    HSC Maths Exam Gets an F for Failing Our Students

    POV: kurt when he hears that his students cannot keep up *** On a serious note, it's not healthy to disregard stress. I don't believe that primary school students should have academic anxiety for anything at all - not for naplan, the selective test or anything in spite of what parents say...

    HSC Maths Exam Gets an F for Failing Our Students

    I think they should make ext 1 a 100 mark, 3-hour paper to address the concerns. There is no way you can test the scope of 12 topics effectively in 70 marks, or provide a range of easy to difficult questions, or sustain interesting and sophisticated questions with only 60 marks of short answer.

    HSC Maths Exam Gets an F for Failing Our Students

    I think students anticipate the last question too highly - or you could say that nesa puts in too little effort to make something sophisticated. In 4u, most people expect the very last question to be from one of the hardest sections of the syllabus e.g. reduction formulae, de movire's theorem...

    HSC ECO EXAM REACTIONS 2022

    I did the BOP one and it wasn't too bad. There's been lots of interesting developments in trade and artofsmart had made a video on it so 25 and 26 were comparable in difficulty (at least for me).

    HSC ECO EXAM REACTIONS 2022

    I imagine the marking notes for this year will comment that very few people did q28. I did anticipate that development would be an essay question, but I think the overwhelming majority (myself included) were attracted to the straightforwardness of inflation effects.

    HSC ECO EXAM REACTIONS 2022

    MC is probably the easiest since 2013. Short answer was a bit interesting in some places but not too obscure. And the essays were pretty much what you would expect if you saw what hadn't been tested in the past few years. Thank god they didn't pull a hard exam on us like what they did in maths.

    Economics Predictions

    Which one? I'm guessing it was the section 3 qs because q27 was free marks.

    Economics Predictions

    Hoping for macroeconomic policy, external stability or inflation/unemployment/eco growth.

    Is Rawmarks database reliable?

    Wait a second, aren't hsc marks determined from both raw external and moderated internal marks? So there isn't a one-to-one relationship between raw and hsc marks. That would account for the example above i.e. maybe the 49/70 aligning to 95 was the result of a very good internal mark obtained...

    Physics predictions?

    Interesting use of the word 'warned'. Compared to the rest of the syllabus, this is actually a pretty good deal for the long responses.

    4U & Advanced.... advice

    The topics you'll need for the extension levels of math are; Sequences and series Graphs and equations (curve sketching is eh, I don't think you'll need it neccessarily but it might help to know) Maximisation and minimisation All 2u integration -> possibly the most important thing u need to...

    Physics predictions?

    You would have to neglect the force of air resistance and friction... and gravity... and the constancy of time.

    Physics predictions?

    Assume the result is true. \Rightarrow E = mc^2 Multiplying both sides by a factor of 0 yields 0 = 0 which is evidently true Thus, the assumption is true

    y = ln f(x)

    It is not part of the further graphs topic set of transformations in ext 1, if that is what you meant.

    That ship sailed a long, long time ago... you should be saying that to the people here that worry about getting 'only 90' as their raw mark

    Mathematics Extension 1 HSC thoughts

    There really should be no formal complaint about unfairness. Some years are harder in some subject areas, some years it's easier. Maths was harder this year but we were also fortunate enough to get fair and easy english exams. As for other subjects I guess we'll wait and see. That being said, I...

    Nothing's worse than being proud of a question you thought you solved in a clever way... then u come to this thread and realised it was horribly wrong lol.

    Mathematics Extension 1 HSC thoughts

    Just another change to bring to your attention is that 6 is (C) because the projection onto that vector must have equal i and j components. Also, 8 is (A) by considering an isosceles triangle with unit length and requiring the joining side to have length to be less than 1, which can occur up to...

    Yep that's correct
