[Year 12 IT Apps] 2010 ITA examiners' report

[Mark KELLY]

*From the 2010 ITA Exam - Question 5B. * I have a belated complaint now that
I've seen the examiner's official answer in the assessment
report<http://www.vcaa.vic.edu.au/vcaa/vce/studies/infotech/it-applications/assessreports/2010/itapps_assessrep_10.pdf>
.

Can someone please point out if I'm wrong, but I think they've badly messed
up the answer, and kids will have unfairly lost up to 4 marks.

>From the PERT chart ...

They asked for a corresponding Gantt chart. Their solution was this:

It's obvious in the PERT that tasks A and B are *concurrent*.  *B is not
dependent on A*!
Yet in their Gantt, they've clearly shown task B as being dependent on A.
Then, they went on to leave out fact that that tasks E and D were also
dependent on task B through the dummy task.

I hate to think that my kids lost marks because of these errors by the
examiners.
It's too late to re-mark exams, but it really makes me worry that markers
can be given such dodgy official answers when grading papers.

*Grrrrr!
