Hi Frank. Yes, question 5a about the critical path is fine. In fact it didn't depend on the Gantt chart at all. <br><br>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).<br>
<br>It's easy enough to find mistakes in the questions asked in an exam; the problem is that if the markers' <i>solution</i> is wrong, we can't find out until the assessment report is released and it's far too late to do any good.<br>

assessment report</a>.</p><div><div></div><div class="h5"><br>
<br>
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.<br>
<br>
>From the PERT chart ...<br>
<img src="" alt="b5.jpg" title="b5.jpg" border="0" height="245" width="541"><br>
<br>
They asked for a corresponding Gantt chart. Their solution was this:<br>
<br>
<img src="" alt="assrep-gantt-solution.gif" title="assrep-gantt-solution.gif" border="0" height="157" width="504"><br clear="all">
<br>
It's obvious in the PERT that tasks A and B are <b><span style="font-weight:bold">concurrent</span></b>.
<b><span style="font-weight:bold">B is not dependent on A</span></b>! <br>
Yet in their Gantt, they've clearly shown task B as being dependent on A.<br>
Then, they went on to leave out fact that that tasks E and D were also dependent on task B through the dummy task.<br>
<br>
I hate to think that my kids lost marks because of these errors by the examiners.
<br>
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.<br>
