    omg sameI got 3.72 when I worked out the lower bound so managed to find four activities happening at the same time and said the minimum was 4 workersand I think the critical activities were four but I got 3 because I messed up part a
    Lots of people are saying there were 5 or even 6 critical so not sure You'll get method marks hopefully
    Really need to see some a mark scheme

    Hi,

    I had completed every D1 paper from 2010-2015, including the R papers and January papers achieving an A in every single one prior to this exam. And yet even I found this exam almost impossible to complete in the 90mins. It was an extremely hard paper.

    Everyone's comments seem fair on the grade boundaries. Considering last year 60 was an A, this years surely has to be around 57 for an A, otherwise Edexcel are smoking something.

    Lots of people seem to be debating the lower bound for the critical path analysis question. The answer is 5 (I am pretty confident it is). Using the cascade chart you have drawn you should have drawn a dashed line at day 12.5(I think), where you would see that 5 activities had to have been happening at the same time. Thus you need 5 workers. You should be aware that when they ask for the lower bound after you have drawn the cascade chart the examiner expects you to use the cascade chart to calculate it and not the lower bound formula.

    However I had no clue how to complete the scheduling diagram in part (d). I wasn't happy at all that Edexcel expected us to do a cascade chart and a scheduling diagram.

    Also the linear programming question is another area of debate. I am confident the objective line is 1.5y + x = C MAX. That was a particularly hard linear programming question compared to other years.

    I hope everyone did well.

    Again, how would edexcel combine the following 6 modules for 2 AS
    C1 C2 FP1 M1 S1 D1

    They will combine them in such a way as to maximise your grades, AS Maths first then AS FM, i.e. A C is considered as better than B B

    cheers. so I'm guessing they'd consider AA than (high)A and B, right ?

    I don't exactly remember the number but there were an extra critical activity ( no float) that couldn't have been done by the same W

    Would day 12 be sufficient?

    I'd say so - the timing will probably bring them down to around there.

    How could it have been 1.5y when it said it was 40% greater? Surely it should've been 1.4? It would've been 1.5 had it been 50% greater capacity.
