[Informatics] VCAA Practice Exam - Sect. C, Q1, Sect. B, Q4.

[Lydall, Quentin C]

Hi Ashley and Ben,
I agree it is a strange question because as a software developer I never saw that type of diagram and wonder where it came from. But I also agree that the B path is followed if something was missed by the user, some other validation failed, or the user chose to edit their entry before proceding.
The Gantt chart question (C Q9) was also a bit strange because overwriting the original time line is clumsy, though it was a useful lesson in exam technique for my students.
Mark Kelly has written comments on the answers which are useful, though I disagree that a milestone (Task D) would take up a whole day, and Sect C 2 B ii should include Date_Attending. Google VCE Informatics and you will find his website.
Thanks, Mark, BTW.
Cheers,
Quentin Lydall

Ben,
My take was that the user had failed to supply all the required data and so could not move on until they had done so.

Hello All,

Looking for some feedback on the VCAA Inforamtics Sample exam. As there is no sample answers I'm just unsure on some questions as to what the best response would be.

Section C - Q1A -
State the condition(s) that would cause the paths labelled B to be followed.

Is this as simple as - The user is able to return to the beginning of the purchasing process at the end (display total cost) if they decide they wish to edit their order.

I feel somewhat dumb that this question is troubling me the most as it's only 1 mark and I find the rest of the exam somewhat easy.

Section B - Q4 - key words here to me are efficient and accurately. She is trying to put information from 300 photos into a spreadsheet/database to help her identify how many of each different house type there was in what decade. I was thinking along the lines of developing a spreadsheet/access with the appropriate fields/rows (decade & house type) and then "codifying" each the photo into the appropriate category - followed by using a COUNTIF or a Query (if using Access) to generate a count of different types of houses as per Q4b. Then i thought, is this efficient? It seems like it would take a long time to do this - but how else do you convert visual data, into text quickly?? What are your thoughts on this?

Maybe i'm having a "brain fart" moment and missing something more obvious here?

Looking forward to your feedback.
Cheers :)
