Edexcel A2 C4 Mathematics June 2015 - Official Thread Watch

1. Anyone have an idea what these marks would relate to in UMS roughly?
65 in m1
42 in c3
58 in c4
2. (Original post by StarBizarre)
omg those are my predictions too! I do hope it's an A*
I hope so!
3. Damn... Q8 I put the wrong limit and get the wrong x intercept but I put the correct intergtal.... and the gradient is correct....
Q3c I get the integral correct but i probably lose mark for accuracy
Q5a the dy/dx I just give the expression... forgot to sub 2
Q7c i used degree.....

how much did i lose...still possible to get 90UMS?

Probably 2 M1s and an A1 for Q8, A1 (as you said) for 3c, probably M1A1 for 5a and A1 for 7c - so 7 marks lost I would say.

thank you... also is there a mark (M1) for trying to subtract the wrong integral answer to the wrong cone volume...lol? and did you accounted it?

Damn I also got exactly 249 UMS in AS. I got about 52 in M1, 55/56 in C3 and 65 in C4.

I think what you got should get you an A barely.What grade do you need? I really need an A..
Hi 5 haha! My offers are AAA so a B is like a fail right now I hope you get that A though!
7. last year 259UMS

this year D1 -65
C3 - 70
C4 -45
What grade do you think this is!?

I would have thought about 86 UMS for D1, 96 UMS for C3 and maybe 60 UMS for C4. So should be an A overall
10. For question 8 I got the volume of the main function right but got the volume of the cone wrong, how many marks would I drop?
11. I think I got 73-74 / 75 in this paper , what UMS am i looking at?
12. Having got 100% UMS in C3, do I still have a chance of an A* with a mark of around 62/75 in C4?

Obviously? Like have you even looked at past grade boundaries? smh

The answer was 13pi/ln3, I think you forgot to take away the volume of the cone.
Ah no what i meant was just integrating the curve (without taking away the volume of the cone) does it give you a value of 40pi/ln(3) ?
15. Just wondering if this is good enough for an A* overall??
•96 UMS C1
•97 UMS C2
•91 UMS S1
•72 UMS S2
•94-95 UMS C3 - prediction
•88-90 UMS C4 - prediction

Yes, the curve will give you a volume of 40pi / ln3 from which the cone's volme has to be substracted.

For an A* all you need is 90 + average in C3/C4, the rest don't make a difference so yes I'm sure you'll have an A* (You don't need over 90 in both C3 and C4 just an average greater than or equal to 90)
19. Would you lose marks for not labelling the axis y and x for graph sketching? I've got a bad feeling that I didn't.
20. I think I got 66 in c3 and 70 in c4, do you think that will be enough for an a*? I think it will be right on the border.
