    For Question 19, on the markscheme, it says (4.4) and (-0.4) but the interval goes up by 1, so won't one square equal 0.2 units and make the answers (4.8) and (-0.8)? Just wondering..
    And can anyone confirm if Question 2(b) is right because I can't seem to get it the way Mr. K did..

    Everything was going so nice and smoothly. And then Edexcel Maths had to happen. I feel so **** now! How am I meant to get prepared for my next exam when I'm experiencing post-maths exam depression!
    I mean it was ok-ish, but then when you realise you made stupid STUPID mistakes and you're heart sinks...
    I'm a failure.
    Anyways, on the plus side we have a whole fresh set of 100 marks to gain. If all goes well, I shall be getting that C/B grade. That's all I want, that's all I need.

    For the first question, it was rotate clockwise 90*, I vividly remember it. However, I messed up on the reflection of x=-1 and reflected it on the other line, god dammit.

    This is the completed mark scheme for the 26/05/2016 mathematics non-calculator paper.

    If there are any mistakes, please tell me.

    Reps would be appreciated, but are not necessary.
    Spoiler:
    Show
    Question 1. What is the volume of the prism? (2 marks)

    Area of face = 30cm²
    Length of prism = 25cm.

    30cm² x 25cm = 750cm³




    Question 2a. Reflect shape in line X = -1 (2 marks)

    Attachment 538919

    Accept correct reflection.

    Question 2b. Rotate shape 90° anticlockwise. (2 marks)

    Accept correct rotation.

    Attachment 538937




    Question 3. What is wrong with the questionnaire? Give two reasons. (2 marks)
    Attachment 538813
    'Too vague (i.e. not 1-2, 3-4 etc.)' and 'no time frame (i.e. not per week, per month, etc.)' are accepted.

    Create a better survey for him to use. (2 marks)

    Why is his maths class not a good sample? (1 mark)

    'Too small' and 'may be biased' are accepted,




    Question 4. Simplify.
    P2 x P5 = P7 (1 mark)

    G6 ÷ G4 = G2 (1 mark)

    (K3)2 = K6 (1 mark)

    Expand and simplify 3(m+4) - 2(m+1)

    10-5m

    Factorise n2 - 7n

    n(n-7)




    Question 5. Estimate 892 ÷ 18.9 (2 marks)
    Round to 1 significant figure

    900 ÷ 20 = 45




    Question 6. A teacher is picked at random. 3/5 chance they are female. 36 are males. (3 marks)
    How many teachers are there altogether?

    2/5 of teachers are male. 36 are male.

    2/5 of total = 36
    2 x 18 = 36
    18 x 2 = 90.
    Answer is 90 teachers.




    Question 7. Can the floor be varnished with 3 tins of 2.5 litre varnish and it is 5 m2 per litre. (5 marks)
    Attachment 538829

    2.5 m x 6 m = 15 m2
    2.5 m x 6 m = 15cm2


    10 m - (2.5 m - 2.5 m) = 5 m
    6 m - 2 m = 4 m

    5 m x 4 m = 20 m2

    15 m2 + 15 m2 + 20 m2 = 50 m2

    5 m2 per litre, 50 m2 ÷ 5 m2 = 10 litres

    2.5 litres per tin, 3 tins, 3 x 2.5 = 7.5 litres.

    Not enough, 7.5 litres is less than 10 litres.

    Answer is 'not enough' with evidence.




    Question 8. Spinner, spins 300 times.Answer is 60.




    Question 9. 5 envelopes in small, 20 in large. What is total?

    T = 5x + 20y



    Question 10. Point is the midpoint. Where is the other end?Answer is (-3, -2)




    Question 11. How many females visited the art gallery?66 students went on the trip.Males - Bowling - 4Females - Bowling - 6Total - Bowling - 10Males - Art Gallery - 9Females - Art Gallery - 11Total - Art Gallery - 20Males - Skating - 10Females - Skating - 26Total - Skating - 36Males - Total - 23Females - Total - 43People - Total - 66Answer is 11 females.





    Question 12.Attachment 538769Area of square = 10cm x 10cm = 100 cm²Area of circle = π5² = 25π cm²Area of shaded = Area of square - Area of circle = 100 cm² - 25π cm² = 100 - 25π cm²





    Question 13. What percent of his total spending is his rent now?
    Answer is 36%.




    Question 14. Bisector of an angle
    Attachment 538913

    Correct perpendicular bisector of line
    Attachment 538961




    Question 15.

    Compare median, interquartile range and range.


    200 x 25% = 50
    200 - 50 = 150

    Last part, answer was 150.




    Question 16. (3.5 x 106) ÷ (5 x 10-3)

    7x108




    Question 17a. Solve 3x - 5 < 16x < 7

    Question 17b. Solve (11-w) ÷ 4 = 1 + w
    w = 7 ÷ 5




    Question 18(?).7/52 4/54/5





    Question 19.

    x = -0.4 or x = 4.4
    x = -1.1 or x = 5.1
    x = -1.7 or x = 4.7




    Question 20. What is the angle?Angles in a triangle add up to 180°, base angles in an isosceles are equal.180° - 48° - 48° = 84°Angle at centre is twice angle at circumference.84° ÷ 2 = 42°Angles in a triangle add up to 180°, base angles in an isosceles are equal.(180° - 42°) ÷ 2 = 69°Answer is 69°.




    Question 21. What is the chance of the match being cancelled when it does not rain?
    Attachment 538811
    0.8 x 0.05

    Answer is 0.04.




    Question 22. Solve X² = 4(X-3)²X² = 4[(X - 3)(X - 3)]X² = 4[X² - 3X - 3X+ 9]X² = 4[X² - 6X + 9]X² = 4X² - 24X + 360 = 4X² - X² - 24X + 360 = 3X² - 24X + 360 = 3[X² - 8x + 12]0 = 3[(X - 6)(X - 2)]X = 6 or X = 2




    Question 24.
    a + b

    -a + 3b

    ¾(a+b)

    Point S is on both lines and is the point at which the lines intersect.

    I disagree, they're way too low. The exam was pretty easy.

    You didn't simplify it full though and according to the teacher mark scheme you didn't need to simplify fully anyway so you might get full marks for it and 42 would be a C
    Nah you'll lose a mark because 100-25pi isn't equivalent to 25 - 5pi. You took the correct answer and turned it into an incorrect one D:
