# Edexcel GCSE Mathematics A Higher Paper 2016 Unofficial Markscheme

1. What was the probability question at the end? Not the answer but the sums and numbers involved.

I completely screwed the test up - in my last mock exams I've got 95-98 every time, this time i cant even see myself getting an A*. Went horribly wrong
2. Last answer was 3 root 6 over 12
3. (Original post by louisemayorx)
have i lost hopes of an A* if I've lost about 11-13 marks?
You can make up the difference easily on the calc, 9th of June, you can do a lot of revision in that time

It depends how many marks are on the question, you got the x10^8 correct so you might be able to pick up at least one mark.
It was out of two so probably got one. For the second part of the probability question with tree diagrams, do I get one out of the two marks if i selected the correct numbers to multiply?
5. What did people get for the standard form question?
And what was the method for the last question?
And the one before the last one with the like 1/X2 and the fish symbol?
6. What was the first question again?

If it was out of 2 marks then you wouldn't get any, I don't think. 1 mark for method, 1 make for correct answer. You didn't do either in that case.

and probably, yes.

Standard form = 7x10^8
Last question:

The large triangle was 1/2*√2/2*√2/2 = 2/8 = 1/4

The small triangle was 1/2*√3/3*√2/2= √6/12

Large triangle - Small triangle = gray area

1/4 - √6/12 is equivalent to (3 - √6)/12

the second to last question was inverse proportion, where K=100

If anyone is struggling with a question, tell me the details of the question and I'll provide an answer for you to stop ye debating (hopefully)

If i factorised the envelope question, so I wrote 5(x+4y) would i get a mark or two ?

Its not even like i assumed i made mistakes, this is the first paper I've ever come out of and can say before its been marked I've lost a minimum of 12 marks, and I've learned of like 8 more I've lost. Im praying the calculator paper is my thing. To be honest, I've been getting A stars in all my mocks, but my GCSEs have all been really poor showings by me - i haven't truly finished one exam when before in my mocks id finish everything. I do not have a clue what has become of me
12. On a circle theorem question could you get some marks for just correct reasons but not method?
13. Guys what did you get for the Vector questions? xd

Last question, for 12 B on bisecting questions, was it a triangle? or what did yours look like?

It depends on what you did, you might.

i guess u get both since technically when u open it out u get the same answer. i did the same thing u did on the vector questions (both of them)

Thanks for the help, people were saying no but i was thinking that it is the exact same thing
19. LOL i got 91
20. for the last question, I somehow simplified (3-√6)/12 into -√6/4

Is that wrong and if so, how many marks will I lose ( I followed all the right workings)
