unwatchable. this kid shouldn't even be doing maths let alone 4u. jk jk but thats such a simple mistake how can you screw that up thats worse than my mistake.Just finished watching the video. My only criticism is at the very end he used a because symbol ∵ whereas he should have used a therefore symbol ∴
yeah i would say messing up algebra is underappreciated marks wise so maybe i get 5, i did have the intent to get the right answerunwatchable. this kid shouldn't even be doing maths let alone 4u. jk jk but thats such a simple mistake how can you screw that up thats worse than my mistake.
Matrix didn't put a dashed line for the straight line segment joining z=0 to z=-π. -1 mark.Matrix solutions: https://www.matrix.edu.au/2021-hsc-maths-ext-2-exam-paper-solutions/

Historically Terry Lee used to be the first with solutions up.
Recently he has been beaten by a few others.
Itute are very slow to put them up - maybe a month or so - some say they take a wiser approach than rushing to be the first.
Itute also seem to be consistently the most complete too - even putting them up for Standard 1 - which is very rare.
My criticism stands.unwatchable. this kid shouldn't even be doing maths let alone 4u. jk jk but thats such a simple mistake how can you screw that up thats worse than my mistake.
how does one even get chosen to do this.My criticism stands.
But I want to downplay it. It's not a great drama.
He went through quite a bit of hefty algebra and I'm glad he was the one doing it, not me.
Overall I think he did a great job.
I'm really confused at it. Let me see if latex works.
Almost...except you forgot the binomial coefficients.
I imagine that by scaling extension students up, it’s quite compacted at the top, so amongst the cohort with a scaled mark of 100 would be a range of raw marks, but anyone who achieves a raw mark of 100 deserves to be equal first. Students in different schools who achieve a perfect score in the exam shouldn’t be ranked based on school assessments, since assessments aren’t standardised. Congratulations on your awesome achievement!Correct I got 100 for x1 but i got nowhere close to a state rank.
