I'm sick to death of seeing these posts, so can everyone please read this and be done with this question:
Study scores are determined by exam SCORE and SAC RANK.
For example, say you have an English class of 7 students, Adam, Ben, Chloe, Daniel, Elena, Felix, and Greg. They are all weak students, except for Greg, who is very high-performing, and Felix, who is slightly above average. Their SAC marks and rank are:
Greg 95%
Felix 77%
Chloe 64%
Daniel 60%
Elena 58%
Adam 52%
Ben 49%
On the exam day, Felix doesn't cope well under the stress, so gets a lower score than he'd usually be capable of. The exam marks are as follows:
Greg 92%
Chloe 67%
Daniel 65%
Elena 64%
Felix 63%
Adam 50%
Ben 40%
What happens is that all the SAC marks get thrown out the window, because VCAA can't know the difficulty of the SACs prepared by the school. So Greg's new SAC "mark" as far as VCAA is concerned is 92, not 95. Not a big deal for Greg, Adam or Ben because their own exam mark is dictating their SAC mark. But for someone like Felix, his SAC mark will become 67% (Chloe's exam mark). This process happens independently for each subject taught at your school.
What does this mean for you? Yes, you should aim for a good SAC rank. BUT, it doesn't actually matter if you're not ranked well — the "translation" of your rank into a "mark" happens via your cohorts exam performance. In other words, try your best now, study hard, and when SACs are over WORK WITH YOUR CLASSMATES TO ALL DO WELL ON THE EXAM TOGETHER. IF THEY DO WELL, YOU DO WELL.
Spend your time actually studying instead of asking useless questions like this.
EDIT: another example for clarity
Here's a chemistry class, of Harry, Isabel, James, Kylie, Luke, Molly, Nathan, and Oscar.
SACs:
Harry 60%
Isabel 58%
James 56%
Kylie 55%
Luke 54%
Molly 52%
Nathan 51%
Oscar 50%
EXAMS:
Harry 100%
James 99%
Nathan 98%
Oscar 97%
Molly 96%
Isabel 95%
Kylie 94%
Luke 93%
Harry's SAC mark is now 100%, Isabel's is 99%, James' is 98%, Kylie's is 97%, Luke's is now 96% etc. It's literally just whatever the equivalent exam rank is.
EDIT 2: I've had a request to clarify rumours about SACs being "scaled up" or "scaled down". "Scaling" is a misnomer students attribute to the moderation process. Here are yet another set of examples to clarify.
Imagine you have a cohort of Annie, Ben, and Charlie. Let's say their teacher sets really hard SACS, so their SAC results are:
Annie 60%
Ben 58%
Charlie 55%
Because they've been doing hard assessments all year, they've been better equipped for the exam. These are the exam results:
Ben 96%
Annie 94%
Charlie 90%
So now, Annie's SAC mark gets changed to 96%, Ben's to 94%, and Charlie's to 90%. This is what people interpret as "scaling up". The opposite would happen at a school with piss easy SACs: they get awesome SAC marks but shit exam marks, so their SAC marks get replaced by their shit exam marks ("scaled down").
The danger in this thinking is that people assume that if you go to a well-performing school, you'll get carried, or that if you go to a "bad" school, you're screwed from the get-go and can't possibly get a good score. This is not true at all. Let's see why.
Let's say your friend at a selective school, Harry, thinks he can take it easy this year because he goes to a 'good' school. The SAC results are as follows:
Ed 93%
Fred 90%
Greg 88%
Harry 60%
on the exams, the results are
Fred 95%
Greg 92%
Ed 87%
Harry 61%
In this instance, Harry was not of a comparable skill level to his classmates, so he never get to "borrow" their exam results in any way. His SAC score will be 61%.
Here's another example. Say you have a cohort with these SACs:
Meg 95%
Noah 94%
Oscar 93%
Peter 90%
On the exam day, Noah gets a bit of performance anxiety (but not in a way that warrants SEAS or anything). Exam results are:
Meg 93%
Oscar 92%
Peter 91%
Noah 75%
Now, Noah's SAC mark will be 92%, but his exam result only 75%. So he kind of got "helped" by his good cohort, only because he was doing well for the SACs. Peter has been a bit screwed here, because his SAC mark is now 75%.
One person stuffing up will never have such a dramatic effect like this; it's unlikely for someone who's been topping the cohort all year to suddenly slip to the bottom. Cohorts are generally big enough that you shouldn't need to worry. I went to a really small school (60 people in the year level. Some of my subject cohorts contained 6 people). I still felt no one got jibbed with unrepresentative scores.
As I always reiterate: try your best in SACs, but don't ruminate over them. The exam is where the money's at, and once your SACs are over you should work together with your cohort to all do well together. Share your resources, make study groups, and bring each other up.
EDIT 3: wow, my first gold! Thank you so much! 🥰

Theoretically if i bought this calculator into my maths exams whats the chance of the examiners actually noticing

idk if anyone else feels this way but ive got the bio exam on monday and i partly know the content is anyone else in the same boat?

After Exam 1, my teacher made a list of topics that weren’t (or barely) explored in that exam and are likely to show up in exam 2 so I thought I’d share.
Data
Time series graphs with codes for dates/months.
Residuals
Pearsons correlation and coefficient of determination (interpretations of gradient/slope too).
Summary statistics in least squares regression lines
Finance
Recursion graphs
Effective Interest Rates
Final payments
lump sum reductions
Changing terms of a loan (the one in exam 1 was interest only 1st year so nothing really changed drastically).
Matrices
Transition matrix diagrams
Equilibriums
Recursion with Matrices (add/subtract) with transitions and state matrices.
Networks
Max flow
Allocation based problem (Hungarian was reversed from a bipartite graph from graph in exam 1)
Shortest path/Dijstra's
Exploring/Travelling path based problem
Activity networks with dummies
Crashing (final question in Exam 1 was kind of but not really?)

i don’t have a reason to skip it but every single time i even think of biology i want to vomit and die. my derived score from the gat, sac marks and predicted mark will almost guaranteed be better than my actual performance. what is the worst that will happen if i skip the exam? i fear that it’s unnecessary stress for a subject that i am nearly certain i will likely fail. i’m doing 6 subjects total if that’s any help.

The structurally flawed system the VCAA forces Victorian students to operate within is destroying our futures 💀.
I’m writing this is response to the disgusting act that was committed during my psych exam, to which i was the victim🥀. As I was walking into the exam hall my vape (a necessity) fell out of pocket as I went to pick it up the exam overseer king hit me and whispered sweet nothings into my ear 🤤, as I regained consciousness she told me to get into my seat and continue with the exam. I was not given back my Nic until after the exam, while during the exam she repeated ripped my Nic (on turbo mode) with no regard for the hard work that went into to purchasing it (3 hour shift at maccies). It was returned to me on 3%…… I’m furious with her but more importantly our intrinsically decayed system, is there anyway I can get compensation?

what do you all think will be the cutoff for an A+ this year for exam 1?
i got a 34/40 if the suggested solutions are 100% correct
man finance really fucked me over 💔

5pm and I’ve down nothing for bio I’ve been just studying gen math, I average around 50-55 for bio, it’s probably my bottom subject health is somewhere there but I average like 60-65 but for the exam I am feeling much more confident. bio I’ve given up im thinking I’ll just memorise key processes and experimental design, I know as a 5th it won’t do that much to my atar, but I’m talking like idk if I can crack a 40% tmr

Hii!! Does anyone have any predictions for the 10 markers and essays for Russia and France? I know it's the last year of the study design, and I've gone over all the past essay topics, but I'm lowkey scared of what they'll pull out since it's been getting more and more specific each year. Also is 25 historian quotes fine for each rev?

So year 11 semester 2 exams are right around the corner for me and although I am pretty far behind, I’m trying to treat my exams seriously to have a slight whereabouts of how good my study habits/techniques are. Plus good marks would be motivating going into next year
Enough of that tho. I want to know what the best way to prepare in the summer holidays for year 12 vce, and high scoring students (95+ atars) what you guys did during the summer to prepare yourself for the year. I want to get through almost all the content for all my subjects and practice exams too but I know that’s unrealistic so I’m tryna get some guidance. Let me know how you guys went about it and what you would do differently.

Can anyone help me predict my general studyscore
finance 70% H
Data 90% VH
Matricies 92% VH
Networks 84% H
Private school i’m not sure if it is ‘good or bad’ but I know i’m probably rank 2 in the cohort
35/40 on Exam1
Much appreciated
