Re: AQA Maths GCSE Unit 2 - 11th June - Unofficial Mark SchemeI had about 25 minutes left but I did find a bad mistake and corrected it(Original post by zayba)
i dont even remember that 1
didnt c itwas that the foundation paper or higher??? I did the higher but ran out of time!

Re: AQA Maths GCSE Unit 2 - 11th June - Unofficial Mark SchemeI've heard that its 77% but I'm not too sure(Original post by Student16S)
Roughly how many marks would it be for an a* ? -
Re: AQA Maths GCSE Unit 2 - 11th June - Unofficial Mark Scheme46 an a* in the past papers has been≥45≤48-I think.(Original post by Student16S)

Re: AQA Maths GCSE Unit 2 - 11th June - Unofficial Mark SchemeI estimate A*-46 A-36 B-27 C-19 D-12.You are also allowed to scrape an E.(Original post by ShannonS)
What are the grade boundaries for all the grades? -

How did you work out the 4/5 thing? -
Re: AQA Maths GCSE Unit 2 - 11th June - Unofficial Mark Scheme
question 17 or "the grid question" can be worked out by finding out what the different co-ordinates are:
The first thing i did was re-arrange the equation and draw a table with A-D and the co-ordinates.
the equation was y=-2x+6
using that i knew that B was (0,6)
And because A's y value was 0, i could use the mx part of the equation to find the x value, which is 3. (this is how far you go back from B to get Cs x value)
with that information i plotted where C was in terms of B , which was 3 to the left and 6 up, making C : (-3, +12)
Now i knew what C: (-3,+12) and D: (-7, 0) were, i could find the gradient and intercept by finding where C was in terms of D.
To get from D to C on the x axis you go across 4
To get from D to C on the y axis you go up 12.
The gradient is therefore 12/4 or 3.
You can use the 3 in an equation for one of the C or D x values, so if x=-3 for c then 3x would equal -9, and to get to 12 you add 21. the same with x=7.
the final equation answer should of been y=3x+21
(I think factorising the equation to make y/3=x +7 is right but i don't think the examier would accept it since equations are in the form y=mx+c) -
Re: AQA Maths GCSE Unit 2 - 11th June - Unofficial Mark SchemeNope I found it hard too hopefully the grade boundary will be lowered!!!!(Original post by ShannonS)
I seem to be the only one who found this paper hard! I didn't understand the last few questions and my mind went blank on easy ones! What is the lowest you can actually get on this test? -
Re: AQA Maths GCSE Unit 2 - 11th June - Unofficial Mark Scheme
I found it really hard.
How many marks do you think i would get for the graph question as i put y= 4x + 28 and put the number -3 somewhere. Sorry for little detail but this question is stressing me out as everyone else in my class got it right ( y= 3x + 21), how many marks was the graph question btw?
On the last question i put 4 and -16, how many marks do yoy think i would get for that?
Also for the 3 to the power of 2012 question i put 9 but that was a quess and i didnt really put any logical working down so how many marks do you think i would get for that?
Thanks and good luck!Last edited by wombie97; 13-06-2012 at 18:00. -
Re: AQA Maths GCSE Unit 2 - 11th June - Unofficial Mark Schemei hope so!! I dont get to find out my mark until the end of summer so i will definitely worry all summer! haha(Original post by candyfloss.head)

Re: AQA Maths GCSE Unit 2 - 11th June - Unofficial Mark Schemethe last question you should have got 4 marks out of th 5 because i made exactly the same mistake! and im not sure about th 3 to the power of 2012 question as many people are unsure about what the mark scheme will be like for this.(Original post by wombie97)
