Edexcel A2 C4 Mathematics June 2015 - Official Thread

Why are people waiting for arsey there are already 2 fully worked solutions available

I got 256 UMS at AS

needed 224 to meet my offer
I reckon I got
75 - D1
73- C3
71 - C4

Missing out by a few UMS.. life is freaking great ! ffs
All my effort in AS to do no revision in A2 .. i am a retard

I have a few questions:
1) how many marks do I lose if I found K as 2 and continued so I got the area as half? Out of the total 8 marks of the question.
2) For the differential equation I found c correctly but at the end I couldn't get the final answer they wanted even doe part A was right. How many marks would I lose out of the 7
3) for the years question how many marks do I lose if I did the question in degrees?
4) for the vector question how many marks do I get (if any) if I found the position vector of B for the shortest distance?
5) for the cone question, do you get one mark for writing V=pi integral of y2? Also due to a lack of time I went to write what I would do instead of doing it, but I wrote the radius will be 9 for the cone et and you do integral until 2 minus the volume of cone from Q to P?

Not enough sorry; despite being raw marks, and meaning the overall UMS score is higher, it does not amount to a 50UMS increase.

1) Is this on question 6? if so not sure because might affect the marks for the previous section too.
2) what is c? there was no part c to that question and they didn't ask for any constants.
3) not more than 2 since that only affected the would have affected the last 3 marks. On past papers I think they didn't always dock the same number of marks for getting the numbers correct so difficult to say 1 or 2 lost there.
4) Finding the position vector of B was the first step to getting the right answer so you would most likely get a mark for it.
5)you'll get a maximum of 2 marks for that section I expect.

Hope that helps, it's obviously nothing definite though!

Arsey once integrated a tortoise into a turtle.

I reckon it's more likely you've got an A* overall than not having one

92 UMS C1
95 UMS C2
78 UMS S1

68 raw C3
69 raw C4
60 raw M2

Chance for A*?

If I got 66 in c3 and 70 in this one, would that be enough for an A*. I'm thinking an A* in c3 will be 67 and c4 would be 68 so I think I might scrape it. Or am I deluded? :/
