# Edexcel GCSE Mathematics A Higher Paper 2016 Unofficial Markscheme

1. Wait so..how did everyone find the paper as a whole? Lots of people were complaining about it
2. (Original post by polishboyy)
Guys i lost 12-15 marks, can i still get an A*
Probably, but it will be close. So you may get unlucky with high grade boundaries. :/
3. For the estimate one I did 900/19 and got 42 would that still be full marks?
4. does anyone have the full paper? so i can do it
5. Q25 worth 3 marks
6. What were the two questions where you had to use a compass , one with an angle and one with line

Really easy.
8. last years was
A* = 155/200
A = 125/200
B = 95/200
C = 65/200
D = 35/200
E = 20/200
If the next exam is hard:
A* - 157/200
A - 128/200
B - 94/200
C - 66/200
IF the next exam is EASY then it would be:
A* - 160/200
A - 129/200
B - 98/200
C - 69/200
9. Are these questions below foundation or higher? ?

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
10. (Original post by HateOCR)
I got 5x+20y=T
me too i think. I thought that was so generous for 3 marks
11. (Original post by Federerr)
I got pictures of the paper. I stole one from a empty desk lol.
Can you put the amounts of marks for each question up please ?!
12. (Original post by Federerr)

If this is true, post the amount of marks for each question please?
13. I got 6 and 2 for this q...? :/
14. (Original post by 34908seikj)
no, it would be 25(4-pi)
nooo arghh
15. (Original post by IDEKOKAY)
What was the method to find out the answer for the last question about the area of the shaded area????
16. (Original post by bethanyjx)
Wait so..how did everyone find the paper as a whole? Lots of people were complaining about it
I found it stupidely easy that i made so many mistakes. i shouldnt have been very confident
17. (Original post by IDEKOKAY)
What was the method to find out the answer for the last question about the area of the shaded area????
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
18. Could anyone sketch the circle theorems question with a solution? Cheers
19. I got 39/90 for the fraction one ok im so ppppppppppppppsssed
20. (Original post by keepyourapology)
the percentage question was 36%.
the number of females were 11.
the shaded area in a square was 100-25TT = 25(4-TT).
does it matter if it is a factorized answer or not????
