You needed to do 54 minus 108/5 which would give you 162/5 or 32.4
Thats what I got, i always struggle with that question

Hi all, im currently studying A2. Ive heard a mixture of how people found the paper in my college. 90% of people were talking about that cylinder qs,
if you remember any of the questions, im here if you want me to give you an answer
I would just like to clarify I put 648/30 as the answer to the intergation between two points which is the same as 108/5

Are you sure you are right??? Most of your answers match mine apart from 1c,3bi and bii
What did you get for 1c? I got some horrible looking fractions
4. Anyone do Edexcel?

I got 54 for the area of the trapezium so 270/5-108/5=162/5

was it a trapezium or triangle ???
It was a trapezium haha

Yeah don't worry, if 648/30 is the right value youll still get the marks

Did you say your line went through/cut the origin and touched x=3 only, because if you did I did that that aswell.
x^2(x-3) there is a repeating root at x = 0, and it passes through x = 3
so it touches x = 0 not goes through.
9. Pretty sure Q6a (i)(ii) was only worth a total of 5 marks, also didn't mention n=7 for Q2 will I lose a mark?
10. Well I did a load of past papers for core 1, all had seven questions. Got to the exam and left without doing question 8 so nobody will have done as bad as me
11. *turns to the cylinder question page*

12. For the circle question did it say to write the radius in the form n root something because I have just read that the equation was in the form (x-a)^2 + (y-b)^2 = d which would mean that the diameter was 50 so the radius would just be 25?

14. What sort of UMS do you guys reckon 67 will be?

I also think the OP has written the answer to 8a incorrectly as I remember it being 13-k or k-13 (can't remember which of the two was negative anymore
It should be ...+ 13 - k =0

A(9,-4)

Number of marks per question don't really matter that much and as for the n=7 if you'd bothered to look at any page of this thread you'd see the answer (spoiler: no, you don't lose a mark if you don't say it).

I used simultaneous equations for line AB and AC.
You multiply by 2 and 3 then get 19y=-76 or something like that meaning y = -4

Somewhere in the 90's I'd say, impossible to say where exactly.

That's it, cheers.

Personally I would say that marks per question matter. People who are on this thread obviously are trying to see how many marks they have lost. If the marks for each question are wrong there is no point in creating the mark scheme.

Hmm yes I hope so! Thanks
