1. I retook the paper, and honestly it was the easiest maths test from edexcel, on par with November 2013

Reps are not necessary but would be appreciated

It would be really useful if you could remember the question numbers
1. Order numbers correctly and include a key
b) 9/20=
0.45
2a. 5a*2b*3c =
30abc
b. Factorise fully 3y +6 =
3(y+2)
c. Expand x(x-3)=
x^2-3x
3.
x=9.25
4. Smallest packet was best value for money because it was cheapest per bag of crisps
5. 4 times as many red than green: There were 0.4 blue and 0.15 yellow.
0.4+0.15+4x+x=1
0.55+5x=1
5x=0.45
x=0.09
4x=0.36
Green- 0.09 Red- 0.36
6a. 20.3
b. 68.04kg
c. 2.61m
7. 3.8
8a. 4:3
b. 480 pixels
9.x= 124 degrees
10. 7.92
11.£42.29
12. x=144 degrees
13.
-2 -1 0 1 2
-1 3 1 -1 3
Draw curve
14. 3 Bars
15. No, because 7766.22 was greater than 7500 pounds
16. 128g
b.11g
17. 30.1
18. 10a^5b^4
b. y= 5p^2-x
19.11 males
20. x= 0.29 or x= -2.29
21. 29.25
22. F.d- 1.6, 3.2, 2.4, 1.8, 0.3
23.28.9
24a. -1/3x+4
b. 2x/(x+1)(x-1)
25. 80.4

what was the 128g one again?
3. For the last question I have noticed that many people, including me, obtained an answer of 40.0 degrees. This is wrong. The answer of 40.0 degrees will only get you 2 marks. We worked out the wrong angle because most people eg me thought that they wanted us to work out the included angle between the two measurements. The angle that we had to work out was one of the top angles. Moral of the lesson - read the question properly. Overall very easy maths papers.

4. So what will be the grade boundaries overall?
I got 52-55 on Paper 1 and around 58-65 on Paper 2

This is for the other angle. You then had to do cosine rule and then sine rule.
Yes, I misread the question, and I ****ing hate myself for it.

Apart from dropping 4 marks on that question I only dropped 1 other mark, will still probably get 90/100 worst case scenario. Taking into account my non calc I should still probably get an A*
6. can you please get the paper like you got for the non calculator because i can't remember how many marks some of the questions were. thanks alot

what was question 16 i can't remembeR?
8. (Original post by dh12345)
what was the 128g one again?
using the graph to find a median
https://youtu.be/ahe6jmuT2DM?t=1m2s
9. Erm what question was the perimeter of them sector?
10. the non calc and calc were fairly easy compared to previous maths edexel examS so the grade boundaries will be v high ,roughly:
A*-170/200
A-150-169
B-115-149
C-95-114
Stratified sample was 11?
Angle rules was 126
Density one was 70 something kg
Trying to remember the rest
Do you know what the question said for the angle rules one?
12. (Original post by Arsal2016)

I got 52-55 on Paper 1 and around 58-65 on Paper 2

predictedd boundaries
A* : 165 - 168
A : 135 - 142
B : 95 - 105
C : 60 - 65
13. Controversial answers in this exam
80.4/80.1 for the last question (i got 80.4)
3.7/3.8 for the trial and improvement (i got 3.7)

As they all do, it said find x.
But I can tell you the rules if that's what you mean

16. i thought 23 was 28.1
17. (Original post by AnonymousGeek)
Hey guys! I've finally got hold of a PDF copy of the Edexcel Maths 2016 calculator paper with solutions!

That is a predicted paper
18. I wrote that half of £15000 was £7000. Don't know why I thought that I'm not stupid was just a silly mistake, will probably get marked down for that
19. (Original post by alibabzo)
The answer is correct, but this is a thoroughly inefficient method.
TO be honest I don't really care about the fact is was inefficient, I got the right answer which is more than a lot of people got and I had the time so I couldn't really care less.

No way they will be that high that's ridiculous they go up 3 or 4 not 15 marks...
