    Thought it was a good paper.
    Couldn't do the ranges question and the why wasn't it inverse (many to one apparently).
    Question 7 was a ***** but I think I powered through.
    ...Marrrrkkkkscccchhhhheeeemmmmm e.
    Please :puppyeyes:
    EDIT: YAY! :woo:
    I hated the range Q as well but in Q7 can u loose marks for not converting it into appropriate hours ???

    looking at that mark scheme the amount of stupid stupid mistakes i did was unreal.
    im so so annoyed at myself, because it was a relatively nice paper(so i reckon they'll raise grade bounderies), i just was an idiot!
    really needed to ace this so c4 wouldnt be as tough :'(

    Guys for 6C the answer is (x-3)^2 - 4 but I put it in wrong form and said it was f(x-3) -4, would that give a mark 'cause I did realise the transformation of it but just didn't read it properly to put it in x^2 form?

    So I differentiated correctly, separated the e term and removed it from the equation and got the correct x values for 5d but forgot to put those x values back in the formula to get the y values.

    How many marks will I get for that bit d'you reckon?

    I think I got 68/69. 5 marks thrown away due to stupid mistakes like making tan theta = 1 instead of 1/2. Will this be enough for 90 UMS?, as i need an A*. I'm so worried about C4 now.

    That part of the question carries only 3 marks, I too made the same mistake,we might get some marks since we had misread the question and that too many of us.

    yes, unless the A boundary is above 67 which is incredibly unlikely
    Hope the grade boundries will be low I need a high mark in C3.:eek:

    I believe it was a ridiculously easy paper.
    There were some tricks,however.
    Question 1 the "2".
    Question 7,where students should include all decimal places in their calculations and convert it to hours and minutes.
    Let's hope there wont be a downgrade.I dont think there will be one,though,since most people messed up.
