Edexcel A2 C4 Mathematics June 2015 - Official Thread

1) 90% Avg in C3 and C4
2) 480 (or more) in all your maths modules combined

Is this the same for if you're doing further pure maths?

So if I got 90% avg in C3 and C4 but totally flopped in FP2, but still managed to get 80% overall over C1 C2 FP1 and FP2 would I still get the A*?

I'm not sure you should have been having to integrate that in the first place in C4. Was there a previous part to the question?

Ahh damn but ty, for part c) did you get 5/3?

I only realised how to do it within like 30 seconds of the exam ending so I ended up only writing down the method and multiplying out fractions. Didn't have enough time to calculate it but oh well

How do you even do question 6 when it was integrate by substitution? :s-smilie:

We said that the radius of the cone was 2 when it was actually 9 😢

radius of cone was 9-that point you 2-1/ln3

1. It didn't say what number the population started at, it could have started at 3999

2. With questions like these you always use radians...

it said when t=0, P=3 ...

I doubt it. 0.2 yrs for the animals to reach a population of "4000"?! It has to be in degrees so u get 27yrs. C'mon lets be realistic. Do u think humans can produce 4000 offspring in 73 days? (0.2 yrs)

but if you put 0.473 back into the original equation, you get a population 4000 so it's not 27 years sorry to disappoint :l

My answers, judging by other people's opinions I think they're right:

Agree. Can't remember what I put for 8b) but I think it was that ^

Paper was Alright not sure its good enough though to compensate for C3 and bring it up to an A*.
Thank you God for the easy vector questions.
I noticed P was in thousands in the last minute of the paper. I got a dodgy answer for the final question. When you guys calculate the Volume of the cone 1/3 (pi) r²h is h=9 and r= ln3?

That's what I got :smile:

Same... C3 was a bit off this year, I was so happy when I got to the easy vector question so early in the paper.
When I finished I was like "this was too easy" so I flicked through the paper and made sure I had answered all the questions.
