    June 2014 had slightly low boundaries. Papers have been fairly consistent otherwise. Maybe look at recent IAL papers.
    I did that paper in my mocks i think, i had two mocks June 14 R and June 14 UK last year november..

    Tbh, grade boundaries who the rest are fairly straight forward. I would just do some Gold papers if I were you.

    For this question, do you have to revert to dy/dx , cant we just keep it dx/dy and then sub y into the dx/dy to find the gradient?
    No, dy/dx gives the gradient, not dx/dy

    why not just plot the graph and find the smallest/maximum value of y?
    I've just done that and I think I get it now, thank you!

    Doesnt dx/dy not give the gradient even if you have the y value at that point?

    Simultaneous equations using the two points on f(X). remember a cannot equal 0 though...

    I just wrote it a few hours ago
    Yeah but was this a question from the C3 past paper? I want to know what question so I can have a go.

    dx/dy never gives the gradient

    Yh, I got full marks in both mocks with no papers so C3 isnt a peoblem tbh. Yh im gna do the golds, forgot about them things. Cheers

    g(x)=ln2(x)
    g(x)+g(x^2)+g(x^3)=6
    when x=x ---> g(x)=ln2(x) ---> expand the brackets ---> ln2x
    when x=x^2 ---> g(x^2)=ln2(x^2) ---> expand the brackets ---> ln2x^2
    when x=x^3 ---> g(x^3)=ln2(x^3) ---> expand the brackets ---> ln2x^3

    ln2x + ln2x^2 + ln2x^3 = 6
    ln((2x) x (2x^2) x (2x^3)) = 6
    ln(8x^6) = 6
    8x^6 = e^6
    x^6 = (e^6)/8
    x= the sixth root of e^6/8

    made it as clear as i can, hope this helps
    Thank you!!!! :-)

    I have noticed this year, M3 similar style to IAL, FP2 similar style to IAL not difficulty, physics today was also similar style to IAL.

    Basically the way I do these is by subbing in x=3, which gives (3+1)/(3-2) = 4/1 = 4, and then I sub in a really big number for example 500, which gives (500+1)/(500-2) = 1.006... From this you can see that as x tends towards infinity, f(x) tends towards 1. So the range is 1 < f(x) < 4

    You have to consider similar triangles...

    Thank you very much, was confused as the explanation before didnt make sense.

    Best papers to do if you've done all the Edexcel ones (R's and IAL's) and Solomon A-L?

    Looks like choice is between Elmwoods and Edexcel Bronze/Silver/Gold?

    Np, it seems the only Q that could really throw a full marks paper is a nasty trig Q which is probably a no go area after June 2013 despite the fact that the trig on the paper, imo, was not the hardest Q.

    I just wasn't going to look at them because it's one big amalgamation of c3 and c4.
