I reckon there’ll be more algebraic proof questions

we bouta get an imo inequality in q16

I’m pretty sure IMO inequalities aren’t as common in IMO anymore cuz of the possibility of bashing them out (idk it’s not like I’d know how to solve them)

In all seriousness, inequalities ain’t even that bad like 95% of the time. Anything vectors related usually makes me wanna kms (excluding ruse 2022)

yea tru we more likely to get some complex bashing geometry question but if the exam markers are lazy they could totally just steal an inequality off aops lol

Is the 2020 hsc easy in comparison with the others ? Caus thats the only one ive done

 

[Dontcallmedude]

Heyo u guys tried the 2024 north Sydney girls paper? It's so wierd lol. Some very 'interesting' proofs, questions requiring worded responses, weirdly very easy but thought provoking stuff scattered around with some interesting methods required to solving questions. Wierd af paper ngl

Yeah it’s easier have a look at the 2022 paper thats abt as hard as it’s been so far imo

how on earth are we supposed to do some inequality proofs
genuinely some of them you just have to pull the method out of your ass
is it worth memorising them? like im legit contemplating it at this point

also are we allowed to use am/gm for greater than 2 without proof (unless the question specifically asks to prove it)
because ive seen trials where am/gm for 3/4 is allowed to be used without proof
is this the case for hsc?

No, we cannot quote it. Most of the proofs will be requiring you to prove it for those 3/4 cases. You must also prove the basic case. However, you can reference it in a later question if you need to.

Yep. Its the easiest by a considerable margin
