4 bins, and i think the 3rd was full
7. I'm pretty certain the finishing point was H because BC and CE had to be the repeated arcs and they totalled the shortest length (384 + 35 = 419)

I got 459 for my length on the first critical path analysis question
12. Can we just take a minute to talk about how retarded all the networks looked? Jesus Christ edexcel. I think it was the question where the answer was 48.

Do you remember how many marks the last part to the last question was?? I missed it out due to time X
I think it was 2 marks, one for the number of x and y, and one for the total cost

Yeah that wiggly arcs were totally pointless, it was as if Edexcel was toying with us

I got a 65 as well, not sure if it's right as everyone seems to have got 75
16. i got 12 for w because i did 17-5
and i got 21 for one of the other letters so basically i got 3 critical activities. a,d and k
i got 460 for the chinese postman too
and i got 11 and 4 for the last question with a total of £32
for question 4b could you say that 1/2 can't be even so x=122?
for question 8a could you simplify it from 20x + 65y = 520 to 4x + 13y = 104?
instead of 9 and 4, i got 10 and 4
17. Drew my diagrams in pencil!!! Can anyone let me know if that matters at all please??
18. For the optimal line, do you strictly have to use simutaneous equations could you have simply took the points graphically where they intersected? Help.

It won't scan, so you would not obtain any marks for that question
