My 2 SAC rages:
Our new classrooms occupy 50 students but VCE English classes have only 25 students in each, so our teachers booked one half of the room, only to realise on SAC day that a year 7 class of 50 was timetabled in BOTH halves of the room. ==' so everyone was hallf furious and half happy.. what pissed me off, though, was that I was in the perfect mindset to do the SAC, but then boom.. postponed. I hate it when you get all ready for something and then it doesn't go to plan.
And another one about English SACs. I heard of this one class just cheating their whole way through the year, whilst their teacher was on their laptop. Typing up (generalised) essays in size 8 font, printing them and putting them into dictionaries, Googling plot summaries DURING a SAC on their phones, passing notes around, and yeah, you get the point. That annoyed the hell out of me the whole year, to be honest.
