what you guys reckon a raw of 70-75 will align to?

Really hoping its like 90-94

ik bro...really getting nervous about the cutoff, bur realistically i reckon it will be about 75 tho...hopefully im wrong

I can't say. I know that for proving the irrationality of the nth root of 2, the proof of fermat's last theorem does in fact require some elementary irrationality results (including this very thing) so it would be circular reasoning. This would need the consultation of an expert in algebraic number theory to resolve.

If I remember correctly, the proof of Fermat's Last Theorem does utilise some mod p results which would almost certainly satisfy.

no its probably going to be like in the high 80s.

88. I'd be happy with that, thats equivalent scaled to me getting like 94 in chem, take that any day tbh

Where’s @idkkdi I think we need to know what he thinks of the exam lol.

oopsies

i don't think the test was that bad, main thing was that 2020 was just too easy in comparison, so people got baited.

compared to the old syllabus tests with the busted alignment, I don't think the test was that bad.

but who knows, maybe everyone getting baited makes alignment pog.

honestly feel this, it just cause the 2020 paper was literally free marks until just q16

Here's most of the paper

So by most of the paper you mean that part of Q13a was in the answer booklet, so we can't actually answer the question without that bit? Have you got that bit? Without it complete solutions to the paper will be impossible.

Once again the race is on to see who will be the first to come out with complete solutions. But this time the whole race is futile.

Without that bit nobody can finish it.

its like a unit circle with 16 lines around and a+ib being on the 3rd from real axis and just above the unit circle for memory

OK. This might be completely wrong but I made this from your description. Is it about right or completely wrong?

EDIT: Apparently is was more like 20 lines. See post #345 at https://community.boredofstudies.org/threads/maths-ext-2-predictions-thoughts.397709/post-7406520 for better picture.

Just the prediction I was hoping for lmao. I think I did moderately well. I reckon alignment would be quite nice this year as the general consensus from what I’ve heard so far is a lot of silly mistakes and half answered questions.

Interesting observation, they used "arctan" in the paper rather than the usual inverse tan notation. I think that's the first time I've ever seen a HSC paper use that notation...

that graph is a monstrosity

i was pleasantly surprised

fr it had me questioning if what i was doing was correct smh

doesnt include real and imaginary as a line so should be one extra past a+ib and one going negative tanx like for memory

did we need to use arctanx to get full marks i just used inverse tan (tan^-1 x)

full marks?
I'm getting a solid 1 maybe.


this is the graph btw

oh thought you were talking about the mechanics question but yeah i got something (similar but drawn completely terrible)
