hey arsey for q5) the bubble sort, your 7th pass is exactly the same as you 8th pass. is it necessary to show the 8th one? also what do you think of the grade boundaries? I'm thinking 67-68 for A.
4. yes, you will lose a mark if you do not have it

ALWAYS repeat the last pass, so you have two the same.

You might know it is in order, but you need to do a final pass, so that the algorithm does.

i wrote further passes produce no swaps so stop, will this do? also, in the jan 11 ms for 2c) it hasnt shown and extra pass
6. you should be fine with what you wrote, final (repeated) pass or a statement will do.

8. I think I drew ye graph wrong so I ended up with solution 70 as my coordinate, how many marks do you reckon I will drop for this? Will I get follow through marks when working out the maximum profit as I subbed In the coordinates I achieved

Thanks
9. Thank you so much! I thought I screwed this up (bad timing issue ) but it's not as bad as I thought from what I remember. You're a legend for posting all of these, seriously

no
11. Main reason for high grade boundaries= Arsey+Gibbo, giving great tips and increasing candidate performance!!! Any ideas on grade boundaries?
12. Somehow I calculated the float for D as 8, how many marks will I lose from drawing the cascade chart with that mistake?

.

i have just had an idea of how to improve our results

2 marks, 1 in c and 1 in d
15. Got everything right except wrote 2 12's instead of 1 and a 13 when doing my bubble sort, so will I just lose one for accuracy? And how will this affect the first fit decreasing 3 marker with this list?

I calculated the lower bound fine at least.
16. Arsey what do you reckon the grade boudaries are gonna be
17. not sure, 60+ for an A.

definitions are normally terribly answered, as will the dummy questions.

I think the postie question will be a bloodbath too.

LP was pretty kind.

Hi, is it necessary to give units of waste for the bin packing question? Thanks.
19. no

61,62 or high sixties like 67,68
21. For the second dummy , do you think it would be alright to put: Activities G and H must be uniquely represented in terms of end evernts
