# Edexcel GCSE Mathematics A Higher Paper 2016 Unofficial Markscheme

1. (Original post by dh12345)
how many marks do you think i will get for the circle theorem question for saying .... the tangent meets the cirlce at 90 degrees - that theorem and then i said it was an isoceles so the two angles are equal but then because couldn't find anymore reasons i just worked it out really quickly at the end showing all working but not giving any reasons and i put 69 degrees
you should get the full marks, but since it says all the reasons you could get 4.. not certain though :/ you won't get less than 4

well to be 100% sure you need at least 78 marks for an A, depending on grade boundaries you might need less
Okay thanks i do better in cal so hopefully i will get that
3. For the last question I figured we had to write it as a whole number so after getting to the 1/4 - √6/12, I converted them both to decimals instead and ended up with 0.206666... Will I only get two marks for not including that last step or will they see my answer as fine (assuming it was correct haha)?
4. Hi, could you do a foundation one too please? Linear
5. (Original post by LogicalFallacy)
That was correct.
SAME i got that!

Got around 92. Not bad. What does everyone think the grade boundaries will be like? It seems rather split - many people found it hard, others found it relatively easy.
Ill be honest, i hope most of the country did **** so that the grade boundaries are low, but im hoping for 150 marks for an A* and 134 for A
7. I put 0.7x10^9 instead of 7x10^8 for the standard form. But aren't both acceptable in standard form anyway...?

I have a feeling it'll be 160s for an A*, but lol I agree with you I'd prefer it if it was lower to be on the safe side haha. It has to be seriously hard for it be dropped and the test hasn't made it onto national news yet so the grade boundaries will probably be high

yes it is finee
pheww ty
12. Can someone please post the full unofficial foundation mark scheme please? ASAP
13. Can there be a mark scheme for the foundation paper please
14. what would 157/200 be?
15. The rotation was clockwise I am positive

I did that, we'll get 1 mark because standard form has to be a digit between 1 & 10

Im hoping that 64 will be an A. I think this was an easy paper so higher than last year.

you are negative the rotation was anti-clockwise by 90 degrees

You'll get 2 method marks for 1/4 - √6/12

and 1/4 - √6/12 = 0.045875854768068491816892993774 509050669504376611944155963
20. Two questions:

- In Question 12 I put as my answer 75π cm² instead of 100 cm² - 25π cm², will I get any points?

- In Question 4 C, I put (n-0)(n+7) instead of n(n-7), will I get any points?
