AQA A2 Mathematics MPC3 Core 3 - Friday 5th June 2015 [Exam Discussion Thread]

I generally will do the paper in 1 hour 10 minutes in the real thing - I always take my time when it comes to it. I'll aim to spend 20+ mins storing my answers, but only if I know I've 100% answered them as fully as possible.

Don't wanna jeopardise my score for the sake of storing my answers haha.

I'll definitely need contributions from others.

I've got the C3/FP1 clash as well! I'll see what I can remember from C3, it shouldn't take me too long to do the paper unless something weird comes up.

Well if you cannot remember anything, I will help you out afterwards, but it will be 90 minutes after the exam ends! Don't think I am confident enough to do C4, depends how it goes!

I'm sure between the three of us we can come up with a fairly good mark scheme. I'll obviously do my best but I think we can all agree to not rush and just take as long as we need before thinking about noting answers down.

Yeah don't mess up the paper just to write a Mark Scheme, hoping there isn't anything ridiculous on it that I get stuck on for ages!

If all goes our way then the mark scheme will be fine to do. If not, it's not the end of the world as we'll probably get most of it down through discussion on the thread - shall I add it to the first post?

No a separate post should be made with the title specific to the Mark Scheme, TSR will probably catch on and link to it from there front page, thats what the did with mine!

I see. No worries. I'll aim to do that. I won't be out of the exam until around 11:05am though, so I'll be a little slow.

Do you get extra time?

In terms of differentiating using the chain rule (and product) could they ask us something like this. And also when intergrating trig terms such as y= sinxtanx, how would we know what is u and dv/dx.

This could possibly come up, it is in the spec after all! The latter would not come up though, the only integration by parts will have one term as $x$ or $x^2$

My teacher used examples like:

$\displaystyle \int e^{2x}sin{3x}\ dx$

Are these definitely too hard to come up?


Posted from TSR Mobile

The first part could come up. Out of curiosity is this what people make it to be?

Wasn't too confident on dealing with the ln term so I brought the power down.




Posted from TSR Mobile

Yes they are, one of the terms will either be $x$ (take this as u and use integration by parts once) or $x^2$ (take this as u and use integration by parts twice.

I see. Do you use the

U
L
A
T
E

rule?


Posted from TSR Mobile

I have heard people talk about it, but not actually sure what it is, care to inform me?

U is just to remind people it's when choosing U. Then follows the order of terms in which you choose U to be when integrating by parts.

L = logarithms
A = algebra
T = trigonometry
E = exponentials
