harder than 06 and o7? and how much do you guys think the subject will scale from a 35 ? 10, 11 points
-
It was harder than 06 and 07, but not as hard as the 03 or 04 paper, or as I expected. Considering exam 1, I thought they were going to pull a really tough exam 2 on us.
But still, there were some really tricky questions. I think it'll scale about 10.
-
It scaled 10 last year and both exams this year were harder so i would hope that means a larger amount of scaling. Maybe 11 or 12
-
have you guys considered that we might just think it was hard because we sat it?
i didn't think it was a really difficult exam but it was tight time wise. i didn't have time to check over my solutions =(
i thought the exam was quite strange and i didn't think the course got tested very well.
it'd be awesome if it scaled more than 10 though. has it ever done so in previous years?
-
yeh i think 03 04 it was 13

yeh i found last years really hard but today was ok except multi

does scaling rely on how hard the exams were?
Because the A+ range is just as large regardless eg. 9% will get A+ and thus they would be the top ranked study scores counting downwards?
i don't think that just because an exam is harder the scaling will be larger.
my belief was that scaling was based on the strength of the cohort taking the subject and their relative scores in other subjects comparative to the subject in question.
ie.
if a large proportion who are taking spesh are getting mid to high 40's in most of their other subjects
yet end up with a 38ish score, wouldn't normalisation of the study scores [done by vtac not vcaa] give the scaling?
well thats what i've been led to believe thus far, and it seems to be a pretty solid method of working out scaling in my mind
but i could be wrong and probably likely to be...

i have no idea about how all this works killsdow. i don't even know what cohort means :) i think what you're saying makes sense though.
what do you guys think is needed as an absolute minimum in both exams for 40 raw?

What you said makes a lot of sense. But my teacher said that it is difficulty that decides scaling but i can completely see the logic of what you said. If someone can give the official answer it would be good

alrite guys what would g1 c+, g2 b+ and g3 C get me in spec raw, and then standardised,,,, --- these r following 2007's distribution?

Easier exam, but longer. Multi-choice was easier to copy off the person next to you than actually do yourself.

cheap
just...reallly long i agree D:

Today's paper was not as brutal as Exam 1, but it certainly was not easy.
I'm guessing the raw study scores for this year might scale like this:
(30)[42]
(35)[46]
(40)[50]
(45)[53]
(50)[55]

From what I understand (and heard) though I could be completely wrong:
Your raw score is, in effect, a percentage/ranking of how you went compared to the rest of the cohort. Regardless of how hard or easy it was, you probably will end up with the same raw score. For eg. If it was really hard you still would've been say the average student, and hence got a 30 raw.
The actual scaling of the raw score, depends on how hard the subject is in general compared to other subjects. The basis of assumption is that students are just as 'intelligent' at specialist as they are at say, english. You may get a 40 raw for English, but only a 30 raw for spesh. This indicates that spesh should be scaled up 10 (if you were the only one doing the subject).
Basically how much scaling is calculated based on how the Specialist Cohort goes in other subject exams. What they can see from this is, for example, 80% of the same spesh students are actually in the top 30% of methods (if they do both subjects). So specialist is 'harder' then methods, and needs to be scaled up, so that (for example) 80% the scaled scores in spesh are 40+ and 30% of the methods scaled scores are 40+ . It then just gets more complicated when you add mulitple subjects and multiple combinations. Of course, because they do this on a large scale so all the averages areduces the error from indivduals.

There's no correlation between difficulty of exams and scaling but. Study scores are allocated solely on rankings, so it doesn't really matter about how hard the exams are. Scaling only takes into account the strength of the specialist maths cohort.

You posted just before me =P And yes, what you said is true, as I've said in my post.
