    the fact that I have every answer identical makes me feel a bit happier considering I feel like I dropped way more marks than I should have on M2 today

    It was (x-1) (x+1) (x+6)

    Got everything right but the inequality. I think I wrote 10x = -12 and then misread it as -2 so ended up with x < -1/5. That is painful - how many marks was it? Goodbye 100UMs

    For section b when we had to factorise fully. i wrote: (x+1)(x+1)(x-6) stupidly. would i still get that mark? i also wrote: x=6, x= -1. :/ i cant afford to lose at least one mark anymore...

    If you put the binomial expansion the other way around i.e. starting with 16 and ending with 81x^4, is it still correct?
    Also for the question where it said to show that the curve is above the x axis, I used b^2 -4ac < 0, I am not sure if thts the correct way to do it.
    Just making sure.
    no you had to use the lowest point from completing the square which was -2,1 if I'm correct

    I think i may have dropped around 12 or 13 marks due to some silly mistakes and 12 part i, do you think there's a chance I might still get an A?

    You 100% will don't worry im thinking around 58 for an A as student room is going to have people that want to do really well you can't judge it by this community getting 65+

    However you need to obviously do the same with c2 and s1!

    Yeah, it's fine

    The discriminant being negative shows that their are no intersections with the x-axis, and if it's a positive quadratic that does imply the whole thing is positive, but I think you'd have to justify this carefully

    For the question where you had to prove curve was always above x axis I wrote the x value for minimum point wrong but wrote y as 1 would I still get the marks?

    Ok, first of all - 'retarded'? Really?

    Second of all, when I'm doing exams i don't count the marks as i go along -_-
    But if you dont make a mental note as to where the 'End of Questions' phrase is, or check that there are no questions on the back page, that is, well, retarded. Why risk it for a chocolate biscuit?

    Thanks for the reassurance. I'm hoping S1 and C2 go better so I can get an A overall.

    q1) a=(pie)r^2(x+y) when r>0 find r
    the binomial: (3x-2)^4


    q12: y=2x+k, 3x^2+12x+13
    ii) complete the square and explain why the curve doesn't go below the x axis
    iii) What is k when the line touches the minimum point of the curve.
    9b) x^2 is an integer - x is an integer
    3(b) (25/9)^-1/2
    3(a) 10^0 or something

    11i: 2 marks
    11ii)
    11iii) 6 marker
    12i) 5 marks
    12ii) 5 marks
    12iii) 2 marks.
    binomial - 4 marks.
    9a - 2 mark
    9b- 2 mark
    3(a) - 1 mark
