wait gang insanely stupid question for maths adv. ik the order of transformations always has translation last, but i'm doing a bunch of hsc questions and every time i get a question they always do the translation first so i keep getting questions wrong. am i really stupid or am i missing something?? lmfao

I think the questions didnt specify a specific order, bc l came across cssa papers that had translation 1st. But when you get a graph and are asked to "transform" it, you ALWAYS do dilations first.

Like you're not wrong, but when you write stuff down, and q mentions no order, you can write down whatever. But drawing? No.

does anyone know what the relationship between internal rank and hsc mark is? like if i came first in a subject at my school but then i dont get the highest raw mark out of my cohort in the hsc, do i get that mark or someone elses? i have no idea how ranks or scaling works its too confusing

im gonna show u an example that helped me understand scaling, if ur still confused then im sorry

sarah came first internally after all her assignments were done for mathematics advanced
adam came second
conrad came third

their overall internal marks were respectfully 90, 87, 85

but nesa doesnt give a shit abt their internal marks bc thats relative to the school, and every school has different assignments so thats chucked aside. they only look at the rank

after the hsc, this was their exam marks

sarah got 88
adam got 95
conrad got 91

in the hsc exam marks, this is their ranks:

1. adam 95
2. conrad 91
3. sarah 88

this is their external mark, which means they get to keep 50% of it. the other 50% comes from their internal mark. but how does that come about? moderation by looking at what the cohort got in the hsc

in the HSC EXAMS adam got the highest mark, placing 1st. yet internally, he's still second.

because sarah came first internally, she receives his mark as her INTERNAL mark, making up the other half of her hsc mark for maths

this means sarahs mark is calculated by the average between 88 and 95 (88+95=183) ⇾ 183 divided by 2 = 91.5, which is rounded up to 92 since hsc marks r never .5

so, sarahs hsc mark for mathematics advanced is 92

adam came first externally and second internally. no, sarah did not take his mark. thats not how it works.

adam keeps the 95 as his external mark

nesa looks at the cohorts hsc marks and selects the 2nd highest mark to place as adams internal mark

conrad came 2nd externally with a 91, so obv with the average calculation, adams overall hsc mark is 93

this shows that despite sarah coming first internally, adam still managed to get a higher mark than her in his overall hsc mark

and obviously with conrad, he came 3rd internally and 2nd externally, making his mark a mix of his external mark of 91 and sarahs 88, with his overall hsc mark being 89.5, rounded to a 90

this is now their overall hsc marks

sarah: 92
adam: 93
conrad: 90

I would like to add that to my knowledge, it is not quite "oh 2nd place internal gets 2nd external mark" - this would probably be a little unfair
This is what I believe the process to be

1. You get your internal ranks
2. Say the highest internal mark was 60 and the lowest was 20, and the highest in the HSC was 80 and the lowest was 60 - the highest rank internal will get 80 as their internal mark, and the lowest rank internal will get 60 as their internal mark (externals are not affected)
3. If you're in between, then you get moved accordingly! So if you say ranked 2nd with a 54 internally, that would probably get changed to approximately 77. Note that though your actual internal mark doesn't do anything, it still determines how well you moderate, so it's not purely rank that matters.
4. Then they average this score and your external mark!

I may be wrong, but I know that though your internal rank is definitely important, they do account for the gap between people's marks, so it is not entirely a switcheroo of external marks

NESA cares more about distance of ranks rather than ranks in isolation. If hypothetically the distance between rank 1 and 200 was 10 marks after averiging internals and ANYONE within that cohort gets 100/100 in their exam, then ranks 1-200 will all get an ASSESSMENT MARK somewhere between 90 and 100 (note that rank has NO IMPACT on your EXAM MARK). This is why the top schools are consistently top as they have very small gaps in between ranks. After that, they just average your exam mark with your moderated assessment mark and round up to the nearest whole number.

hmmmm im sure they dont rlly look at internal marks cuz ive seen ppl get dragged down bad just cuz their cohort didnt try in the exam, with their external marks of like 94 turning into an 87 cuz their rank brang it down

That was probalbly because there was a huge distance between ranks.

Nah this is unrealistic, Conrad is always number one

does anyone know what SRS looks at? how likely am I to get a high selection course from SRS compared to direct entry?
I had pretty good marks in year 11 + my hsc maths results, but for some direct entries, my careers advisor told me to not put them from highest to lowest atar, and now i kinda feel like that was a waste bc the selection rank for my first preference was really low (85) and i probably couldve got it without early entry. now im wondering if i can give the courses with higher selection ranks another shot by putting them in my SRS?

All of these people get these extremely high marks but then will probably end up doing the same degree as someone who only got a band 4-5 few years later. Its funny to think about
Sweating your ass off just to do the same course as someone who got in through early entry and whatnot lmao
