[Year 12 IT Apps] 2010 ITA examiners' report

[Dickeson, Sharon L]

I agree. Task b can start anytime during task a or at the end as task b duration is two days. Just needs to finish by the end of task c. There is three days slack time.

Examiners should have accepted several answers including this one.

Hi Mark
Technically the only problem with the Gant chart is that Task B and A would have begun @ the same time but then there would have been 3 days slack time while A and then C were completed so the answers would still be correct even though the chart has errors.

Yet another awesome question from the Examiners well almost?

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.

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!
