    I went through Q6 with my teacher today as he's got the paper now. Q6ai was find where X values crosses the X-axis. I got -1+root 20 and -1-root 20. 6aii was stretch graph. 6bi was show that question. 6bii is find values of k, which I got 4 and 20.

    i got around 63 marks, what grade do you reckon that will be ?

    and what was question 7a and 7b,

    i got 63 marks (without considering ECF)

    Anyone think what grade 63/75 is ?

    Thanks !!
    Given that last year AQA offered an A grade to people who achieve 64 or more marks, i would say you are in with a good chance of getting an A. I mean, w/ ecf and the fact that 2016 paper seemed a little harder than 2015, i would say things swing in your favour, but good luck w/ core 2 and hopefully you get the grade you want

    70 UMS may be around 53
    Really? I thought it would be way higher than that

    yeah I think especially cus last year was probably the highest marks needed for an A in a core 1 paper I think they will lower it

    I'm basing this off of the percentage calculations (75*0.7) of which states that the A grade could even be 60 . I'm just hoping it's lower rather than higher

    Unoffical Mark scheme for C1 AQA 2016

    It would help if you could link answers to questions as i cant remember them

    Questions:

    1) a)Asked to work out gradient of a tangent, m= - 5/3 [2]
    b)Asked to find co-ordinates of B B( - 3,4) [3]
    c)Asked to find K K= - 30 [2]

    2) a) simplify (3√5)^2 = 45 [1]
    b) i cant remember the question but the answer was75 - 32√5 [4]

    3) a) y=(x-7/2)^2 - 41/4
    b) min value = -41/4 [1]
    c) Translation of (1/2 , 41/4)

    4) a) show that (x+3) was a factor of x^3 - 5x^2 -8x + 48, p(-3) = 0, (x+3) is a factor of p(x).
    b) three linear factors of p(x) = (x+3)(x-4)(x-4)
    c) find remainder when p(x) was divided by (x+2) R=20
    d) Factorise p(x) using (x+2) R = (x-2)(x^2-3x-14) + 20 [3]

    5) a) asked to find equation of circle (x-5)^2+(y+3)^2=65 (note 65 = r^2) [3]
    b) asked to find co-ordinates of B (AB is diameter) B ( 12, -7) [2]
    c) asked to find equation of tangent at A 7x-4y+18=0 [5]
    d) asked to find length of CT = 9 [2]

    6) a) y=-32x-40
    b)Q(-5/4) [1]
    c) upside down positive graph passing through y axis at 8 [2]
    d) x = -1±√5

    7) a)
    b)
    c) definite integral = = 81 /4 [5]
    d) area of shaded region = = 45/4 [3]


    8) a) d^2y/dx^2= - 2x - 9x^2 [2]
    b) verify that P was a minimum point sub x co-ordinate of P into dy/dx (given in the question) to prove it was a stationary point, then sub in x-coord of p into d^2y/dx^2 to get +45, d^2y/dx^2>0 therefore minimum point [4]
    c)show that y is decreasing, so make your dy/dx<0 and rearrange to get into the form they wanted (note when you multiply by -1 the inequality sign flips)
    d) cant remember anything except the answers were k>6 and k<-3/2

    Answers that need a question to be assigned to
    - k=4 and k=20
    I dont know if anyone is interested but I made a more updated mark scheme that includes all of the actual questions, the step-by-step answers and where marks are allocated as well as a grade boundary guide. Let me know what people think

    I genuinely forgot to put brackets around my coordinates for the first Q would i lose a mark?

    Oh right lol if you didnt put brackets but put both the x and y value this should be FINE and get you 3 marks. However if they are feeling super mean this year you'll still get 2/3 marks but its very unlikely-you should be fine. Good luck!

    I think has in the past in core 2 so its somewhat likely something similar will appear. What is it you dont understand about it? Anything i can help w/?
