Edexcel GCSE Mathematics A Higher Paper 2016 Unofficial Markscheme

Scroll to see replies

My predictions for grade boundaries (I've tried to look at the jumps between 2010-2015)

A*- highest the boundaries could go: 165-168/200
A*-lowest grade boundaries could go: 160-162/200

It is unlikely they will keep it around 155 like last year my personal thought because the test was doable

A-highest the boundaries could go: 133-136/200
A- lowest the boundaries could go : 128-132/200

You know question 14 - the one that was 100-25π - the question said leave your answer in its simplest form. I'm just wondering, were we supposed to put 25(4-π) ? Or is it "simpler" to put 100-25π ? :smile:


Good question. If anyone could answer this, it would be appreciated.
Yes u downs, cuz u don't add a different terms

Wasn't the probability tree 0.8 x 0.95? Some people are saying 0.8 and 0.04?


I got 0.8 X 0.95 = 0.76
Exactly, same here
are we sure that Question 22 was asking for the angle at the base of the angle?
Could you please post the foundation paper mark scheme on this thread? Thanks 😀
What was question 7 which answer was a coordinate (-3,-2) I think? Like what was the q about ????

Yeah that's what I put.


thanks for the reply.
did u guys find it hard or was it easy.. wanna predict the outcome of the grade boundaries

For the circle/shaded square area question (Answer currently on unofficial mark scheme as 100-25pi, however in I factorised it to it's simplest form as the question asked and ended up with 4-pi


i got 100-25pi then i simplified it to 5(20-4pi)

It gave you a line, with the mid point and the co ordinate A which you had to use to find B.

It was a right angled triangle with the sides attaching to the right angle both being 'square root 2' / 2. Then a shaded portion inside the right angles triangle making a thin triangle on the hypotenuse if that makes sense. The length of the side minus the base of the shaded triangle was 'square root 3' /3. Then it asked for the exact area of the shaded triangle.



You don't need there hypotenuse for that 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
If I got 40 marks on this paper would that be a c or would I maybe get a b??

It was looking for the angle near the bottom yes, touching the tangent and the right side of the triangle
what do you guys think will be marks to get an A with both papers?
what do you think it will be to get a b

Definitely a C, if you want a B aim for the high 50s in the second paper. You can do it
can someone remind me what question 6 was about?
