im pretty sure you can state a=x^2-y^2 and b=2xy and then do it by inspection from there.

Ye i have looked at previous cohorts, and they tend to get between 5-7 95+ for chem, have no clue for phys tho, i was just wondering what would it be respective to the state in terms of placement. ye i meant aligned, 95 raw is a bit too hard.

Would anyone know how many students get 95+ in chem and phys each year?

2 tips that i think are the most important for assessments: -For internal assessments, try to finish most of the content that you are going to be assessed in that term at least 2 weeks before your actual exam (I finished most of my content 3 weeks before). -After finishing content, find the...

i know ppl who have copied essays from the person who was topping english in my school, most of them got 91-93 externally, i dont think you can get a high b6 with a memorised essay but you can definitely get a satisfactory mark, which is good if you dont care about english.

oh i see where to use it now, thanks for the working.

Dont get how (i) relates to (ii), but i think u might need to use kings rule for (ii).

In Australia vaccines arent compulsory, so if u dont want to u dont have to. (this is for everyone in australia)

wouldn't this mean that most schools would have to cancel their trials or have online ones, except the very few that have students only outside the LGA's.

You are doing well, especially since we are still a while away from HSC. All that matters is that internally you do well in terms of rank, and by the time externals happen you can easily get into high 80s to low 90s raw mark wise.

ye i feel the same thing with hsc q's vs trial q's but i feel it has more to do with the presentation of the paper being a lot cleaner aswell, the ruse trials are quite hard, although i found the 2020 paper more challenging compared to the old syllabus papers (the complex/integration/mechanics).

ye 3u is stress cause you can rank can get wrecked by 1 mark lost ye im not too good can finish papers in like 2 hrs., i remember ppl from last yrs cohort on bos who could finish in 1.5 hrs.

its actually too easy now, the only questions I get wrong now are the ones that require an abstract way of thinking these are like 3 markers between q 14-15. q16's are a breeze aswell.

its just a constant of proportionality, it doesnt really mean much in highschool physics but im sure its derived from somewhere, i think maybe maxwell cause its in his speed of light formula.

are there even 600 schools in nsw

yep, and for the actual application i think they care about the hast test results more than anything else.

for hast, there are 4 section (like yr7 selective test), u cant really prepare for it, u can do some yr7 ga exams cause the difficulty for the abstract section is similar to that of selective. For math is more of just problem solving skills, so u can just find math papers which are suited to...

in order of increasing bp: amine, aldehyde, ketone, alcohol, carboxylic, amides. the explanation for bonding: amine: has hydrogen bonds due to the -NH functional group, but N is the least electro-negative so it has very weak hydrogen bonds. aldehyde/ketone: has the carbonyl functional group...

it gets absorbed into the lattice arrangement of the metal, this is because metals are a lattice of delocalised electrons. This tells us that the cathode ray is a particle which cant go 'through' metals but are absorbed (the absorbing part i wouldn't mention in a question as the questions...

You are meant to use the sum of altitude and radius of earth.
