This is our post for discussion of the 2021 NHT Mathematical Methods exams (here and here). See also the accompanying 2021 NHT Specialist exams post, here. See also the relevant Witches: here, here and here.
EXAM 1 (Here)
Q2. (01/09/21) Asking for “the rule of y” in part (b) is gauche.
Q4. (01/09/21) A gratuitous and annoying framing in terms of matrices in Part (b).
Q5. (01/09/21) It is infantilising to provide the graph of the trig function.
Q7. Parts (a) and (b) have infinitely many correct answers.
Q9. A nice (if slightly misframed) question. (01/09/21) Commenters below have objected, probably correctly, to this question being on a Methods exam. The question is easy, at least with hindsight, but it is probably not the style (i.e. existence of) thinking expected in a Methods exam, particularly a Methods Exam 1.
EXAM 2 (Here)
MCQ5. There’s an issue if q is negative, but perhaps ok in context. Also, “equal to”, not “equivalent to”. (Yes, we’re the only ones who give a shit about this but it’s wrong, and we’ll keep saying it’s wrong.)
MCQ7 (22/09/21) The answer in the examination report is incorrectly given as C, instead of B. (08/10/22) Now corrected.
MCQ8. A screw up. There is no correct answer. See here.
(22/09/21) Of course there being no correct answer doesn’t stop VCAA from pretending otherwise. (08/10/22) The incorrect answer has now been deleted, with absolutely no indication that there is no correct answer. Unconscionable.
MCQ9. Bizarre and flawed. See here.
MCQ14. Improper integrals are not in the subject, but let’s not have that stop us pushing buttons.
MCQ20. Not wrong, just stupid.
Q2. Completely nuts. See here.
(22/09/21) As indicated here, part (d)(i) is utterly ridiculous and, consequently, the solution in the examination report is utterly ridiculous. (08/10/22) Uncorrected, of course.
Q5. Part 5(b) has infinitely many correct answers.
(22/09/21) The answer to Part (d) is incorrectly given as instead of . (08/10/22) Now corrected.
