    I thought it was the delux ones which had 50%more capacity

    So c= 1.5Y+x
    yh thats what i put originally but when you put into the equation, your y values should be 1.5 times bigger than x values e.g. make c=9 and you'll see. it makes sense

    does anyone reckon that 62 is an A? and also if you get the values of w x y z whatever wrong (one of them) would you get follow through marks for your Gantt chart and scheduling but lose like 1 on each part?

    Did you have to simplify 20x + 65y =< 520?

    Also I got C=2x+3y. Would this not be right because we aren't given a value for capacity, only relative capacity?
    Put that down as well. Should be right, there was no reason not to put that down

    Has it been confirmed that 1.5y + x is (3y + 2x) correct?

    Can anyone here please tell me if I will get follow through marks for putting 1.5x + y (3x + 2y)?

    I'm sorry, but charting and scheduling 14 activities, over half of the bloody alphabet, was a complete waste of our time and not a test of our mathematical ability.

    Other than that question, the paper was very fair.

    As last year's paper was easier, I would guess around 57 for an A. Cannot be much higher than that

    For the y value of V I got 280/59, anyone could confirm or correct me ?
    That's exactly what I and most people I know got!!

    Finished every Past Paper with a good 10/15 + to spare. This one, the CPA and Linear Programming both were time consuming, to add onto the painful Route Inspection and Algorithm. Way too long. Not impressed with Edexcel - not testing mathematical ability but speed.

    In the end, skipped over the scheduling (just filled out the critical path basically) and just about finished the Linear Programming although didn't test all the vertices for the last part.

    If you look at the grade boundaries from edexcel D1 the mark for an A is generally between 60-70 marks. Edexcell have also posted on their website that their grade boundaries are going up across the board, in C1, C2. FP1 ec. I may still be wrong but edecel have been being a bit harsher than usual recently.
    show me where they've said that they're raising the boundaries then

    Not sure bout the gradeyes you would get your ft marks but lose A marks

    so the paper was bad, i didn't finish. Id say i skipped the last third of q7 and the last half of q8. Luckily a C on this and a decent ums on c3 and c4 should still see me getting an A overall. But idk if i even got a C on this

    For the linear programming i used point testing and found that the highest capacity was when x=12 and y=3 , using C=2x+3y. Then i put it into 20x + 65y to get the cost as £435. (11,4) and (10,5) had lower total capacity so i dont think they are correct if anyone used them. For the algorithm one why did people do 122x0.5 i didnt see y being 0.5 anywhere on the question so i used the value of y in the table which was 5 right? then did 122x5 to get 610, is this correct.
    the two input values were 122 and 0.5? therefore one of them was x and one of them was y

    last year 58/75 was an A, it might be around there this year if not probs a little lower

    I'm just glad this is over now. I hated this module more than anything :|

    Thank goodness my college put D1 as the A2 module instead of AS...
