I didn't see any threads for it this year, how did you guys do? I felt that the Core section was tougher/longer than usual, and I couldn't double check.
-
Yeah, it was longer than previous exams. Anyone know if that one question was interpolation or extrapolation? I’ve gotten both responses from people so I’m kinda freaking out
-
It was extrapolation... Unfortunately, I put interpolation though :'(
-
my brother who did the exam, said it was extrapolation as well
-
It was extrapolating because there was no original data value at 65 :)
-
I know its hard to tell, although, if im ranked about 3 or 4 with a solid top end and got 40/40 and 59/60 on exam 1 and 2, respectfully, would that mean i can get a 48-49, even a 50?
Much appreciated
-
I reckon that'd definitely be possible - if your SACs scale to 100% then you've definitely got a shot at a 50!
Just to provide context, with a 39/40 for Exam 1 and 58/60 for Exam 2, I've been told that a ~46-48 is possible, so you should be on track for a ~48+.

Hi guys,
what did y'all do for the question where they gave two points and asked to use it to find the equation of the line?
-
Hi guys,

you could get the gradient from the two points.
after that you can substitute one of the given points and solve to find the intercept

Hi guys I don't really know anything about how study scores work for further so I wanted to see if anyone else knew.
I got a 40/40 in exam 1 and I think I will get 58/60 in exam 2. I was in the top 5 of a strong cohort with around 100 people.
Could that get a 48 or 49?
-

i thought i saw the value within the range, so i put interpolation :/
that sucks, i should have read the question properly. idk how i didnt see that

Hey there!
That definitely sounds possible! I guess there is a larger element of uncertainty with the way exams will be marked and scaled, but with your ranking and exam marks, I reckon you’ll definitely be able to get a 48-49, maybe even a 50.
-
I actually found it easier than the multiple choice despite not really doing much study for either :P

Could you have also just used CAS to calculate the slope?
-
For the last financial question, is it 150 or 99 months? I'm seeing split answers everywhere.

Definitely in the range of a 48-49 if you get those scores and your cohort does reasonably well

I got 150, but don’t trust me on that one. after all I messed up the extrapolation question 🥴
-
wait, where are y'all getting the answers to this exam. does anyone have a copy that a teacher has done?

we're comparing our answers from memory -u-
there was someone who posted teacher answers for exam 1. maybe they'll post them again soon, i need to know how my results are :/

Check the FB vce discussion space. Someone posted the suggested solutions.
-

Can someone confirm this? Could we just use the a and b value from CAS reg function?

thanks heaps. looks like i lost another mark forgetting to convert the 0.3% from the 3 standard deviations question, and i wrote (age)^2 instead of (mean age)^2 in the regression equation. today def isn't my day, do you think i could lose marks for the regression mistake?
-

I don't think so. The question specifically said to "use the two points" which were given, thus you had to calculate the slope based off those two points.

Hmm.. yes I think you will lose a mark for that as it specifically said the MEAN age, not just the age. In the same boat as you, lost a mark on the extrapolation question as well as the standard deviation question.

bro we were rushed for time, this fkn sucks. at least we did our best though :/

I got 150, checked my answer like a million times so hopefully its correct :)

Hi guys,

ahh which question was this, was this the one where you had to write the equation of the line in the boxes to like 3 sig figs or something, i cant remember the question now im scared lol

Hey guys, I was just wondering
I've averaged about 96% and I think I'm ranked third in my cohort, but for safe measure, I'll just say 5th or something out of about 70 students. If I got 40/40 for exam 1 and 57/60 for exam 2, what study score could I be looking at? I was really hoping for a 44.

I would be thinking something like 47-48 (so highly likely to be above 45 assuming your sacs stay around the same score).

Really? I thought I'd be looking around a 43-44

Well, the possible range is quite wide depending on how your sacs scale. You are probably maxing out at 48 and then depending on how your cohort went on the exam you can either maintain that or your study scale may be dragged down to the low-mid 40 range.

can u help me out sine
i think i'm top rank in a low cohort, and my sac average is somewhere about 99%. from the predicted answers, i think i got full marks on exam 1, but i've dropped at least 3 on exam 2 this morning. what kind of study score do you think i can expect?
-
Hi Guys,
I'm just wondering if a 50 is completely out of the question with rank 1, a 38/40 on Exam1 and a 60/60 on Exam 2? I assume it is but I just wanted to check. I also was wondering if there has ever been times when losing two marks gets you a 50?
Also, with this information what study score do you think would be expected?
Thank you!

Based on the data from previous exams and what was required for a 50 in those exams the max you can drop is 1 mark for a 50. I have never seen anyone drop 2 for a 50. Your problem is also coupled with the fact that marks on exam 1 are worth more than on exam 2.
Having said that, study scores are calculated dependent on the exam of that year and how the state goes on it so whilst it is extremely likely dropping 2 marks will yield a study score less than 50 the probability is not 0.
Assuming your sacs are consistent with your exam scores I think you would be able to get a 48-49 study score.

feel kinda awful about this exam, i dropped five marks that i know of, 4 of them were really stupid mistakes (ended the line of my box plot at the wrong point, positive correlation coefficient instead of negative, used a y^2 transformation instead of x^2).. i think i dropped less marks in exam 1 but i haven't checked, my sac marks this year weren't great either (my cohort is strong-ish?) so i'm not expecting a great study score

a y^2 transformation would've been fine as well!
-

wait really? a friend told me the question said to apply the transformation to x but i couldve sworn it said you could use any transformation so i chose y^2
-

Omg, I actually didn't even realise it said to apply to it the x variable 'mean age' (Just looked at the pdf version of the exam). Sorry, so a y^2 transformation is actually incorrect, my bad!

For networks, which 4 activities had a float time?

What score am I looking at?
Rank 1 in a strong cohort so sac probs scaled to 100%
38/40 exam 1
60/60 exam 2
Thanks in advance

Hello, I did horrible in both exams due to nerves and was wondering what study score I can achieve.
SAC rank, I only know i'm at an A+ for my rank.
Exam 1: 37/40
Exam 2: 55-56/60
Is there any possible chance that I can even get a 40.

Try this thread as well for score predictions (:

For the last question in the data section where you had to apply an x^2 transformation, if I just wrote 'x^2 transformation' but didn't write the equation (ran out of time) would I get 1 out of the 2 marks available?
-
Hey there,
I'm rank 3 in a strong cohort with a sac average of 97%
I got 40/40 in exam 1 but absolutely messed up exam 2 and got 55-56/60,
Do I still have a chance at getting a 47-48?

i think one mark is awarded for getting the right numbers (i.e rounding correctly) and the other goes for any semblance of the transformed equation but i'm not too sure.. i wrote a y^2 equation and i'm not sure if i dropped one mark or both marks too

100% in exam 1 and rank 3 puts you at a huge advantage! 45+ is definitely possible, but less so 48+ but only by a few marks assuming you dropped five marks in exam 2 (though anything could be possible, it's actually quite hard to tell but i wouldn't worry too much!)
