well they;re just gonna look for keywords and if u got it, u get the mark. they arnt gonna read it word for word. come on.
