Thoughts on exam?

Thanks 

Seems like he isn't quite happy with Q18 and Q19. I do hope VCAA will give free marks to those who answered after actually carefully examining the dodgy questions, as the same thing has happened in previous years.

Well, after reading Mark's explanation, D does seems like the most plausible answer. You can enter anything into the required field as opposed to a dropbox where you can select acceptable options.

Q18 is definitely C. Data has to be removed safely, not just deleted as it can be recovered. You must overwrite or damage the HDD.

Latern, true, it's so hard to choose from them though. It doesn't seem like it 'validates' data though. Idk, we'll wait and see :p

I'd probably disagree with his answer to question 1. It asks for a type of online community. Collaboration and knowledge-sharing are purposes of almost any online community, I can't imagine an online community where "knowledge" isn't being shared. We can rule out A since the website describes doesn't seem to be centred around socialising. But the website does seem to be centred around a project, which is the major thing that the question stem describes, so I don't think the reasoning for excluding C just because those online communities aren't "usually for outsiders" is valid.

What convinces me that C, project-based is probably the answer that VCAA is looking for is this study design dot point: "types and purposes of online communities including social, work-based, project/interest-based that support the purposes of collaboration, knowledge sharing and collective identity".

I read that as "types and purposes of online communities including social, work-based, project/interest-based [online communities] that
support the purposes of collaboration, knowledge sharing and collective identity" i.e. that the types of online communities are the first three, and the purposes are the latter three.

what was the answer for question 2 multiple choice,,,, was it project-based or knowledge-sharing?

go an see the answers to the exam  on this link http://vceit.com/p/postmortem-2013i.htm

What did people do for question 12?
And what sorts of scores did people get for multiple choice? :)

[Ruzzah112]

Well fuck, looking at Mark Kelly's response, I probably got 14/20 for multiple choice ;(

[skadoosh]

I got 18/20.

I got Q1 wrong (great way to start off checking my answers ) and Q10 wrong.

I did C for Q1. I really think that is more of a project/interest based community rather than a knowledge-sharing one. Anyone else agree with me on that or I'm alone?

I'm so annoyed at myself for Q10, I finished early so I figured I might as well look over my answers and ended up changing 10 from B (right) to A (wrong).

Note to self, stick to your gut 

Anxious to see results for Section B as I know I didn't do too well.

MK has posted solutions for section B.

I disagree with his assumption for the normalisation question:

This solution assumes that each captain only has one boat, since the question says that "Each boat has a captain". If not, the schema would get a lot messier!

VCAA have not specified whether a captain can be the captain of more than one boat. And the answer to this question is extremely important.

Damnit.. had backup for 1b.. but I crossed it out and recommended a password for that area of the website.. oh well..

Also, MK is right about the SS/RDBMS question. There is no 'trend' we were only supplied with the sales for that time. Also.. would a pie graph be suitable? I didn't choose a bar graph.

[hayleyyy22]

Who knows, I did a line graph haha
