I found some of the questions quite difficult! UGH!

I found some of the questions quite difficult! UGH!
Im with you, it was way longer than last years just got it finished. The algorithm question was fair hard, didnt even fill in that table. Dam was really hopeing for a 40 in this subject.

Was the course much different from last year's? I did Information Systems last year, and am wondering how different the IT: Software Development course is now.

You might still be able to get a 40 :)
-
It seems as though the hardware aspect of the previous cource isnt really part of the SD course. Their wasnt many questions on Hardware at all. Theres 3 parts now, A - Mult Choice B - Short C - Case study
Hummm, looking on last years theirs still some questions that were similar 2 today's exam. I guess its more to do with the software side of IT now? or mabey they just didnt examine it this year.
-
I think they do more software side of things now. Hence software development. Anyway what score on the exam do you think everyone will need to get 40 raw.
-
There was that hertz question, like only one question on networking (:() and everything on PDAs/laptops/phones. I think they're just going to tie it in with the design specifications of the software a lot more, that's all.
Woohoo!
I think. Haha.
I got it all finished with 20-30min to spare... might have rushed some questions and I felt like I was repeating myself on a few things. Maybe I was, maybe I was meant to? I wouldn't know - I spent most of that spare time trying to work out that algorithm :?. Looking back I probably would have been better off looking over everything else. I know I messed up that data type question too - integer, 1D array, 2D array, yeah? That's not what I wrote for the latter two, but it makes sense. Don't think it'll be another 49 here, unless I somehow managed to get everything else perfectly... :roll:.
A 40's probably still quite possible dude. You could've got ~42 last year dropping up to 15 marks in the exam, and you guys seem to think it was harder, which could mean even more lee-way, so it's not all bad!
-
I found the exam really hard aswell, I know I screwed up two questions in multiple choice, They were so obvious too, when I looked at them a second time (I got a blank copy of exam, after exam).
What was everyones errors in the algorithm? I said that "Product_Recipes(Product_ID, Ingredient_ID)" needed to be "Product_Recipes(Ingredient_ID, Product_ID)"
-
Did you guys manage to find the 'logic error'? In the picture which had something about incoming message
-

I just said it was the fact that a message would be rejected, which it should be a "remind me later button" or sumthing similar. What you have?

I just said that it didn't have any info about sender or subject and to put more info on there like 'message from fred: 17 more loaves needed' or something. Did u guys just say 0 for the second two actual results in the test table?

I said 0, but some other people said N.A. Because it wouldn't output any data, because it was looking in an invalid field.
And for that message, I wrote the logic error was it didn't say who the sender was.
-
Yeah I said that there was no indication of WHY he'd want to accept or reject the message as he was not informed of the contents - solution: include details of subject and sender of the message within the box.
-
well i got that wrong lol
-
Haha I stared at it for a while, don't worry.
My friend read 'HAS' received a message and initially wrote something along the lines of he can't reject it because he's already got it. Fortunately he changed his answer to something more serious bahaha.

I was thinking about writing that, then realised it was a crappy answer. :D
What was everyones chosen PDA? I did Strawberry.

What was everyones chosen PDA? I did Strawberry.
I picked the Peach, but now i think about it, it was most likely a bad choice.
I agree the algorithm was total bull! i couldn't comprehend past the first repeat until -loop. so i picked my misstake in that section as
" until Ingredient_ID > Num_ordered " (i think that was it)
i said it should of had an "=" sign for some pointless reason.
but the way i see it they give us junk, we give them more junk. (worded slightly different)!!!

Well, it had to be peach or strawberry, as they were the only two with internet (Watermelon had bluetooth, which isnt helpful for sending data remotely)
I chose strawberry over Peach for the QWERTY keyboard, Extra cell in the battery, bigger screen and faster processor.

B. accounts\invoices\
C. root\accounts\invoices\*
D. root\accounts\invoices\b 1245\
The others are just silly.
I did C too, but now I'm 99% sure it is D, this is because it looks like a sequential access structure now.

Lol 60 GB.
That exam wasn't as easy as previous years. Hopefully it'll be one of those years where the cut off of A+ is low like around 70%. I got the whole algorithm question wrong!! >< Well I attempted the first part lol. Everything is okay.
-
I only dropped one mark on section B. Stupid hybrid networks. Who needs to learn about them anyway!?!?!?!

I doubt that. I'm guessing an A will start from around 82-85%?
I only dropped one mark on section B. Stupid hybrid networks. Who needs to learn about them anyway!?!?!?!
Section B was really easy, Well, I thought so.
http://www.mckinnonsc.vic.edu.au/vceit/postmortems/2007sd/index.htm#b
With question three, mine was identical to his. If you read his comment it said "A bit simple, if you ask me. Unless I've missed something!" That exact thought was going through my head while I was doing it.
Any opinions on it?

Yeh I got D....
-
I got 18/20 For Multiple choice. Lol I can't believe I made silly mistakes. And I got 20/20 For Section B. And no wrong so far for Section C. Lol that's cause the algorithm isn't uploaded yet :D
I doubt that. I'm guessing an A will start from around 82-85%?
I don't know about 82-85% for an A, last year the cut off for an A+ wass 85%, and the exam was easier this year.
-
It can't be D. They have different file names!
-
I don't know about 82-85% for an A, last year the cut off for an A+ wass 85%, and the exam was easier this year.
I thought the cut for A was 85% last year :P Meh, its all the same. Im in year 11 and don't really know how the system works yet.
19/20 according to that web site, but Im 99% sure about that question being D, so I'd say 18/20. 100% for section B, and I'm confidant about section C.
:)

oh shit it does 2

Lol I don't get how it could be D. The b1245 is completely different to b4532. It must have been C

I hope it is C, cause thats what I chose.
You know the difference between random access and sequential? Well, look at the stucture of the diagram.
(http://www.mckinnonsc.vic.edu.au/vceit/postmortems/2007sd/a05.gif)
It implies that to access b4532, b1245 has to be read first.
I don't like the notation root\accounts\invoices\b1245\ but I can understand how it could be that. Also root\accounts\invoices\ isn't a full path, IMO.
Its a stupid question.

It would still be wrong. The answer. The file name in the diagram was b1245 but the one in the question was b 1245. Notice the space!

I've got the question book right next to me, there is no space. Don't ask me why there is on the web site.

Oh yes I see where your coming from. Damn I didn't think about it that way. Hmmm, since they said the full path I thought it referred to as the file's actual directory on the hard disk. But yes I think you might be right. I haven't see a tricky question like this from VCAA.
-

Like I said, I hope I'm wrong because I chose C too, but its more logical that D is correct, with the layout of the diagram.
-
Found it relatively easy. Except the algorithm question and the new email question.
-
Strawberry too... it makes more sense. On a screen size that big it would be hard to work with a touch screen for that type of data input.
If it was D, it should have specified that the file access was sequential. How do you think they would havewritten it if it was random access? There's no other way they could have presented the folder tree to indicate one over the other. I think I remember a question similar to this in the old IPM exams, and back then it was simply a case of file directories. I don't see why it would be any different this time.
-
BAHAHA Q8 MC I did floating point instead of string - I didn't see the T.
Lol I agree with him for Q14... what was the point?
And Q3 as well... some of these questions were so simple they made me sit there for ages wondering if I'd missed a point. Anyone else?
I'm glad he put down customers too - that was a bit iffy. Essentially the system interacts directly with the drivers, and then they should have a process leading to the customer entity, but seeing as the drivers are just passing the information onto the customer I figured they could have been seen as part of the system...?
2c - didn't even think of his answer. I think I did recipe ingredients - number made should be quantities required... argh.
I never thought I'd see the day I'd have to write 'cake is not data' on a VCE exam :wink:.

According to his answers, I can only see a total of 8 marks lost. But I'm estimating about 9-14 marks lost, because I don't agree with all his answers.
Expecially Section C, Q2, part A. It has to be DFD C, not A. The data flow of ingredients getting low is just a dead end. It goes into the process, but nothing is done with the data. Doesn't make sense. Data going into a process, must be manipulated in one way, or another.
And yes. Section B, Q3 I was just sitting there thinking "Have I missed something, this is too easy"
Strawberry too... it makes more sense. On a screen size that big it would be hard to work with a touch screen for that type of data input.

I think I remember a question similar to this in the old IPM exams, and back then it was simply a case of file directories. I don't see why it would be any different this time.
So your saying it was C? I was looking again today, and thinking it has to be C again. If it was sequential it would be represented one after the other, instead of branched off like it is.
So I hope its C, cause thats what I chose. Honestly, I'm just not sure about that question.
-
Yeah I reckon it's C.
Hmm, I went A with that DFD so I hope he's right for my sake, but it's a good point you're making. It does say MOST CORRECT so that'd indicate that none of them are actually complete... that's actually one helluva ambiguous q!
My thinking was that 'ingredients getting low' was combined with the 'customer orders' to create the 'items to be baked' flow. Depending on the meaning of 'quantity required' in the data dictionary in the next question (which shouldn't need to be looked at to answer this q...) that might or might not make sense.
It's not clear whether 'baking requirements' also refers specifically to the requirements of new stock, or just the customer orders themselves. If it's not, it shouldn't even be there and you'd be right.
Urgh, I dunno, what a frustrating question!

I don't see how ingredients getting low have anything to do with items to be baked. You would think when ingredients are getting low, more should be ordered.
There was alot missing from those DFD's, and I honestly don't know anymore. I just don't see where the data flow "Ingredients getting low" is going.
Its going to be really interesting to read the examiners report, when its released.
Also,
Section C, Q14
Question 14
As well as training, Michael suggests to Kayla that she should produce user documentation for the drivers to use while making deliveries. Kayla has several ideas.
Option 1 - Burn a video onto DVD so they can see what to do
Option 2 - Put help onto Flip Flop's new website
Option 3 - Print a quick guide that covers basic use of the software onto a card that can be put into their pocket
Option 4 - Electronic help manual with a search facility stored on the PDA
State which option is the best in this case and justify your answer. 4 marks 9 lines
I chose option 3.
I don't see how it could be option 2, even though the PDA's have wireless internet, the most effective way would be option 3.
Other thoughts on this question?

Other thoughts on this question?
I said option 4 and justified that it was easier for the Drivers to have it in electronic file because they won't lose it and they can easily search for topics that they need. The documentation can also be easily updated and easily distributed through the Driver's PDAs, etc.
-
Option 4 too. If they have their PDA, they'll have the help files. They can also add as much detail as they want because the search function can a llow for a detailed or less-detailed response as required.
Opt 1: Obviously not - no DVD drive.
Opt 2: Sure there's Internet connectivity, but they're not always going to be in range and the costs of access/dl's could be an issue, maybe... depends on the setup.
Opt 3: Pocket - how easy would that be to lose, leave at home, or accidentally put in the wash?
