    I thought that was pretty hard.

    Putting the game theory solution into a simplex tableau will cause problems and order book Dynamic programming questions are the hardest type.

    having a negative slack variable in the simplex question was very weird too.
    Grade boundary prediction Arsey?

    I think 71 for an A*

    Thats because it was that high one yesr and I felt this difficulty was very similar?

    I could write some answers up, but I don't have the Answer booklet.

    Understanding key principles and working on it. Enrichment maths like UKMT stuff.

    I am sure i said it is optimal, because there isn't any negative improvement indices.
    Dont worry, there are two ways of doing the second stepping stone; one will give negative(IF YOUR ROUTE IS IN THE TOP LEFT) and the other is positive(IF YOUR ROUTE IS ON THE BOTTOM RIGHT HENCE GIVING A SQUARE). That's why they didnt ask for the final cost because the answer can go both ways and its right as long as you are able to justify so.

    Do you know if the non optimal one got you -2 as the most negative improvement indice in something like B3 with I believe a -1 in one of the other cells aswell?

    From what I've heard, those figures seem to be correct.

    Do you think I'll get the mark for finding the correct route in flow augmentation , but i for some reason found it useful to back track the route before i wrote the final answer , i don't know how and why that helped me but somehow it did. So before i wrote the final answer, i wrote the route backwards as part of my working out, but after that i wrote my final answer (correct route) beneath that. But i dont know if i crossed out the previous working out in which i wrote the route backwards, but would i still get the mark if i wrote the correct route ?? It was only one mark

    Yes you will because the question asked to state the route only.

    Alright, so even if i didnt state or label that this is my final answer?
    E.g something like :
    Final answer: S ......... T

    Do you recall the total marks for each question?
    Will 40/75 get 55/100 UMS?

    Question 1 - 10 marks
    (a) - 2
    (b) - 3
    (c) - 3
    (d) - 2

    Question 2 - 8 marks
    (a) - 2
    (b) - 1
    (c) - 2
    (d) - 1
    (e) - 2

    Question 3 - 9 marks
    (a) - 8
    (b) - 1

    Question 4 - 9 Marks
    (a) - 1
    (b) - 5
    (c) - 1
    (d) - 2

    Question 5 - 12 marks
    (a) - 1
    (b) - 1
    (c) - 1
    (d) - 6
    (e) - 3

    Question 6 - 12 marks
    (a) - 2
    (b) - 7
    (c) - 3

    Question 7 - 15 marks
    (a) - 13
    (b) - 2

    When there is a table form dynamic programming question, boundaries don't go above 68 for 90 UMS. 40 would usually be 55-57 UMS. Do you need 55 for A* in AFM?

    Yep need 55 in D2 and 45 in S4(unsure about this aswell since it was relatively easier then normal). Hopefully I should be good.
