    Hi guys.

    Sorry no mark scheme from me tonight - I forgot to collect a paper from our exams office before I came home.

    Hopefully someone else can fill the void.

    Edit: I see Jr is in the house.

    Can you tell me how many marks I've dropped?

    7. Used sin(171) to get volume of pyramid = 9.67, because 171 was less accurate than 8.68..

    DROP 1

    8. Wrote dr/dt=-kroot(r) so wrong answer, method marks?

    DROP 5 OUT OF 7 PROBABLY

    4. Only got 2 stationary points.

    DROP 3 PROBABLY

    10. Couldn't prove (iii) but got the expansion correct.

    DROP 2 OR 3

    For the differential equation question I I put dr/dt=(square root(5))/k at the start does that means I got whole question wrong :///

    7: lose 2 probably

    4: lose 3 probably; 4 would be harsh.

    9: If you've not stated x=0 then yes, lose 1

    8: should have been r= (3/2(3.24t+1.8))^2/3. If you had this then you shouldn't lose a mark.
    For the differential equation I didn't simplify the r bit (left it as 2/3r^3/2) how many will I lose?

    How many marks lost:


    i) integrating tan2x as ln secx/2
    ii) only giving one set of coordinates for stationary points
    iii) giving the right equation of r in terms of t but not having r on its own (something like (2r^3/2)/3

    Are there any questions that people are unsure about and would like a second opinion on?
    For the balloon question I got almost there but had (2/3)root of 4...t+2...)
    Do you still think I will get most of the marks?
    Also, will I get ECF marks in part 2?

    How many marks do you reckon I would lose for reading it an directly proprtional isntead of inverself proportional? All 7 and then the 2 on the next one :/?

    can you give us an estimate at grade boundaries? How difficult the paper looks?
    thanks.

    Yes, for the differential equation, I put dr/dt = (square root of the radius)/k and got the whole thing wrong will I get any metho mark ? Thank you

    What was the correct answer to 7) iii?

    I did (AB)(AC)sin171.3 x 1/3 x 1/2 x AD. Is this the right method?

    Hi Mr M! I read it wrong for the balloon and said it was directly proportional instead of inversely proportional. How many marks do you think I would lose?

    how many marks do you think i would have lost for the rate question as i did directly proportional instead of inversely? will i still get one?
