For the binomial I put it up to x^3 cause im a retard instead of just x^2, how many marks do you think I would lose?
None, the mark scheme will just say ignore further terms, as long as up to x^2 is correct. Maybe max 1 mark but I dont see why they would

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
arsey (i see) you did well LOL

Hi please could you direct me to these markschemes?

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?

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!
5. Method for 7b?
also predication for the a boundary?
6. (Original post by C++)
Not enough sorry; despite being raw marks, and meaning the overall UMS score is higher, it does not amount to a 50UMS increase.
are you sure?

1) absolutely loads
8. Why does Arsey never drink at a party?

Cos it's illegal to drink and derive...
9. Would 64 for C3 and 72/73 for C4 be an A*?
10. My uni offer is AAA
If I get AA and a very high B, will they still accept me
11. 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? :/

Where???
13. 92 UMS C1
95 UMS C2
78 UMS S1

68 raw C3
69 raw C4
60 raw M2

Chance for A*?
14. c1 - 63
c2- 55
c3-52
c4-75
s1-68
m1-56

is that an A?
15. (Original post by rohan1811)
ahahahahahahahahahahahahh retard
umad bro?
16. C1 - 85 ums
C2 - 75 ums
S1 - 66 ums (Should have retaken this ffs)
C3 - 55/75
C4 - 60/75
M1 - 67/75

Bye bye A :'(
17. C1: 87ums
C2:87ums
C3:74ums
C4: 49/75 raw
S1: 83ums
M1: 91 UMS

Is an A likely?

Arsey once integrated a tortoise into a turtle.
I lol'd hard!
19. (Original post by LukeTownsend123)
I reckon it's more likely you've got an A* overall than not having one
Ye it's borderline isn't it
