this is so sad

is there a list of all the changes cuz it seems like only a handful for adv-4u? ill start: Advanced: - more detail on the extent of understanding expected of continuity and limits. not necessarily new content. - 'Graphical transformations' e.g. dilations now moved from Year 12 to Year 11 -...

same

apparantly the rate of expansion is accelerating. literally third derivative type of thing

hope you guys made yourselves stand out

the only major change i can see for maths is introducing 3d vectors in 3u. in fact most of these syllabi have little to no changes

no. theres no such thing as bs. everything you say needs to have purpose and meaning. you really need to know your theory well and use terminology correctly and where its relevant. if the marker doesnt see those buzzwords, youre not getting the marks. also you need to include calculations and...

i shouldve chosen this tbh and not actl

i was telling people last year to not underestimate the marking criteria of an easy exam and i got nerd emojied. all of you need to be seperated into bands one way or another and nesa will always find a way to do so. if its an easy exam, then they will give less marks to responses that only...

i dont like the terms 'more educated' and 'less educated'. like what does that even truly mean. someone can easily go to uni, learn jack and just pass courses, then get a degree at the end and be considered educated. in my opinion, i think the key distinction to be made is not someones...

theyre not meant to be on the graph its not a typo

ye exactly. 2021 felt more like a trial exam than anything. 2021 q14 is also radically different as it was many self-contained problems rather than a small number of significant ones

youre quite the wordsmith. nicely put

^^^^ i haven't seen a single set of solutions that uses the actual intended method without projections

for 16 c i), the non-otherwise approach is to create a vector perpendicular to B called C = (b2, -b1). area OAB = 1/2 * |OA||OB|sin(<AOB) = 1/2 * |OA||OB|cos(90 - <AOB) = 1/2 * |OA||OC|cos(<COA) = 1/2(OA . OC) = 1/2(a1b2 - a2b1) since |OB| = |OC| pretty sure this is the simplest you can get.

people think its harder than 2022 when its a bit dubious whether thats true. this years exam way more 'abstract' apparantly which i didnt really get that vibe tbh

its ok we can all agree 2021 will forever be the easiest from the new syllabus. im not afraid to admit it

14 a was easy if youve done past papers and seen it, 14 b i) everyone wouldve gotten, 14 b ii) the hard part is knowing to use double roots but thats pretty clear after realising it needs one real solution. 14 c i) ill say is a little hard but theres a really smooth method for it that only...

question 14 last year was just hell with that vector proof, projectile and stats qs. this year it was way more approachable
