Really scared, I've definitely dropped about 30 marks on this paper I reckon I need about 65-70 UMS in C4 now for an A, what if the paper is really hard :frown:

Think positive, if C3 is hard then it's likely that they'll make C4 easier/standard.

What did everyone get for 10 b and c? I only had like 5 mins to do the entire question because I didn't think there was 10 questions!

lol the sudden panic attacks xD

So i totally didn't write tanA=sinA/cosA therefore cosA = sinA/p lol

The trend so far this year has been make stats hard, make mechanics easy, make core hard, so it'll probably be a tough c4 paper

I know I need to. It's just I've been so confident in Maths for the past 2 years and I would have loved to have smashed it today to put my mind at ease.

Damn, I feel really bad about being really confident about my mark in this...

Even if I did bad, I've still got next year to try again :wink:

How many marks for each of these answers? Could anyone care to help?

pretty please

1)c) cot(pheta-45) = 1/tan(pheta-45)

2)c) I stupidly only solved the answer for one of the values, which was In(3.5)

3)c) k>1 and k<-1 --> forgot to multiply it by 2 root 5

8)b) I made (cos A + sin A)/(cosA - sinA) = 1/2 ... then I made (cosA+ sinA = 1)

9)b) and c) ... for 9b I found du/dx=1 and dv/=1 but I used the product rule instead of the quotient rule so I got the answer wrong. For 9c I said k is negative so my wrong dy/dx will always be positive (I even subbed in two figures to back it up and I concluded that it was an increasing function)

So many stupid mistakes...and I know I am pushing my luck with those answers, but if I were get or 1 or even 2 more marks from those them I would feel more secure haha

For an A* is it 90 in c3 and 90 in c4 individually. ..or is it 180ums from both...like 85 in c3 and 95 in c4?

Aah so if I get about 85ums on this and at least 95ums on c4 and an 80 average over everything else....then that'll be an A*?....you've just made my day by telling me this :biggrin:

Does anyone know when the official grade boundaries come out? Is it the night before results day?

looking at arsey's answers I think I got around 65 on this paper, does anyone have an idea to what UMS roughly this would be? (I think I ****ed up big time on M1 so I need a rough guide for what I need in C4 for an A overall). I got 256 UMS last year

65/75 on C3 is normally about 87/100 UMS which is an a, but I think this year it'll be more like 90/100 UMS and a* due to low grade boundaries!

If I labeled the graphs with just the number of the point it crosses, rather than the co-ordinate, (e.g (3,0) ) will I still get the mark or will I get penalised?! :redface:

Hey guys i wrote (sqrt)20 instead of 2(sqrt)5.
The reason i wrote this is because is past papers they specifically wanted it as a whole surd so that's what i put as my answer. Would I drop marks for this or not?
