    If you've got no exams inbetween, I think you can do it, as long as you are getting enough sleep. Good luck!

    Anyone got the question paper? I wanted to get another look at question 8. Can someone tell me the equalities we had to plot?

    I'm so stupid and realised that when I was finding V in the linear programming question, because I found Y first I've wrote the co-ordinates the wrong way round. Will I only lose one mark though because I wrote X= and y= before the final answer of v=( , )

    I'm sure the lower bound of workers was 4

    For the objective function I wrote C=10x+15y without simplifying further, would that affect the number of marks I'd achieve

    The objective line was only 1 mark so if you did the rest correctly which you should have because your line will have the same gradient then you will lose only that 1 mark.

    For the algorithm question which of 122 and 0.5 should be X, I said 122 because it is an integer value, would this gain any of the marks? Student403 NotNotBatman

    Yes however this isn't the method you were supposed to use. You were supposed to use your cuntt chart to work it out, and if you did this you'd of found it was five.

    Ah.. that's one or two dropped from that then! I was pretty sure it was 82! I'll get marks for my method because I'm sure it's just one arc I've messed up on

    That question pissed me off. I thought it meant that 122 was the value of y and 0.5 is the value of t and you had to work out what x would be. I feel so dumb:ashamed2:

    Nope. A lot of people do activity networks in pencil. They'll mark it somehow don't worry
