I know it's more complicated than this but
For the scenario:
SACS: (In rank order for unit 3 and 4)
Student B - 1
Student A - 2 (Difference by TWO marks)
Student D - 3
Student C - 4
Student E - 5
For the exam (rank order):
Student A - A
Student B - B
Student D - B
Student C - B
Student E - B
In terms of the general "highest ranked student gets highest exam mark as their sac mark" Would student B get an A for their SAC mark, despite only being ahead by 2 little marks? And Student A get a B?
Oh and by the way the teacher is unlikely to 'even out marks' or anything.
-
STUDENT A
SAC Marks: B
Exam Marks: A
STUDENT B
SAC Marks: A
Exam Marks: B
STUDENT C
SAC Marks: B
Exam Marks: B
STUDENT D
SAC Marks: B
Exam Marks: B
STUDENT E
SAC Marks: B
Exam Marks: B
So yea, Student B would get an A for SAC Marks, even though it was close, student B was still ranked 1st so Student B's sac marks would be the highest exam mark. Yea, in cases like this the system is probably slightly unfair, but if you take everything into account, It works well I suppose?
-
i thought it was, the person who gets the 'highest exam mark gets the highest sac mark in the cohort as their sac mark'?
so given that student A was the highest ranked person in terms of exams, shouldn't he get his sacs scaled up to the highest one obtained in the cohort?

nope
SACs are moderated against exam scores, using SAC rankings.
exam rankings mean little.

So Mao, despite the 2 mark difference, individual A would still get a B? :\ (for sacs)
-
Wow it seems SAC's are NOT meaningless afterall..

I'd assume so
but there are a couple things to keep in mind also
1. statistical moderation is approximate, not exact
2. calculation of study score is irrelevant of grade, but rather the raw score [which we don't really get to find out]
if the two students have similar abilities (as demonstrated by the close tie in SACs), I would also assume that they'd perform similarly in the exam. that is, it might be a low A and a high B and are really only a couple marks off each other. the impact is not great, though it is a kind of reward for student B for doing well consistently for the whole year.
ReVeL: SACs are important, but not important enough to stress over.
It accounts for at max 50% of your score [SATs are different]. I have heard people say "I'm not ranking high enough so I can't get a good score", which is absolutely bullshit. Even if you have epically stuffed up a SAC, so long as you do well in the exam, you can still get a reasonably good score. [just saying this out loud, not in reply to anyone's post in particular]

and hopefully it helps to be in a good school lol. ughh, stupid methods sacs.
-
i think there is a lot of stuff we dont really understand about this.
-
I heard that at VCAA there is an actual formula on how to calculate the study score, what i dont understand is why dont they tell us how they actually do it, i mean i dont think there is a way to cheat the system because at the end of day it relies on your exam marks heavily. LOLS yay 50 posts finally ;D

it's not so much a formula, but moreso a process that includes a lot of data crunching of practically everything.
its not so much that releasing the process allow people to "cheat the system", but it's more that it'll be meaningless to everyone because of its complexity due to all sorts of variables such as statistical moderation, etc.

um but if you're ranked near the bottom, is there a point in trying for the exams. coz you'll get a bad SS even if u do ace the exams.right..?
-
so if your ranked first on exam you get rank1 sacs
hypothetically
what if your schools highest sac mark is a D? and you get A+ on exam
what would you get then?
wouldnt the D go up to a B or so?

If you are ranked first in the sacs, your sac mark will be moderated against the best exam result. So to answer your question, the D ---> A+ for sac result.
-
so what happens if your rank 1 with A+ on sacs
and top exam result is a C+
will you get a C+ SAC

yep

wrong.
exam has very high weighting in the calculation of your study score, from half to two-thirds. It is the most crucial element of your SS, and regardless of how your ranking is, always try in the exam.
SACs are also moderated against exams, so doing well in the exam would indirectly benefit your SAC scores also. As well as some claims that doing extraordinarily well in the exam [in relation to your cohort] can modify your SAC ranking altogether.
in short, not doing well in SACs is not a reason to not try in the exam.
-
You know how teachers try to rank the cohort so that the best result is achieved for everyone?
i.e. Teachers try to make SAC ranking = Exam ranking
If someone is like, really really good at a subject, but due to bad luck did bad on SACs and is ranked 2nd or 3rd, do you think it's possible for the teacher to change the rankings based on expected exam performance (from practice exam results) to get the ranking right or would this just be unethical?
-
imo that'll be a bit unfair, SACs should be an accurate reflection of the person's abilities from their performance throughout the year.
say if I decided to do no work at all for the whole year, and then fire up for the exam, and have my SAC ranking changed because of that, then my SAC GA is really saying "here's an awesome grade for being lazy for the whole year".
-
At least it's not like other systems in other countries where they don't have SAC's, but only sit one 3-hour-exam at the end of the year to test their abilities. No GAT either, no moderation... I can't say I hate our system. :)

if everyone has to do the same subjects, and the only assessments are the exams, then there is no need for moderation :P
-
Hehe... True :)

that'd be so much better. i hate SACs, massive waste of time.

Pretty sure they do that at my school and also a few other schools I know from friends.
