okay yes agree with curveballs being a feature of life and something we should learn how to cope with BUT at the same time you said it yourself hahah it's not how the HSC works and I personally don't see it as fair to mess with the students like that after something they've prepared for for so long and are trying to do well in. What you said about it being a good idea throwing in questions students haven't seen before I completely disagree with though, because while maths is definitely about problem solving, I don't think its in anyway fair to throw in questions that the students haven't been prepared for and are way out of the students' capability - those students are in that class for a reason, and so should be tested accordingly. idk though just an opinion
