# Edexcel GCSE Mathematics A Higher Paper 2016 Unofficial Markscheme

1. (Original post by Azzam240)
I did 0.8 x 0.95 and got 75% as my answer. Was that right???
0.76

8 x 90 + 8 x 5 then divide by 1000

as you're doing 8/10 * 95/100 = 760/1000

That was a tricky one, everyone at school seems to have different answers:
Mine being (2 - root 6)/12.
I'm 95% sure the answer to the last one was 3-6^1/2 all over 12

I got 72 for circle there on I think

Same Somewhat reassuring, but loads of people at my school seemed to get 69

For the question with the answer 10-5m, is it wrong to put 5(2-m)?
Yes as -5m+10 is already simplified, no need to factor it.
5. What do you guys think are gonna be the grade boundaries? I think I didn't do all that well, I looked over the paper, I got around 70-80

Yeah I got that )
Same

I managed to wipe out all of my surds because of using Pythagoras multiple times… slightly concerned but it was only 3 marks I guess ¯\_(ツ)_/¯
I ended up using pythagoras as well, tying to work out the length CD or something!! No clue why though when it asked for area haha oh well

yep guys it was 69. Lots of steps about theorems but the answer is 69
9. How many marks was the last question??
The one that was 3-(root6)/12

an abundance of people people got 72

The question said "what is the probability it does NOT rain, AND it gets cancelled" though? So it was 0.8*0.05=0.04
Yeah the question was definitely that, I got 0.04 too! yay
12. It's not 18 because you have 3x you have to divide by three so you get x=6 which was the right answer, along with 2.

The one that was 3-(root6)/12
it was 3
14. Question 4)a) I think was g^6 / g^4 = g^2

People have been putting the answer but not the question so I'm pretty sure that's what it was
15. Any unofficial mark schemes ?
16. How many marks was the question that was x^2= 4(x-3)^2
That the answer was x=2. X=6????

The question on Circle Theorem's was 69 degrees.

Does anyone remember questions. I'd be happy to confirm the answers. Question numbers will help, but mainly the content of the questions.
18. No it doesn't mean it's wrong

For the last question, I had an answer of 1/3cm^2.... thinking that if you're doing 1/2(base x height), the 1/2 would become the power of 2. It wasn't until after the exam that I realised that 1/2 and ^2 aren't inverse functions...
I don't know what was going through my head.
The last question didn't have a 1/3rd in, I don't think, the area of the big triangle however was 1/4

Yeah I ended up trying to use Pythagoras too xD
