    Let your teacher know that schools no longer need to buy a subscription for RAP, it's available at no cost. It was announced to schools early last month.

    2023 ATAR/HSC Marks

    'P' appears to be incomplete as well. Unfortunately my scraping script is not working for the redesigned format. I am hoping someone else may have a complete list.

    2023 ATAR/HSC Marks

    Hi @carrotsss, I had a quick look and this appears to be missing the last ~1000 entries for family names starting with K? There may be other gaps, that is just the one I noticed.

    when do they release marking guidelines for 22 hsc exams?

    Multiple choice data is available to schools as soon as the results come out. It was (C) - individual identity. If it makes you feel any better, it was the hardest question with 46% of SOR2 students getting it correct. 41% chose (B).

    Is Rawmarks database reliable?

    What students should be supplying to the rawmarks database is the raw mark as well as the aligned exam mark - not the HSC mark.

    Is Rawmarks database reliable?

    Is it possible that student applied for illness/misadventure and the aligned exam mark was an estimate based on their assessment mark? It would explain the discrepancy.

    Advanced Maths Predictions

    I don't think there is a point to be made based on skew. Considering characters, there are 18 of them aged 14-15, and 15 of them aged 17-18. Considering actors, there are fewer at both ends (below 18 yrs, and above 26 yrs), and more in the middle.

    Advanced Maths Predictions

    I looked at the 3 sets of solutions posted for discrepancies, and also looked at mine. * Q15: I got 5/18 for 15a and 3/5 for 15b, which is different to two sets of solutions posted. I have verified both with 500,000 trials in a spreadsheet. * Q28c I agree with John Drake's answer: 2ln2-3/2+pi/4...

    Leaked DA Role

    No, the Distinguished Achiever List is based on Bands (Band 6 and E4), and Bands come from HSC marks - which is the average of the exam mark and assessment mark.

    Will our teachers know what we get in the HSC?

    I wrote that more than 11 years ago, and yes, it's changed! Those reports are still available, but NESA keep adding more useful analysis tools for schools. https://educationstandards.nsw.edu.au/wps/portal/nesa/11-12/hsc/results-certificates/results-services-schools/results-analysis-package-hsc...

    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...
