# Edexcel GCSE Mathematics A Higher Paper 2016 Unofficial Markscheme Watch

1. The probability answer is 0.04.
2. Are the marks for each question going to be updated?
3. Fs thought it said amount if female teachers I wrote 90 teachers in total but put 54 in the answer box😂😂
4. I have a question for the foundation paper
5. For Q.9 how many marks will I lose for working out that the correct amount of female teachers but not finding the total. (I forgot).
6. (Original post by cicelym)
For one of the questions, I stupidly wrote 4.0 instead of 0.04, however I wrote 0.04 in my workings, do you thing they would still mark it correct?

I have a question for the foundation paper
This is the higher thread, probably best finding the foundation one, if there is one.

Haha same, I think we only lose 1 mark though.
9. when will the unofficial mark scheme be released for foundation tier?
10. (Original post by gcseexamz)
im sorry to say they will probably be higher than average
but depends on paper2
Well calculator paper is easier in my opinion and I always do about 10% better on that I was hoping for a B and now I'm praying for a C *cries in corner*
11. For the standard form question & Fractions what are the correct answers
12. (Original post by junayd1998)
Attachment 538865 Also this one as well did i do that correctly. hope i did.
Yesss, that's right
13. Yes, you could have also factorised it as (3x-6)(X-6) but you get the same answers
14. (Original post by LogicalFallacy)
Hey, if anybody is willing to contribute the answers, and preferably the questions, then I shall set up a mark scheme for you all. Thanks in advance!

Can people please attach question numbers to their answers? Method would be appreciated.

This will be updated as I go along.

Question 1. What is the volume of the prism? (2 marks)

Area of face = 30cm²
Length of prism = 25cm.

30cm² x 25cm = 750cm³

Question 2a. Reflect shape in line X = -1 (2 marks)

Accept correct reflection.

Question 2b. Rotate shape 90° anticlockwise. (2 marks)

Accept correct rotation.

Question 3. What is wrong with the questionnaire? Give two reasons. (2 marks)
Attachment 538813
'Too vague (i.e. not 1-2, 3-4 etc.)' and 'no time frame (i.e. not per week, per month, etc.)' are accepted.

Create a better survey for him to use. (2 marks)

Why is his maths class not a good sample? (1 mark)

'Too small' and 'may be biased' are accepted,

Question 4. Simplify. (all of question 4, 6 marks)
P2 x P5 = P7

G6 ÷ G4 = G2

(K3)2 = K6

10-5m

Factorise n2 - 7nn(n-7)

Question 5. Estimate 892 ÷ 18.9 (2 marks)
Round to 1 significant figure

900 ÷ 20 = 45

Question 6. A teacher is picked at random. 3/5 chance they are female. 36 are males. (3 marks)
How many teachers are there altogether?

2/5 of teachers are male. 36 are male.

2/5 of total = 36
2 x 18 = 36
18 x 2 = 90.

Question 7(?). Point is the midpoint. Where is the other end?

Question 10(?). Can the floor be varnished with 3 tins of 2.5 litre varnish and it is 5 m2 per litre. (5 marks)
Attachment 538829

2.5 m x 6 m = 15 m2
2.5 m x 6 m = 15cm2

10 m - (2.5 m - 2.5 m) = 5 m
6 m - 2 m = 4 m

5 m x 4 m = 20 m2

15 m2 + 15 m2 + 20 m2 = 50 m2

5 m2 per litre, 50 m2 ÷ 5 m2 = 10 litres

2.5 litres per tin, 3 tins, 3 x 2.5 = 7.5 litres.

Not enough, 7.5 litres is less than 10 litres.

Answer is 'not enough' with evidence.

Question 11(?). What percent of his total spending is his rent now?

Question 13(?). How many females visited the art gallery?
66 students went on the trip.

Males - Bowling - 4
Females - Bowling - 6
Total - Bowling - 10

Males - Art Gallery - 9
Females - Art Gallery - 11
Total - Art Gallery - 20

Males - Skating - 10
Females - Skating - 26
Total - Skating - 36

Males - Total - 23
Females - Total - 43
People - Total - 66

Question 14(?).
Attachment 538769
Area of square = 10cm x 10cm = 100 cm²
Area of circle = π5² = 25π cm²
Area of shaded = Area of square - Area of circle = 100 cm² - 25π cm² = 100 - 25π cm²

Question 15(?).

Compare median, interquartile range and range.

200 x 25% = 50
200 - 50 = 150

Question 16(?). (3.5 x 106) ÷ (5 x 10-3)

7x108

Question 17(?).

x = -0.4 or x = 4.4
x = -1.1 or x = 5.1
x = -1.7 or x = 4.7

Question 18(?).
7/5

2 4/5

4/5

Question 19(?).
x < 7

Question 20(?). Solve X² = 4(X-3)²
X² = 4[(X - 3)(X - 3)]
X² = 4[X² - 3X - 3X+ 9]
X² = 4[X² - 6X + 9]

X² = 4X² - 24X + 360 = 4X² - X² - 24X + 360 = 3X² - 24X + 360 = 3[X² - 8x + 12]0 = 3[(X - 6)(X - 2)]

X = 6 or X = +-2

Question 21(?). What is the chance of the match being cancelled when it does not rain?
Attachment 538811
0.8 x 0.05

Question 22(?). What is the angle?

Angles in a triangle add up to 180°, base angles in an isosceles are equal.
180° - 48° - 48° = 84°

Angle at centre is twice angle at circumference.
84° ÷ 2 = 42°

Angles in a triangle add up to 180°, base angles in an isosceles are equal.
(180° - 42°) ÷ 2 = 69°

Question 23(?).
a + b

-a + 3b

¾(a+b)

Point S is on both lines and is the point at which the lines intersect.

Question 24(?).
Table - 100, 25, 4

Question 25.
Attachment 538759

(3-√6) ÷ 12
Question 20 factors are (3x-6)(x-6) i don't see how its x= +-2 ?? i got 6 and +2
15. (Original post by Mahdihassan)
For the standard form question & Fractions what are the correct answers
I think the standard form one was 7x10^8 or something but I put 7x10^3 do yuo think I will get a mark for putting 7?

Well calculator paper is easier in my opinion and I always do about 10% better on that I was hoping for a B and now I'm praying for a C *cries in corner*
given how easy this paper was, I think the calc will be quite a bit harder.
17. have i lost hopes of an A* if I've lost about 11-13 marks?
18. 90 teachers?
19. (Original post by louisemayorx)
what is the absolute highest that the grade boundaries can go for an A* out of 200?
probably 188 out of 200 is max
20. This is really helpful to find what I roughly got for my GCSE maths exam.

Thank you
