    ****ed it. Went to blow my nose for 2 minutes cuz of hayfever but ended up running out of time for the latter half of q8 - which means 10 marks down the drain. Also didn't finish the trig question so 1 mark lost. Overall looking at 64-65/75.

    My offer requires an A* in Maths but with only 63-64/65 in C4 and 65-66/75 in C3 doesn't look likely.

    I did the answer to the rates question to the nearest minute but i did hours and minutes...10 hours and 33 minutes, would i lose a mark? technically its to the nearest minute
    I'm pretty sure thats allowed because it didn't say give the answer in minutes.
    It only said to the nearest minute.

    I thought the paper was ok overall. There was some simple questions and some not so simple questions.

    One other thing, if you go wrong early in a question can you get method marks and ecf marks?
    You should do unless the question was a "show that" in which they would expect you to the the one they give.

    I was happy coming out of that exam predicting I got about 69 thinking that combined with my C3 of 66 is an A*. Then I've come on here and seen all you *******s found it easy! Whats the likely hood of 66 and 69 being an A*?

    For the volume I got volume=554pi -1204pi/5 = 1696pi/5 ??

    Thats what I got - hopefully it's right

    for the implicit differentiation question i read the question wrong and instead of 2x^2y i wrote 2x^2. the whole question was worth 9 marks with the first part being 5 and the second 4 but they followed on from each other and im pretty sure i did everything else in the question right, how many marks do you think i lost? im pretty sure i got 74/73 in c3 so im hoping that itll all average out to above 90. If anyone could answer please do this is stressing me out

    1) (1/8)-(15x/16)+(75x^2/16)-(625x^3/32)

    2) 0.6595 for missing value
    1.083 for estimate
    (8/3)ln2 -(7/9)

    3) dy/dx= (-4xy-2)/(2x^2+4+piSinpiY)
    X value was (3pi +62)/(pi+22)

    4) X= 60e^-2.5t
    633 mins nearest minute

    5) (-5root3)/16
    Q: (4,5root3)

    6) not sure about A- partial fractions integration. 3ln(3y+2) -2lnY + c
    Show substitution
    (4pi/3) -root3

    7) k was 8.5, volume was 1696pi /5

    8) a was 3,5,0
    K equals 2 (AP was 2root2)
    Cos= 4/5
    E was same as what others have said

    We left the EU, that's my reason for not completing the paper to a good standard
    Yeah I was also so outraged that I failed in protest

    Wtf, it was a timing issue not a knowledge one. Get outta here with that pompous attitude
    Ignore the d***head. Clearly insecure about something

    Would be very surprised if you lost a mark.

    no because this would result in an obtuse angle

    i couldn't do question 5, the one where you had to prove it = k (integral) sin2^x??? How did you do it? + for the followup how many marks would i get if I just used k =1/8 but got the integration right?

    Please can someone tell me how many marks I'll lose for this?
    On the question where you had to prove an inegral was the integral of sin^2theta by making a substitution for x I got k outside the integral as 1/8 (the answer was 8 but i just made a silly mistake taking the number out of the integral.)

    I think that would lose me 1 mark but i think the next part was solving this integral, and therefore my result would've been muliplied by 1/8 instead of 8. How many marks would i lose overall between both parts for this one error? Thanks

    My full solutions:
    4) x=e^(ln(60)-2.5t)), 633 mins
    For question four, I did
    First I found out with the x and t values given that the constant C = ln|60|
    Then I did,
    ln|x| = -2.5t +ln|60|
    ln|x/60| = -2.5t
    x/60 = e^(-2.5t)
    x = 60e^(-2.5t)

    EDIT- Just realised they are the same thing.
    My answer for the hours passed for the mass to decay to 20 was the same as you I think.

    im the same boat that question ****ed me over, but that part was only 4 marks so youve lost 4 marks maximum and maybe got 1
    Yeah apparently it was like a 5 marker so we would have got twoish for the integration alone. So surely we should lose only like 2?
