    Question 9 was about T Envelopes with a formula for small (x) and large (y).

    I think the answer was T = 5x + 20y however it may have needed to be in simplest form in which case it could have been T = 5(x+4y)

    If students didnt do so well on this paper, will they lower the grade boundaries slightly? I don't even think I scraped a C :'(
    im sorry to say they will probably be higher than average
    but depends on paper2

    Shucks. Many people put around 50ish apparently so there may be some leeway on that. I can only hope that there is

    No, It didn't specify it had to be in it's simplest form, however would make sense that such a simple question is worth 3 marks if you had to do that.

    For the circle and square question, I wrote

    10 X 10 = 100CM"2
    Area of circle = PIE R"2
    and then did 100/25
    How many marks do i get?

    1 I'd say since you got the square correct, but didn't get the circle correct. it wasn't 25, it was 25pi

    then 100-25pi == 4(25-pi)

    Probably just 1 for the 100cm"2

    How many marks will i have dropped for these answers;
    75TT (did have 100-25TT written down) but didnt think to leave it like that.
    0.4 for the probability one.
    Table of values- 1, 0.25, 0.4.
    Read the scalar wrong for the vector and did 1/3 (a +b).
    For the x and Y question with the quadratic. I did y= 6 +x (instead of -x) and drew a straight line and found 2 points of interception going through the curved parabola.

    1/3(3a-3b) is just a-b.
