[Year 12 IT Apps] 2010 ITA examiners' report

[Mark KELLY]

Hi Frank.  Yes, question 5a about the critical path is fine. In fact it
didn't depend on the Gantt chart at all.

It's the 4 marks for the Gantt chart in Q5b that kids may have lost. I don't
know how many marks were lost if my kids started task B in day 1 and
correctly added dependency arrows to D and E from the dummy task (as they
probably probably would have done).

It's easy enough to find mistakes in the questions asked in an exam; the
problem is that if the markers' *solution* is wrong, we can't find out until
the assessment report is released and it's far too late to do any good.
