    Is Samuel Davis Incompetent?

    Something else to consider ... when NESA updated the syllabus for 2012, Sam Davis was the only SDD textbook author (as far as I know) to update his book to reflect the new syllabus. There is not a big market for SDD textbooks, so it showed a commitment to SDD students and teachers to do this...

    HSC Standard Mathematics Predictions / Thoughts

    I had slightly different answers. In part (a) use the graph to find the x values corresponding with A=30000. They are x=100 and x=200. x=200 is the larger of them. Part (b) the largest value for A occurs at the vertex of the graph. This is half way between x=100 and x=200, i.e. x=150. Substitute...

    HSC Standard Mathematics Predictions / Thoughts

    I don't think so. There was a simpler answer I read on facebook that a teacher posted there. Split the triangle OAB down the middle. You can then use right-angled trig to find the height of that triangle. (tan 18 = 4/x) This gives you x=12.3107... You then find the area of triangle OAB as 1/2...

    HSC Standard Mathematics Predictions / Thoughts

    I did exactly the same as you, and also had difficulty getting there with the PV table. I think in all the discussion about the crickets and the decagon that the complexity of this question has been lost a bit. A teacher at my school came up with the following method, which is slightly...

    Your raw mark was in the low 40s, around 42 or 43. That gap between your exam mark and assessment mark is very large. I would suggest getting a clerical recheck.

    That was the plan but the new format of the list broke my script. Sorry everyone.

    Scaling when you're the only person in your class?

    It doesn't apply to English Extension 2 because there is no exam, but for other subjects you need to consider what happens if you're in a class of 1 and you have to apply for illness/misadventure for the HSC exam. I think you get your school assessment mark as your exam mark (and hence moderated...

    raw marks

    Sorry, but neither of these are true. The way the marks are aligned depends on the Performance Band Descriptors for each course. A team of judges, who are drawn from the HSC marking team for each subject, determine what raw mark on the exam paper corresponds with the borderline of each of the...
