A Scaffold for Nothing

It’s been fun VCE times down here in Victoria, but reportedly there have also been issues up north. While our students have been lamenting their inability to calculate the area of a 20 x 20 square (Murdoch, paywalled), New South Wales’ HSC students have been struggling with projectiles subject to air resistance. Same same. Continue reading “A Scaffold for Nothing”

How the Other Maths Lives

A few days ago, the Sydney Morning Herald had an article on “the hardest question” from this year’s NSW Extension 2 Exam. The question is worth 5 marks, which equates to 9 minutes of a 3 hour exam (accessible here). The question, and another question (6-ish minutes), which apparently came along for the ride, are posted below. Readers’ homework exercise is to Compare and Contrast.

Don’t Go West, Young Man

No, Burkard’s and my new book has nothing to do with going West. A signed copy of our book is, however, first prize in our new Spot the Exam Error(s) Competition. (Some information on our previous exam competition can be found here.)

We spend a fair amount of our blog time hammering Victoria’s school curriculum authority and their silly exams. Earlier this year, a colleague indicated that there were perhaps similar issues out West. We then had a long email exchange with the semi-anonymous Charlie, who pointed out many issues with the 2017 West Australian Mathematics Applications Exam. (Here is part 1 and part 2. WA’s Applications corresponds to Victoria’s Further Mathematics.)

Following our discussion with Charlie, we sent a short but strong letter to WA’s School Curriculum Standards Authority, criticising one specific question and suggesting our (and some others’) general concerns. Their polite fobbing off indicated that our comments regarding the particular question “will be looked into”. Generally on the exam, they responded: “Feedback from teachers and candidates indicates the examination was well received and that the examination was fair, valid and based on the syllabus.” The reader can make of that what they will.

The Competition

Determine the errors, ambiguities and sillinesses in the 2017 WA Applications Exam, Part 1 and Part 2(Here, also, is the Summary Exam Report. Unfortunately, and ridiculously, the full report and the grading scheme are not made public, and so cannot be part of the competition.)

Post any identified issues in the comments below (anonymously, if you wish). You may post more than once, particularly on different questions, but please don’t edit on the run with post updates and comments to your own posts. You may (politely) comment on and seek to clarify others’ comments.

This post will be updated below, as the issues (or lack thereof) with particular questions are sorted out.

The Rules

  • Entry is of course free (though you could always donate to Tenderfeet).
  • First prize, a signed copy of A Dingo Ate My Math Book, goes to the person who makes the most original and most valuable contributions.
  • Consolation prizes of Burkard’s QED will be awarded as deemed appropriate.
  • Rushed and self-appended contributions will be marked down!
  • This is obviously subjective as all Hell, and Marty’s decision will be final.
  • Charlie, Paul, Burkard, Anthony, Joseph, David and other fellow travellers are ineligible to enter.
  • Employees of SCSA are eligible to enter, since there’s no indication they have any chance of winning.
  • All correspondence will be entered into.

Good Luck!


Well that worked well. Congratulations to Number 8, who wins by default. Details are here. We’ll attempt another competition, of hopefully broader interest, in the near future.
