look i did hsc in 2023 and 2024, you can trust me or not. the difficulty isn't massively different, but yes this year i personally found easier, probably because i was more prepared and it was slightly easier. however it wasn't easy straight up, some things were very conceptual. in the end we can never know for sure but 50/70 would be very high IMO, i think it'll be 47, could be 48, but would be surprised if it was any higher

any set of points in x-y plane has an inverse because you can reflect any set of points about the line y=x. the result doesn't have to be a function.

so question 14b was wrong

 

[H.S. Carslaw]

So why is the question wrong?

 

[tywebb]

well here is the question



to which we find in nesa's marking guidelines the answer [-1,1] which is the correct answer to the wrong question.

so if we assume the answer is correct then the question is wrong

 

[H.S. Carslaw]

So are they going to remark it?

 

[tywebb]

dunno

i also dunno what they said about it at the nesa presentation on hsc marking at uts last week

hopefully they clarify this in the recordings of it, but that doesn't seem to have come out yet.

it is possible a remark may not be necessary

i think it strange though they give marks for [-1,1] which is wrong, given that the actual correct answer is

it would be interesting to know how many marks they give if a student just said
