AQA A2 Mathematics MPC4 Core 4 - 9th June 2015 [Discussion & unofficial markscheme]

if this helps triggers anyone's memory
I know the last one was
-2 = z

and I think y was 1


(and Im taking a guess with x was 3 but this could be wrong

I just know the dot product looked something like

2 x _
-4 x (maybe 1) = -4
-6 x -2 = 12

so um using those 3 I got 59.1
which obviously is um close to 60
and it could also mean that those people saying 69.1 could be getting confused with 59.1

also..

did it say to the nearest degree or something?
because I remember I had a decimal place definitely

For 7c - if I wrote dr/dt = k/r instead of dr/dt = k/pir^2. How many marks would I get?

(I know I'll get none according to JackyDoyle4 and the examiners will most likely penalise me, scoring me 0UMS overall in this exam)

this jacky guy is such a prik...

lool funny thing is he could be trying to cover up his flop and make others feel bad

yeah i got the angle as 69.1. what ums do you think 62/75 will be on this? i need an A* for maths otherwise im screwed as I need an A* in maths to meet my offer :/

I'll be wondering why I failed my physics, then I'll remember that it was because I failed the exam on this Thursday because I was preoccupied with the lowest that the human race has to offer.

Also, nobody says "lexis", we're not doing an English essay here.

I really need an A* too

and I was sick on C3
I ended up doing mistakes that I'd practised many times before
for example on the graphs and I even missed the secx by accident..

I literally didn't see it and integrated xsqrt5 or something along those lines.
that's why I really need 100% for me to have more than a ._ chance of an A*

anyway

um according to last year's boundaries
your mark of 62 = 96% UMS



depending on how you did in c3
you have a good chance
basically, you need to have gotten at least 84%

um that's also depending on if this year's boundaries are similar to last years

I guess last year wasn't too hard either so I thought it would be similar

Last year was 54 = 80
59 = 90
64 = 100

I think it might be lower this year for some weird reason, maybe 52 for 80 and 55 for 90
Well I'm hoping so anyway, even though it didn't find the paper ok, it would be better if it was easier to get an A*

can anyone explain why Q6 is 11/8, i have -5/8 and cannot figure out the mistake

it wont be lower mate.

Last year had a question that was totally inaccessible. This year did not Hence much higher boundaries

Well not everyone found this paper easy, many people found it rather challenging. Here's to just hoping that it's lower so it makes it easier to get the full UMS
