This one, which has been discussed a bit here, comes from the 2023 NHT Methods Exam 2. It is a little strange. There are aspects of the question we like, or at least there are some interesting ideas underlying the question. Nonetheless there is no shortage of crap, and so here we are.

PoSWW 26: Elevated Concern
Yeah, it’s been a while. We’ve been busy. But, hopefully we’re now back with normal transmission, and we’ll start with an easy one, courtesy of Mysterious Michael. It is an exercise and solution from Cambridge Essentials Year 10/10A.
WitCH 76: Cos and Effect
Yeah, yeah, we should have done this one a week ago. Feel free to transcribe your comments from the Methods Exam 2 discussion post. You can also check out the discussion on stackexchange, courtesy of Stog the Stirrer.
WitCH 70: Troubled Relations
This is not an old one. It is from the 2019 Specialist Exam 2 and comes courtesy of student PURJ, who previously contributed to the discussion here. PURJ noted one, glaring, issue with the question below and its grading, but we think there are other issues as well. As with our previous WitCH, we’ll semi-update with excerpts from the examination report once people have had a chance to ponder and to comment.
WitCH 69: Sines of the Times
Yet another old one, from the 2010 Specialist Exam 2 (CAS). We’ll look to semi-update with excerpts from the examination report once people have had a chance to comment. (Readers are of course free to peek at the examination report, anytime they so wish.)
SOCK-IT-TO-YA
We had planned to not write about this one, dearly hoping it would quietly fade away. That was never going to happen, however, and, having made The Washington Post and the like, there’s now no purpose in not writing about it.
A few days ago, an American schoolteacher went through what was apparently her standard trigonometry routine, donning a fake Indian headdress and chanting SOHCAHTOA as a war dance, or whatever. Yes, the schoolteacher is from another era and, quite possibly, another planet. This year, however, a Native American kid in the class filmed her and then gave permission for the video to be posted on Instagram, where it appeared complete with a campaign speech, and school name and contacts. The snowball then did what snowballs do, the teacher has been suspended and so forth.
It is interesting times when a member of the Hitlerjugend is almost universally portrayed as the victim.
WitCH 51: Logging the Possibilities
The question below is from the second 2020 Methods exam (not online), discussed here. You may wish to brush up on your modal logic before attempting the question.
WitCH 49: Trigged Again
The question below is from the second 2020 Specialist exam (not online), and was flagged by commenter John Friend in the discussion here. John has spelled out the problems, but the question is bad enough to warrant its own post, and there’s arguably a little more to be said.
MitPY 9: Team Games
This MitPY is from commenter HollyBolly, who asked on the previous MitPY for some advice on diplomacy.*
Can you guys after all the serious business give me some advice for this situation: on a middle school Pythagoras and trig test, for a not very strong group of students. Questions are to be different from routine ones provided with the textbook subscription. I try “Verify that the triangle with sides (here: some triple, different from 3 4 5) is right, then find all its angles”. After reviewing, the question comes back: “Verify by drawing that a triangle with sides…”
How do you respond if that review has come from:
A. The HoD;
B. A teacher with more years at the school than me but equal in responsibilities in the maths department;
C. A teacher fresh from uni, in their20s.
Regards.
*) Yeah, yeah. We’ll stay right out of the discussion on this one.
WitCH 43: Period Piece
This one comes courtesy of a smart VCE student, the issue having been flagged to them by a fellow student. It is a multiple choice question from the 2009 Mathematical Methods, Exam 2; the Examination Report indicates, without comment, that the correct answer is D.
