I think this year it'll probably be 60, 66 and 72 for an A, 90% and 100% respectively. I thought that the paper was slightly harder than usual as most people struggle with linear programming.

Sorry i dont understand what that means, does it mean. 60/75 for a C 66/75 for a B and 72/75 for an A or?

60/75 for an A
66/75 for 90
72/75 for 100%

Well, that's what they think anyway.

I reckon they could be lower than that because this was undoubtedly the trickiest paper since the new spec, i think it was june 09 or maybe june 10 where an A was 61, which was actually an easy paper...

it was kinda easy paper
so i m afraid the grade boundary for A will be high
(my minimum mistakes-7 marks according to the posted mark scheme)

I'm not sure how you can say it was an easy paper whilst making mistakes that lost you 7 marks?

how many people actually finished this exam comfortably and in comparison to previous exams it was not very easy

i meant to say maximum

Just need a general consensus does everyone agree this was that toughest paper of the lot since the new spec started and do you guys think it is likely the grade boundary will be below 64-65?

I think that it was definitely the longest paper for a while, and the 3 marker on the cascade chart workers was quite wordy. The last question would've caused problems with most people as it says in an examiners' report that linear programming causes the most problems.

Hello, for question 3 the linear question, how do you know the constrain for 6x+5y=60 is 6x+5y<or= 60 rather than 6x+5y<60? because they didn't draw dotted line or anything else to distinguish between it.
