    The grade boundaries will be pretty high, it was quite an easy exam imo
    Agree. Reckon the grade boundaries will be 99 for an A*, 98 for an A, 97 for a B, 96 for a C ahaha

    Hey, if anybody is willing to contribute the answers, and preferably the questions, then I shall set up a mark scheme for you all. Thanks in advance!

    Can people please attach question numbers to their answers? Method would be appreciated.

    Question 1. What is the volume of the prism?
    Area of face = 30cm² Length of prism = 25cm.

    30cm² x 25cm = 750cm³

    Question 6(?). 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 (?). X² = 4(X-3)²

    X² = 4[(X - 3)(X - 3)]
    X² = 4[X² - 3X - 3X+ 9]
    X² = 4[X² - 6X + 9]
    X² = 4X² - 24X + 36

    0 = 4X² - X² - 24X + 36
    0 = 3X² - 24X + 36

    0 = 3[X² - 8x + 12]
    0 = 3[(X - 6)(X - 2)]

    X = 6 or X = 2
    Q?? - Estimate 892/18.9 (or something idk) (2 marks - maybe)
    Round to 1sf
    900/20 = 45

    Q?? - Angle = 69 (4 marks [I think])

    180-48-48 = 84 (angles in a triangle sum to 180 & base angles in an isosceles are equal)
    84/2 = 42 (angle at the centre is twice the angle at the circumference)
    (180-42)/2 = 69 (angles in a triangle sum to 180 & base angles in an isosceles are equal)
    Therefore angle = 69 (alternate segment theorem)

    Q?? - Angie does not have enough varnish (5 marks)

    Total area = (4x10) + (2x2.5x2) = 50 metres squared
    Litres required = 50/5 = 10 litres
    Angie has = 3 x 2.5 = 7.5 litres
    10 litres > 7.5 litres

    Q?? - find shaded area of triangles in square= 25(4 - π) (5 marks)

    Square = 10x10 = 100 cm squared
    Circle = π x 5 squared = 25π
    Shaded = 100 - 25π = 25 (4 - π)

    Q25 - find the shaded area = 3 - root6/12 (3 marks)

    (root2/2 x root2/2)x 1/2 = 1/2 x 1/2 = 1/4 cm squared
    (root3/3 x root2/2) x 1/2/ = root6/6 x 1/2 = root6/12 cm squared
    1/4 - root6/12 = 3/12 - root6/12 = 3 - root6/12

    That's all I can remember for now

    1/4 - root6/12 = 3/12 - root6/12 = 3 - root6/12

    That's all I can remember for now
    Yeah I got all the same answers. Does anyone remember what they got for using the graph to estimate the x^2+4x-2=0 etc.

    Sh¡t I got 7 zeros at the end of my answer not 8
    (3.5x10^6)/(5x10^-3)
    3.5 / 5 = 0.7
    indices rule 6--3 =9
    0.7x10^9
    put in standard form
    7x10^8
