UNOFFICIAL MARKSCHEME Edexcel Maths Calculator paper 09/06/2016

Why bother with a post grad? Are they even worth it? Have your say! 26-10-2016
1. I screwed up math today. I hoped for B, now I am scared I'll even get 'C'!
I've got 46 points on the first paper. How many more points do I need to have 'C' in overall pls.?
Sorry of this was asked before, I'm just gutted and can't think.

A* = Roughly 169
A = Roughly 132
B = Roughly 98
C = Roughly 77
77 for a C???? No, it'll be like 69 or 70. That's a really drastic change from last years grade boundaries????

Says 404 error??
How do we even know that this link will even work as it looks like he has been made to remove the one he did for Paper 1???

Because it is a cubic graph, the points should be connected with smooth curves, check on desmos or a graphing app

Oh nooo does that mean you get no marks for it at all?
5. can someone post the questions?
6. (Original post by claire_22)
Did anyone else get 80.1 for the last one? It's because at some point I rounded it to 2dp and then worked it out with that. I wasn't sure whether to round to 2dp or 1dp (if I rounded to one at that point sna then carried on my final answer would have been 80.4). I ended up deciding to go for the 2dp and then getting 80.1 because it was more accurate but I'm not sure cause everyone says 80.4
I also got 80.1 We'll lose an accuracy mark. Doubt we'll lose 2. So 5/6 is not too bad for a 6 marker.
7. I left it like that tol, it should be full marks.

for question 1b i left my probability as 9/20... how many marks would i have got for that?
8. I got 28.94 for the sector question? What question number was it?
And what was the question for the bounds? I want to rework it out

I actually feel really confident with this paper, there weren't really any questions that were very challenging, and hopefully I got that a* I also heard from other people that this was easier than the non-calc paper

Also, for Q24, I think you could simplify 2x/(x+1)(x-1) to just 2x/(x^2)-1, as this would technically be more simple
Actually 2x/(x+1)(x-1) is more simplified

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. 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. -1/3x+4
24. 2x/(x+1)(x-1)
25. 80.4
23. Was part a of 24.
The answer for 23 was 28.9cm
11. I got 40 on the last question, can someone tell me how to get 80.4. I used the sine rule and did 0.5x7x8xSinC=18
Then i worked that out until i had SinC=some thing and i did shift sine that number and got 40? People are telling me i had to use consine rule. And i knew my answer was wrong anyway becasue i checked it with the consine rule and i got some werid number

A* = Roughly 169
A = Roughly 132
B = Roughly 98
C = Roughly 77
169 for an A*? What makes you think that?
13. (Original post by Disfuligee)
Yes they are the same thing just multiplied by -1/-1
How many marks would this get
3-x/(2x+4)(x-3)

14. For the simplifying quadratic fraction I got -3x-4
Anyone else???

You'll get marks for plotting the points, but you can't get all the marks I'm afraid

If I have the correct numbers,This is one way of doing last Q

Area = ( absinC)/2Sin-1 C

= 18x2/(7x8)= 40.00520088 degrees (DO NOT ROUND)

a^2 = b^2 + c^2 - 2 x b x c= 27.20955764 cm (DO NOT ROUND)

Cos A^-1= (b^2 + c^2 - a^2) / 2 x b x c

= 80.37550115

= 80.4 degrees

30.1
I got 5.1 because i used triganomatree to work out the two angles together and i took away 30 to find x. But i probably got it worng because i couldnt figure out which was adjacent or opisite since the hyppotonusewas not adjacent to the angle so ur probably right lol
19. I said 9 out of 20 but as a fractition
20. I swear that body mass substitution question nearly caught me out - for part b I initially forgot the height had to be squared. Luckily I noticed afterwards and changed it, getting an answer somewhere in the 60s
