I didn't do assignment 2, until now, but noticed that question 2(f) was asking for "free slack (float)", but the model answer dealt with total float. As an example if you compare the answer to that of 2(c) free float for D is 0 and not 3 which is the toal float.
Anyone else pick this up? Any feedback from lecturers in the marked assignments?
It is not uncommon to have these errors. You will find that often the questions are used year after year and some minor things are changed. But they forget to change the answers. So last year they asked for total float, and this year free float. And they used last year's answer this year.
