All discussion relating to the 2013 exam is to be posted in this thread.
Wishing everyone all the best.

Anyone else find that really, really easy? I finished 1 hour and 30 minutes in after checking around 3 times...
-
Was fairly easy and straight forward. Most people from my cohort walked out with a grin. We might see a higher A+ cut off
For me I'd say I lost 8 marks max
-
I'm feeling pretty good, answered everything with time to check most of it over :)
What did you guys get for multi choice question 8 (I think) where you had to choose the most efficient algorithm? I said D but it was between that and B.
-
I thought it went pretty well!
For that question I put B, it was the only one that set the variable outside of the loop, thereby reducing the number of lines that had to be run.

B and D both set the variable outside the loop, however D had the variable set to 6.28 and in the loop only multiplied 6.28 by the radius. B had the variable set to 3.14 had it multiplied by 2, itself and the radius.

Ah I see, I must have missed that then.
-
The answer to that multiple choice was B, because they made a mistake in using the variable, which was mypi or something in A and C. They broke the code and did my2pi instead of 2mypi, thus redering option C and A invalid. The answer was B. Option D included too many characters and thus B was comprised of lesser symbols. That is what I based my choice from.
Also, the multiple choice where you had to choose for the lady at home to use a VPN or an Intranet or Broadband or the Internet. I chose the Intranet because VPN - you need to be in range of an existing network and since she was at home, there was no network. Broadband and Internet are stupid, thus intranet was the right choice, no?

Yep, I chose intranet for that one as well.
-
The answer was VPN as she is at home and intranet requires LAN internet isn't secure so VPN is the best option.
For Q8 it's D , and you can name it whatever you want, so it can be my2pi if you want it to be.
-
I also chose VPN and D for q8 but not completely sure :-\
-
Up to you guysss, but I was quite certain of my answers.

No it can't be my2pi. The variable was declared as mypi, and by saying my2pi, you were breaking the variable and hence causing an error.
-
Easiest exam I've ever sat, in all honesty. Perhaps it was how much I had prepared for it, but my classmates (aside from a handful of people who haven't paid attention all year) also all walked out with a huge grin. I'm a lot more confident in gaining a high study score, now.
No it can't be my2pi. The variable was declared as mypi, and by saying my2pi, you were breaking the variable and hence causing an error.
Also, in regards to this, I agree. The variable was stated as mypi, and it looked like my2pi was there to confuse us. I chose B, also, because the variable was set outside the loop and because whilst D did the same in regards to where it set the variable, my2pi wasn't the original variable name.
-
I was so happy with the exam, fairly straightforward with a lot less ambiguity than I have seen in practice papers. There were definitely a few questions I wasn't prepared for but for the most part I was able to sort out an answer that made sense. The reduced ambiguity was complemented by a significant increase in the amount of algorithms we were required to write, which I was very pleased to see as I think there needs to be a push for better understanding of algorithms. We weren't just asked to write a list of steps in algorithm form or produce a simple swap, there was some real on the spot coding that made you think at first and I enjoyed that. Based on the above evaluation, It'd be nice to see the cutoffs move up a little but I think they'll stay roughly the same because the state tends to struggle with algorithms.

Nah, pretty sure D was correct, there are no 'errors' in an algorithm, you can't 'break' it because it isn't code being executed by a computer, it's just pseudocode, a set of logical steps with no syntax or strict rules that seeks only to convey the logic of a solution. As a result, using a variable my2pi instead of mypi is no issue at all, it's actually a smarter way to go about the solution, multiplying the 2 through first and using a constant of 2pi instead of pi for the calculations.
This question was about efficiency, asking which of the four solutions completed the task in the most efficient way. Since it was implied that there were multiple circles to have their circumference calculated, it's therefore a good idea to do as much of that calculation at the start (outside of the loop) as you can, because if you're doing it inside the loop instead it's just needlessly repeated calculations as you are running it multiple times. As a result, it's best to bring out the declaration of the variable (some options had the variable declared inside the loop, which meant lots of wasted declarations since the value never actually changed) so the other two were the more efficient options. Of the two, one multiplied the constant 3.14 by two each iteration and the other just used the pre-calculated value of 6.28, removing the need to multiply 3.14 by 2 in order to find each and every circumference. This is why I think D was the correct answer.
As for why it referred to mypi in the question, imo it was just to clarify that pi was the be taken to 2 decimal places.

I chose the Intranet because VPN - you need to be in range of an existing network and since she was at home, there was no network.

I don't think the answer was intranet, I think it was VPN.
Where did it say there was no network at home? If there was no network at home, there would be NO way for the woman to connect to her work. An intranet would not be appropriate as the work is in a different geographical location (an intranet is confined to within a LAN, it's an internal mini internet) and this means the intranet is not able to branch to the woman's house in order to provide a connection. The option internet would branch between her home and her workplace, and it could be argued that a broadband connection to the internet could be used to achieve this connection, but the important part of the question was the security of her connection. A VPN fits perfectly, it's a secure connection (as specified by the question) to a remote private network (her work network, which could even be an intranet) through a public network (in this case, the internet, the link between our lady's home and her work).
I'm fairly confident in my answers, and a few of my friends got the same answers as me, but I guess we'll never know until the report comes out next year.
Does anyone remember or did anyone write down question 9 of MC? I made a mark next to my answer for it, but I can't remember what it was. I went to compare it with my mate and it was the only MC question we answered differently, but neither of us could think which question it was.

That was my thought path for that question, as well. My dad was in a similar situation with his company a year ago so he asked me to help them set up a VPN in order for him to remotely access files he needed from here. And since he works for a company that has certain "trade secrets" and what have you, even the IT Techs from his office agreed that a VPN was in fact the best idea. That said, I can totally understand why some people chose intranet.
-
Which multiple choice are you referring to?
-
I found that the exam was a bit harder than last year with a bit more focus on pseudocode, but I was quite well prepared and only had difficulty in the pseudocode question in section B which involved finding the highest age or something on those lines.
-
The one in which the woman was trying to securely access her work from home.

That question was somewhat difficult, but I end up leaving it and then coming back to it later. I can't quite recall what I did, though, but I'm fairly certain I did that one right. Personally, I found last year's slightly more difficult than this years. Not entirely sure why, though, haha.
-
Last years one focused more on theory than this year.

Yeah it was about some UTP cable company, it wanted you to decide which layer of the OSI model that the cable would interact with.
-
Physical cables operate at layer 1.
-
Physical cables operate at layer 1.
Yeah, my answer was the physical layer. I think there might have been some confusion though as the book states that ethernet protocol operates at the data link layer.
-
Yeah, my answer was the physical layer. I think there might have been some confusion though as the book states that ethernet protocol operates at the data link layer.
That's correct :) Ethernet protocol operates at layer 2 (data link), but the physical cable itself directly operates at layer 1.
-

damn, i did say layer 2 because i thought the question was asking about the ethernet protocol, since it spoke so much about it. dat gotta pay attention to wording. oh well if thats the only MC i stuffed up i'm happy
-
yeah I said layer 1, mostly because I just assumed they didn't expect us to know anything beyond layer 1 in the OSI, but I did spend a while deciding between 1 and 2
-
yo silverpixeli was that our only difference in the MC?
-
yup
-
Hey guys,
Thought the exam was okay, I probably should of done better considering my SAC marks were quite high, but oh well.
I know this is an unrealistic question to ask a day after the exam, but could anyone give me an indication of what SS i could get with a 75/100 on the exam and average SAC mark of 94?
Thanks.
-
It's hard to predict really, the difficulty of the exam and your cohort strength affect your study score... So it's all really a guess.
But I'd assume low 40s
-
I know, its too hard to tell, but thanks anyway man :)

Wonderful. What is your source, and do you have a copy if the questions?
-
Whoops I misread your request, I do not have any solutions from an authority on the subject
HOWEVER, Silverpixeli (who is defs a 50 contender) got the exact same answers except for question 9 which has been discussed earlier in the thread. So yeah feel free to take those with a grain of salt :)

hahahahahahahahahahahahahahahahahahahahahahahahahahahaha
mark kelly's exam post mortem is currently under development, that will have all the questions as well as suggested solutions and should be out tonight or tomorrow at a guess

I am so keen for those. I read every question/answer several times so I'm fairly certain I'll be able to recognise what I answered for each. Here's to hoping we all did well, haha.

http://vceit.com/p/postmortem-2013s.htm
section A is all that is up as yet, the rest should be up soonish
-
Alright, that's awesome. Yeah, I guess the algorithm was D, and it was a VPN rather than an intranet. Everything else I got correct. 18/20. Very solid effort.
This years multiple choice was rather easy compared to previous years and the practice exams.
-
alright so the only difference he has to my answers is question two. I went with A (design), but he chose B (analysis) and then says 'It's a (non-functional) solution requirement, and these are determined during design'. That's definitely a mistake, either he meant to write 'analysis' or he meant to write 'A'. Thoughts?
-
THANKYOU Chazef! Exactly what I thought! It should be A
-
17/20 for multiple choice. Fairly happy, few silly mistakes but nothing can be changed now.

From VCEIT
a. What is acceptance testing and who should be involved in the acceptance testing of this software solution? 2 marks [6 lines]
Acceptance testing is when the client (or an end-user*) uses the software to determine if it meets the needs that were determined during system analysis, and to determine whether they should accept the software.
The dean of the plumbing faculty (or a plumbing teacher or plumbing student*) would be involved.
*There are different interpretations of "acceptance testing" and "user acceptance testing". Some people treat them synonymously; others use "acceptance testing" to refer to testing by the client (e.g. plumbing faculty manager), and UAT to refer to testing by a typical end-user (e.g. a plumbing student) to get a real user's perspective.
The study design (SD U4O2 KK07 - page 47) itself includes key knowledge of "criteria and techniques for testing acceptance by users of solutions" ; in fact the design ONLY refers to "acceptance by users." This actually strongly implies that the question is about UAT (acceptance by typical users) rather than acceptance by the purchaser of the software (e.g. the plumbing faculty's boss.)
I hope the markers are aware of this greyness of definitions. The Real World™ stubbornly resists the neat categorisations that VCAA loves so much. I will be on my Very High Horse if the examiner's report does not accept UAT.
Anyone mix them up? I'm pretty sure I mixed them up, I believe this part of the course is very 'grey'.
-
I said it was for the client as its "acceptance testing" not user acceptance testing.. is he saying thats wrong now? He clearly distinguishes the two on his website..

Yeah that's what I'm saying, it seems like he has changed his mind....

Guys got a Question!
For this question in Section B do you think there would be multiple answers?
This is the answer:
Begin
largestAge 0
For i 1 to 1000
IF ages(i) > largestAge then
largestAge ages(i)
END IF
EndFor
End
This was mine:
Begin
largestAge 0
For i 1 to 1000
IF ages(i) > ages(i+1)
ages(i) <-- largestAge
END IF
EndFor
End
Thanks guys appreciate any feedback
-
Begin
largestAge 0
For i 1 to 1000
IF ages(i) > ages(i+1)
ages(i) <-- largestAge
END IF
EndFor
End
what happens at i=1000? you compare ages(1000) to ages(1001), which doesnt exist
also i think you have your assignment the wrong way, shouldnt it be 'largestage<--ages(i)'?
you can desk check it yourself with a made up list of 5-10 ages and see if it works, but i dont think your logic is quite right unfortunately
-
sorry, i wrote it the wrong way on here, it was largestAge <-- ages(i)..
silverpixeli, do you think I could get a mark if this is the case?
-
sorry, i wrote it the wrong way on here, it was largestAge <-- ages(i)..
silverpixeli, do you think I could get a mark if this is the case?
an incorrect algorithm wont be able to score full marks, but everything except the condition was fine, so it may get 1 or 2 out of 3 marks
i dont have the marking guide but i'd say it'd be something like this;
1 mark for if statement,
1 for condition
1 for correct assignment with arrow correct direction
no idea if that's right though
-
Okay, thanks mate. Hoping to get 1 from that.. when i first saw it i had no idea what to do.
-
Guys Section C is done on IT VCE.
I know I have asked this a thousand times, so im sorry in advance, but im looking at like a 78-80/100 for the exam and my sacs average is like 94, am i still in contention for a 40 or a very low 40?
Thanks

*contender
Just because you scored highly on your sacs, it doesn't mean you'll will score highly holistically. The A+ cuttoff is fairly low, around mid 80s. I'm not sure if you'll get it or not.
-
Okay, thanks.
So would you say even a high A is not enough for a 40?
-
40 is top 8 percent, I think A+ is top 10
-
yeaaaah i so aint getting a 40 :(
Surely my SAC's will help? 50 percent of the final grade?
-

SACS are relative to your exam score, they don't automatically take a 50% chunk of your score :(
-
what do you mean? :)
-

what do you mean? :)
Not 100% sure but I'll give it a go.
I'm going to use an extreme example
---
Lets say you got 100% on all sacs, and get 1% on your exam.
Your not going to get that 50% worth of sac marks to your SS. That 50% will be scaled down.
Essentially what I'm saying is that even on the VCAA website it says Sacs are worth 50% of your mark, in reality Sac marks are no guarantee.
But dude don't worry, I checked VCEIT.com and I've made countless small stupid mistakes even though the exam was relatively easy. I'm pretty much in the same boat as you, looking at high 30's low 40's even though I'm rank 1. I believe I got 80% for the exam. What's done is done.
-
sac marks are moderated in light of your whole schools exam performance, so very basically they go down if your school doesent do as well on the exam (indicating that sacs are easier than at other schools) and they scale up if your school does better on the exam (indicating that the sacs were more difficult than other schools) and after all this, you get a sac mark that is fair in comparison to the rest of the state because sacs are not standardised, so they need to use exams (and a tiny bit of the gat, i think) to judge how you really went all year.
its a pretty complicated system when you get into the technicalities, but basically your 50% from sacs will be moderated a tad due to your cohorts exam performance. you dont get 'dragged down' by a weak cohort, though, your own performance has a lot more effect.
the thing is, everyone in the state is subject to this moderation and as a result its really wuite hard to tell what study score a certain exam/sac score will get you. I would stress less though, because firstly the exam is done and you should be spending your holidays free from vce, and secondly because youre looking at a high 30's/low 40's for the subject (you may have even done better than you think) (eg with A+ sacs and a low-mid A exam i got 39 in legal last year, after the exam i was expecting a 33-35 at best)
the point is, nobody can accurately guarantee you a study score, you just have to wait it out and see what happens, it may even end up better than you thought
