1. (Original post by The 5th Sense)
I got 63 and I know others who got 65 and 60 lmao
Oh really hahaha that was the only one I wasn't sure on really
2. I got 61 too
3. I got 63 for time for 2 workers
Hungarian algorithm I got 61
Simplex I got 36
Game theory I got p=3/5 and p=9/10 (for the 2 different people)
28100 for the maximum question
Max flow = 32 on network flows

4. Right these are my answers, shoot me down

1. Time is 58, critical path can't remember, float time 2, min completion time 2 then allocate the critical path to 1 worker and the other activities to the other.

2. Got 3 allocations then min cost is 61

4. P as 36

5. 281000

6 value of cut 45, max flow 32

Get in the fella
6. I got 61 for min time. Anyone else? How many marks would I lose if it's wrong? Need full marks in D2 to get a A* They said you need overall 270ums in two of s2 m2 d2 and in one of fp2 and fp3 to get an a* for AQA. Is it true?!

I got 61 and no it could be d2 m2 s2
9. Was the value of the cut 45?
10. Hi everyone - there's been an unofficial markscheme started for this exam here

You got the same as me apart from the time for the workers, however it was only 3 marks so I am not too worried if I drop them

i got 63 big ones
13. What we thinking for GB?

100 - 73
90- 68
80- 62

Safe then!cheers!
15. Right. I've got a bit of a dilemma.
I wrote all my tables for the Simplex question in pencil (to be able to correct mistakes) with the intention of going over it in pen afterwards. I never got around to it.
Will I lose all these marks?
16. Overall consensus - hard or easy?

Overall consensus - hard or easy?
I thought it was hard in the sense that lots of questions weren't split into individual parts (e.g. Hungarian) and there were very few 'show that' questions. However, I found it pretty easy ahha

Overall consensus - hard or easy?
Closer to easy than hard, i thought it was cheeky that you had to spot the domination in the game theory question, usually there would be a two marker like "explain why X would never play game A", Network flow question was easy, the resource leveling question i don't think i got and the rest of the questions were standard past papers, so a really good paper imo
19. I put £281 instead of £281000 I forgot to see the units for the dynamic programming question. Will I still get the marks?

Yeah I did exactly that with that dynamic programming question.
