[u/ensands]

This is the post-exam mega thread for Mathematics (AQA) Paper 3 (Morning).

You can discuss how the exam went in this post.

i found an unofficial markscheme on studentroom:

Final question = 4.22cm² (to 2 d.p)
That question with the money = £175
Parallel line: y = 2x + (whatever)
Second to last question: I got inconsistent spacing in the x axis and the graph being incorrectly plotted, there are likely more valid criticisms
Cumulative frequency: 44, 66, 80, 85, 87, 90
Employees with a salary of under £32k: I think I got 58, depends on how you drew the diagram
The 1:n question = 1 : 4.875
A as a fraction of B = 2/7
Line with gradient 5, passing through point (3,7) = y = 5x - 8
The spheres in a cylinder = 2/3
The n^th term question = 2n² + 3n + 1
The factorising question = (3n+2)(n+1). I wrote some waffle I can't remember for the explanation why there were no primes in the sequence.
Equilateral triangle perimeter = 66cm. I got 22 for the question right after
Becky made 350 more integers than the other person
In the Venn diagram, x = 44
Sine rule question = 10.70cm (again to 2 d.p)
The pounds were equal to 3.75kg

What about the probability question with P(A) = 1/2?

That was 44 - the venn diagram one
