so is it 26 or 27

I think these are mistakes:

Question 3 the route could be ABFDGEGHJ making it 26km

6) e) It is (7,7) as the inequality states x<8 so 8 isn't included

Question 7 are the critical activities C H J and L?

Critical path is wrong too i believe. Isnt it CHJL
Also, questions 7 (d), B has a float of 1 so isn't a crit activity whereas C is. Shouldn't it be on the top row instead of activity B? I thought you put all the crit activities for worker 1.

I'm pretty sure the y coordinate could have been 8. I put (7,8).
wait where are the model answers? sorry im special and cant find them.
where is the unofficial mark scheme ? I cant find it? Thanks

If I remember correctly (7, 8) was outside R because it doesn't satisfy one of the inequalities.
Lmao those who are hoping for low grade boundaries fear not, even Arsey made mistakes

question 6 on the integer solutions, since its x<8 and its a strict inequality, it cannot equal 8?


oh ffs
Thank god Djikstra is right.. think I lost 6 marks + any other stupid mistakes.

for the question asking how we got our route, I used words to explain how I did it followed by an eagle. Will I get marks??!!

B isn't a critical activity is it? It's 7 and the node says 8.
It's C that's critical not B

How can the max value be (8,8) when the boundary for x<8 was a strict inequality?

edit: someone already asked this. My bad.
