CCEA A2 Maths C4 1st June 2012

Original post by North Irelandman

(In percentage raw marks to UMS) Off the top of my head:
C3 was 91 to 86
C1 was 87 to 80
M1 was 85 to 79 - resat on 14th May
C2 was 77 to 73 - resitting on Friday
C4 sat last Friday
M2 next Thursday

Need 480/600 for A
Currently 318/400

M1 was not great, could go up a few UMS at best
C4 was awful, probably around 62-76 depending on scaling

We get them given to us on a thin, very processed looking page that gives raw marks, ums marks and total available ums marks (100 in Maths, 88 or 111 in Physics for example), but you can work out the %s if you know what the paper is out of in raw marks (75 maths, 90 physics again for example). I'd say that's how the school receives your results, perhaps if you asked they'd give yours out?

I have heard S1 is a very "100%" type of maths paper, actually quite jealous we don't do it :frown:

The continuous distribution. Where you had to integrate then it asked you to find values for a and b :s-smilie:

Oh yes, you just integrated between a and 0 and set it equal to 0.25, same with b, instead it was 0.75. Then the IQ range was the difference of a and b :smile:

The S1 paper was quite good today I think, especially when compared to C3 and C4. Think I did the very first question wrong in terms of finding mid-points haha.

Although it felt like there were a lot of algebra style questions: finding a, b or p.. which I didn't see so much in the past papers.

Might have been 0.836? I think there's a S1 thread formed elsewhere, maybe we should relocate :tongue:

Struggled with the independent bit because I forgot all the little rules. Not sure if the probability was right before that because people were saying they needed a venn diagram and I just did it using addition rule etc..
Going to qub hopefully but not to do maths :smile:
