# Edexcel D1 - 17th June, 2016 [Exam discussion] watch

Yeah thats very true but if you notice when they changed the spec (2009) boundaries started to range from 59-67
Random Q, but could you rememebr the first dummy we had to draw on the 2nd Q
2. Sorry to break it to you but odd/even is only a definition which can be applied to integer values, so it would never be odd or even, hence stuck in a cycle of does x = 0? no, x = x/2

it won't tend to negatives because you'll never get to the point where it gets to x = x-1, you'll be stuck in a loop of x/2, which is inferred by the necessity of an integer value for X
Correct

(Original post by Pablo Picasso)
If you inserted .5, then it isn't odd, nor = 0 either, so it'll -1 everytime (?)
No. You only -1 when you answer yes to "Is it odd?". If you answer no to both, you keep halving x.

A to D or F i think. Cant remember exactly

46 for an A (June 03) and a lot in the low fifties.
And in June 2004.

Wow, they ARE low, aren't they?

Yeah - I cannot see it being any higher than 56, I'd say either 55/56 for an A, I don't really envision anything lower than that either to be honest..

The grade boundaries usually go in intervals of 6, don't they - which would make it 61-62 for 90 UMS, and 67-68 for 100 UMS; is that right? WOW - get in there! I really didn't feel all that confident coming out of it - what with already knowing that I got the schedule wrong, and not having any time to check my activity network. But, actually, with those sort of grade boundaries, D1 will probably end up being one of my strongest modules this year!

Don't take my word for it!!

I'm just basing it off of how it seems the majority found the timings and questions etc.

I know - but, it's definitely much more reassuring that everyone seems to think the same thing. Thanks for your predictions, anyway!
11. Hey does anyone have model answers ??
12. Hey, at least they didn't ask us to explain the uses of those three dummies - that would have taken even longer!
13. Was the questionning

1. Matching
2. Preceedence table
3. Algorithm
4. Djik
5. Flow Chart
6. Gantt chart & co
7. Program

I wish! If only Edexcel hadn't so ruthlessly and gruesomely murdered Arsey like that...

No.

1) Matching
2) Precedence Table
3) Bin Packing/Quick Sort
4) Algorithm (Flow Chart)
5) Dijkstras
6) Route Inspection
7) Gantt/Scheduling
8) Linear Programming
16. Doesnt anyone have a copy of the paper?!!!!!

There were eight questions, so it must have been something like this:

1. Matchings
2. Activity network
3. Quick sort
4. Dijkstra's algorithm
5. Flow-chart
6. Route inspection
7. Critical path analysis
8. Linear programming

(*The first three and last two were definitely in that order, but I'm not entirely sure about the order of questions 4-6...)
18. (Original post by iMacJack)
No.

1) Matching
2) Precedence Table
3) Bin Packing/Quick Sort
4) Algorithm (Flow Chart)
5) Dijkstras
6) Route Inspection
7) Gantt/Scheduling
8) Linear Programming
That's probably the right order!
19. Does anyone know the breakdown for the linear programme question? Or just the marks breakdown in general. Would be helpful for everyone
20. (Original post by mupsman2312)
That's probably the right order!
Yeah I'm sure about them all apart from Dijkstras and Algorithms, they may have been the other way around, not sure
