increase the difficulty of our exams to at least either up the anti on the content we're learning or make more difficult questions available as practice questions.

i agree but nesa would think its unreasonable. hsc questions are a breed of its own kind. they're meant to look unseen and unlike any question you've done before. if youve seen every type of hard question they could ask, then whats the point of the hsc exam. that's not to say people haven't seen these questions before, probably some dr du kids or something since they miraculously get 100 in every exam. also writing questions with the dexterity of hsc level is hard and requires a team of exam writers which nesa probably wont do just for practice qs

Three points of data (2020-2022) does not imply a trend though. I mean in the past we kept talking about how NESA kept writing boring generic HSC maths exams (with only a handful of interesting challenging content) and now here we are…

that is true. But the level of complexity this test, was surely on par, if not even higher than the 2020 and 2021 papers. needless to say 4u was a huge leap. Just hope alignment is better!

no question these tests are harder. 3u last year was pretty simple. just comparing the multiple-choice, there's no question this year was harder. last year's mc was straightforward. The same goes for 4u.
something to think about is that with the start of a new English syllabus, questions are known to get made gradually harder by exam writing teams as the years go on and more resources and essay questions become available. moreso, the markers also demand higher-quality responses but that's an English thing. trebla is right in saying the end of old syllabus questions were uncreative so perhaps the opposite of english is eventually true for maths. time will tell.

There really should be no formal complaint about unfairness. Some years are harder in some subject areas, some years it's easier. Maths was harder this year but we were also fortunate enough to get fair and easy english exams. As for other subjects I guess we'll wait and see.

That being said, I am PRAYING that they do not pull a challenge on us for the sciences. NESA had their evil fun with math, so hopefully physics is simple enough this time around.

Y’know, I could’ve lived my life not knowing that I lost the easiest marks on the paper doing +2y on my calculator by accident.

Ignorance is bliss

I am expecting a state rank from you sir

i would assume physics is going to be harder this year. last year was easy and boring af.

That ship sailed a long, long time ago... you should be saying that to the people here that worry about getting 'only 90' as their raw mark

‘only 90’ isn't going to get me my state rank … quite literally going to get a higher raw in e2 than e1 at this point

i’m actually fuming, i’m pretty sure I got 15/15 in Q14 but I made way too many tiny errors across the paper in the easy questions

 

[tgone]

TL 14a is incorrect:


their substitution for (0,1) is done incorrectly, C should equal -2ln2.

Also, 14b has an incorrect conclusion (correct method however)
14d can remove ambiguity from choosing which solution by solving the quadratic eq (1) on the pdf w.r.t sqrt(n) rather than squaring both sides.

 

[tgone]

Looks like Terry Lee has fixed up 14a. This is why I think it is better to have a link for his solutions rather than a copy of the file here.

Yesterday's pdf was timestamped 26 Oct 2022 at 6:19 pm

The new version (same link) is 27 Oct 2022 at 4:59 am: http://advancedmathematics.com.au/Resources/2022 Ext1.pdf

Not sure about the other bits though.

Yep, I messaged him, looks like he fixed it.

 

[tgone]

I made the same mistake so how many marks could I potentially lose for that?

You would only lose one mark for that, you’ll get a carry through for the final answer being slightly off.

Does anyone know if nesa is lenient in the way they award marks for working? Like does it always have to be a substantial amount of relevant working, or making an attempt at a question is enough? Thanks

 

[notme123]

i had same concerns last year for 3u as well. they mark based on criteria which I'm sure you've seen in marking guidelines before. if the attempt you made had something relevant they may give a mark but depends on how many marks are allocated for the question. they might give more marks for 4 markers than a 2 marker.

I know im late to the party but personally i found the exam to be pretty good besides 14 c and d
