I would rather redo paper 2 than do a 7 marker proof on binomial properties oml

im afraid you're alone on this one

Istg imma crash out if there's a chunky combinatorics question this year.

I can definitely see a trig sub polynomials question tho since haven't seen one in a few years I don't think

If

Very decent chance this yr on p and cs. barely any was tested last yr. I'd argue as well that barely any probability questions were present either.

they decide to test this they js wasting marks fr fr

 

[kkk579]

they're still good practice, especially when hsc decides to pull some random questions out that other schools dont test
i took a look at girra and penrith, good recommendations. thanks

i think ruse is quite reasonable. nsb a little less, ppl say not to do them because theyre horribly written or smth

Im praying for no probability and pc stuff omds

guys this might be a silly question, but why are the hsc ext 1 exams out of 70, if we get a mark out of 50?

guys this might be a silly question, but why are the hsc ext 1 exams out of 70, if we get a mark out of 50?

I’m guessing because ppl doing ext 1 have it as 1 unit while ppl doing ext 2 have it as 2 units, so 70 marks is the rough midpoint between 100 and 50

I think it's due to it being 2hrs long instead of 3hrs. So only 2/3 of 100 rounds to around 70 ish

It gets rescaled based on whether it's worth 1 or 2 units tho (4u ppl)

So guys... based on the difficulty of 4U math and 2U math, I think it is safe to say to do the hardest papers for 3U because NESA punished us

What do people think was the hardest ext 1 hsc paper since new syllabus? Just want a reference cuz I'm expecting it to be hard

2022 > 2023 > others > 2020

can someone try doing this?

421?

binomial probability
p = 2/3
for P(x≥5) = 6C5 (2/3)^5(1/3) + 6C6(2/3)^6
then x 1200

yea u got it

does anybody know what raw is required to align to a high E4 (97, 98), and how big the margin between each mark is? if you have any examples, plz tell!

on the rawmarksdatabase, in 2024, a raw 84 became a 94, and a raw 87 is a 96 - it's insane to me that a 3 mark gap in raw was a 2 mark gap in aligned. do they just lump all of the higher ones together, in that case?

thanks guys!

I think the idea of alignment is just to rank you against the state. It makes sense since if u lose 2 marks, many people probably scored higher than you already. this is cause the tests are only out of 70

probably around a 95?

I can't believe 5 people who couldn't even answer question 11 paid for their raw marks

Alignment works by a committee judging what raw mark gives 90, 80, 70 etc. Every other mark in between those cut-offs is linearly interpolated. So when a 87 aligns to a 96 for example, it doesn’t align exactly to a 96. It’s actually rounded to 96.

the graph don't look linear to be tho
