1. B
2. C
3. A
4. B
5. D
6. E (i think VCAA made a mistake here, becuase no direction for the dummy was specified, therefore i didnt know 'which way to go'.... i came to my answer by using the path CDFKL which ends up with 18hrs as the critical path, and activity L with EST:16)
7. C
8. B
9. B (FUCKING GOT THIS WRONG FORGOT TO COUNT THE 1 EXTRA LINE IN THE SECOND COMPETITION AGRHSJFESTFLEWGFSJDHGJGD :evil: )

Nick:
LOL by the looks of it I totally screwed networks..thats what you get for not studying I suppose.

Lyonzy:
Hey, (first post lol!)
In question 9, i got B because i used the formula edges=(vertices(vertices-1))/2 for connected graphs.There was 10 edges originally, but in 2008 there'll be 21, making a difference of 11.

I think everyone'll get the mark for 6, that happened in like 2006 or 2005 or something.

ok 1) isn't B, because you can move one line to make it planar, the answer should b E, it's soooo not a tree
i stuffed up Q5, that was a dodgy question if you r ead it properly
your right with the dummy aspect, the VCAA made a booboo, which made it harder to try and get the right answer, so i think i accidentally did 15, damnit
Q8) i got A, two step dominance, Team A got 7 all up, and Team B got 6, therefore, the answer is A

and then i ran out of time, so i did the "when in doubt choose C" rule, and clearly got it wrong

kjg:
i meant question 8 i got A
