Unofficial AQA Pure Core 4 Mark scheme 15.06.2010

The last part of the vector equation, I worked out the equation of the line that C would be on - but got really dodgy answers after that because im useless at vectors.

Do you reckon I will still get a mark for working out the line equation or have I lost all 4 marks?
Thanks.

they don't come better than balliol that is fairly epic. fingers firmly crossed that a reading list doesn't find it's way through my door. lengthy i imagine?

(3,-1,3), (-1,-1,1)

Thanks , er mines 5 books but when 3 are entitled just 'organic chemistry', 'inorganic chemistry', and 'physical chemistry' you know they're gonna be pretty damn huge

Yeah, we got them, they're in the mark scheme. I mean the rest of the vector question, like point P and what vector AB was?

It wasn't that bad, I just had a really prolonged dense moment (1hr and a half to be precise XD). I made so many stupid mistakes and on the 'hardest question' I got it wrong because I forgot how to differnetiate XD.

Thanks, though the offer was A*AA, it was in F maths, Physics and chemistry.
So it doesn't really matter how I did today. Today was just for fun...

EDIT: You were in the Cambridge thread at one point, I swear. Did you get an offer?

i suspect they won't be the sort of thing that can be completed in one summer's toilet trips :P

I reckon you'll get a couple of marks for doing that, what else are the 4 marks going to be for?

Haha I wish, so what A-levels do you do?

biology, chemistry and maths all with AQA. I also did French last year. how about you? do you do chemistry with AQA? btw do you know if all the college send out reading lists for chemistry at oxford?

Hey, how did anyone get x=2 on the implicit differentiation question? I did x^3x1+cos(pix1)=7 => x^3-1=7 => x^3=8 so I got x as 2root2

I do maths on AQA but physics and chemistry on OCR. I did Classics last year. I have no idea who gets reading lists, I wasn't even expecting mine today lol. So what type of school did you go to and where else did you apply?

I figured |CP|=|AB|
|AB| was root 13

I worked out C and took it away from P

Then I got something like

(5x^2-2x+6)^1/2=root13
square both sides

5x^2-2x+6-13=0
5x^2-2x-7=0

x was 7/5 and -1

So put that into the (x,y,z) coordinates of the C and I got something involving 19/5, -1, 17/5 in the first one and no fractions for the second point.

got you, i was wondering so as to possibly share the pain of AQA chemistry and it's horrible lack of past papers for this module.

as for the reading lists i only ask because my gf is doing chemistry at oxford too so i wanted to know if she would be subjected to that as well :P

i went to a state school and college, doubt you'll know it's not well known. you??

i applied to bristol, Leeds and king's College London but i only get corpus and KCL, same to you?

Oh sorry, my head of science is obssessed with practicals so chose OCR Salters which is a really practical course. AQA is really different as well I think :/

Cool that your gf is going to Oxford, what college is she going to?

I go to a state school as well, my school came below average for my year .

I applied to Oxford, Imperial, Durham and York and got offers for all 4 of them

for 8d, I put 15.403 (to 3sf)
