    Thank you so much!
    If you had a negative x coefficient, would you have to change all the negative signs to positive signs? I'd work it would with a pen and paper, but I don't have any on me at the moment.
    You complete the square normally and you'll see there will be a negative sign in front of the brackets. You have the make the whole equation be as high as possible (that's why it's called max turning point) You still do the same thing though (make whats inside the brackets 0).

    I've never heard of mathswatch before. I'll go check it out now! My old maths teacher (who was great; I was able to move up a set at the end of last year) said Corbett Maths was really good. I got some practise papers and the like from there, and loads of other people in my class said it was great.
    How did your maths test go?
    Corbett Maths? I'll check it out, thanks for the advice.

    My maths test was pretty terrible. It was nothing like the past papers! Or even specimen papers! Nothing could have prepared me for that. I doubt I even got 50% correct and we have our third paper on Wednesday.

    How about you? Any maths tests?

    Maths tests always go terribly. The thing you've got to remember is that it went terribly for everyone else as well!
    No maths tests yet, but I've had one in chemistry, one in physics. I have a biology one on Tuesday and a Spanish one next Wednesday. My French teacher has warned us that's we'll be getting a controlled assessment task within the next week or so. We're finishing our geography course work, so we have a high-control assessment coming up soon.
    Such fun.

    Surely that would mean x would have to be infinite, then? Can you get x as being infinite?

     y = -x^2 + 4x + 1 ,
     y = - (x - 2)^2 + 5 ,
    because there's a minus in front of the  (x-2)^2 , making x infinity will make y be negative infinity. You want the bit inside the brackets to be as close to 0 as possible, since you're going to end up squaring it, but then also making it negative.

    So x would be +2?

    I lovvee gaming!! I like to play Cod and Transformice ( which is gonna have to stop during this year ) I guess I'm kinda ready, my dad is already getting me a maths tutor so I can boost my predicted C into at least a B

    My subjects are:
    Maths *Edexcel*
    English Lit *AQA*
    English Lang *AQA*
    Religious Studies *Edexcel*
    Food Technology *AQA*

    I have 3 sets of mocks, which I believe is really good (in October, January and Easter). My mocks start tomorrow with paper 1 English language which I should now be able to smash. Aiming for at least 60-70. Then I have got English language paper 2 on Thursday. All the science's next week along with PE and English literature paper 2.
    Good luck with your mocks!

    Does anyone know approximate grade boundaries for AQA English Language papers. What raw mark should you be aiming for, for say a 8/9. English usually has relatively low percentage grade boundaries? Does this seem about right: 7- 56/80, 8- 62/80, 9- 68/80. I know it's hard to predict grade boundaries especially with a new spec, but does that seem right?
