    im pretty sure q8 was 106.1 (since angle = 106.06...)
    I knew something seemed wrong about that question. I got 106.1 too, glad I'm not the only one.

    What do you think the grade boundaries will be then roughly? Because those papers both felt much harder than past papers... 137 for the A^?
    I think it will be around 137-141. Most of the time with the past papers, I knew what to do immediately. In today's paper though, I really had to think about what to do, especially for the last question and the trig one where you had to find k. I thought Thursday's paper was alright though. I guess that was AQA's way of tricking people into thinking today's paper was going to be good.

    I wrote all the answers on the back of my hand, and it's reasonable to assume I cannot read my back-of-hand-handrwriting and mistook a 1 for a 7. Since both of you agreed on that, I'll change it

    For q14 you out 10 but that isn't a square number
    Sorry, I have forgotten most of the questions. Could you describe q.14 please

    i got around 150, maybe plus minus 5 marks. do you guys think thats an A^ cos most people thought the 2016 maths gcse edexcel paper was hard but in the end the grade boundaries were so high!

    1a. 30 (and -30 is probably allowed) Marks=3?
    b. -1.5 Marks=?

    2a. \begin{pmatrix} -13 & 2 \\ 6 & 1 \end{pmatrix} Marks=?
    b.  \frac{11}{8} Marks=?
    c. Because the number of columns of B does not equal the number of rows of A Marks=1

    3a. Since 1365 = 3*5*7*13 , choose any two factors, multiply those together, and write the other two factors: e.g 3, 5, 91 Marks=?
    b. Factorised, ab-11b = b(a-11) so b is an arbitrary square e.g 4, and a=36 Marks=?

    4.  2744 Marks=?

    5. \frac{4}{5} Marks=?

    6. 12.31 Marks=?

    7. 16 Marks=?

    8. 106.1 Marks=?

    9. x=-2 Marks=?

    10. 15.2 Marks=?

    11a. Draw the thing. Marks=?
    11b.  -5 <= f(x) <= 7 Marks=?

    12a. 3(5-x)(5+x) Marks=?
    b. 12n Marks=?

    13. \frac{50a^2}{3} Marks=5?

    14. a=4, b=10 Marks=?

    15. y=\frac{8x}{w+1} Marks=3?

    16a. 3^{-2b} Marks=1
    b. 5^{x+2} Marks=1
    c. 2^{3m} Marks=1

    17a. (4, -25) Marks=?
    c. The roots are x=5.79 and x=1.21 Marks=?
    18. \frac{32y^2}{5} Marks=?

    19a. k. Marks=1 Think of 19a. and 19b. as transformations: https://www.desmos.com/calculator/4kphkki8vl
    b. -k Marks=1
    c.  \sqrt(1-k^2). This is rearranging of  \sin^2 x + \cos^2 x = 1 with  \sin^2 x = k^2 Marks=2

    20a. Angle at circumference is half angle at centre Marks=1
    b. e.g Angle in triangle 90-x
    Angle on straight line 90+x
    Opposite angle in cyclic quadrilateral 90-x
    Other base angle 90-x
    Other angle in triangle 180-2(90-x) = 2x, QED Marks=5?
    There are obviously many other ways to do this. I think we all know if we got or did not get marks on this question

    21a. (0, 8) Marks=?
    b. -2x+2 Marks=?
    c. Normal equation y= \frac{-1}{2}x + 8
    So intersects x-axis at (16, 0)
    The rest is easy (show one length is twice the other) Marks=?

    22.  (-6/5, -7/5) and (2, 5) were the pairs of solutions Marks=?

    23. -1 is the constant, because

     \frac{1}{\tan^2 x} - \frac{1}{\sin^2 x}

     = \frac{1}{(\frac{\sin x}{\cos x})^2} - \frac{1}{\sin^2 x}

     = \frac{1}{\frac{\sin^2 x}{\cos^2 x}} - \frac{1}{\sin^2 x}

     = \frac{\cos^2 x}{\sin^2 x} - \frac{1}{\sin^2 x}

     = \frac{\cos^2 x - 1}{\sin^2 x}

     = \frac{- (-\cos^2 x + 1)}{\sin^2 x}

     = \frac{- \sin^2 x}{\sin^2 x}

     = -1 Marks=4?

    24. 3(2x-5)^2 - 70 Marks=4?
    dude, i swear 18 is 16y^2/5, because the area x*2x/2, and x=4y/sqrt5, so x*2x/2 = (4y/sqrt5)^2

    Isn't the area of the rectangle x*2x=2x^2? Why divide by two?

    I've just realised for the area of the rectangle question I found the area of the triangle I read the question wrong.
    I found x in terms of y though. Will I get any method marks for this?
