Exam Dates Friday 23rd June 2017 am - C4 - 90mins
Want an A* overall? You need to get 80% across the whole A-level and 180/200 in C3 and C4. The minimum requirement is to get 75/100 in C1, C2, your AS applied module and your A2 applied module. Then you'll need 180/200 across C3 and C4.
Before you ask, you don't need 90/100 in both, you need to average 90 in both - so 80/100 in C3 and 100/100 in C4 along with an A at AS will give you an A*.
Now you've got no excuse for saying you don't have any maths work to do! This would last a lifetime, but in the unlikely event you do run out of maths to do - buy some cheap secondhand textbooks off of Amazon and that should keep you going!
If anyone is interested in doing mathematics at university, follow this link: https://www.thestudentroom.co.uk/showthread.php?t=4775132 I have published my notes from year 1 and 2 from the UoBath. Granted not all courses are the same, but it will give you a rough idea of the stuff you might come across. If it looks confusing don't worry, it's just the notation but you'll get used to that.
I cant visualise this question, can someone explain which is correct and why? You get different answers for both.
Your first/left diagram is more correct, whereas the right one is just wrong.
It clearly states that "P lies on AB" not the other way round! This means that P has to lie somewhere in between AB. It also states that "AP = 3BP" which means the distance of AP is 3 times greater than the distance of BP. I have drawn a diagram below to show this...
You are actually wrong in saying that the second one is right! How can the second diagram satisfy the statement that "P lies on AB"? For P to lie on AB it must mean that it is somewhere on the line between points A and B. I have described this above.

The MS agrees with what he/she said, it's the 2nd one not the first. I think the key wording here is "P Lies on AB Produced". The wording of this question is a bit strange.

OMG really? That is a very weird question! Can you explain to me what the word "produced" means in this context? Does it just mean a line that is produced from extending off of the line AB?
Such a ridiculous question!
Also, I apologise for stating what you had said was wrong. This question is definitely misleading!
For questions thatt state something like "solve the differential equation" does that just mean find y=f(x) or a certain mentioned form? So as in, I have to separate the variables etc.

It means find an equation without any dy/dx's (by separation of variables), if you're asked to give it in a particular form, then obviously you should do that.

Yep, produced just means extend/continue a line. The wording is confusing :/
Hey was just wondering what's the difference between normal and 'R' papers?
R- Regional Papers. I believe that they are papers that you sit if you are doing the paper outside of the UK. I've heard that it's due to the time difference, but not entirely sure
When do we compare coefficients? I know when to use it when finding the numerators of partial fractions but other than that I'm never completely sure
We compare coefficients because when the number in front of the x^2 or x^3 will be the same as the value calculated from expanding the brackets, with the same x^2 or x^3. Make sense? its like working backwards, which is essentially what partial fraction is.

But what about examples besides partial fractions ?
when doing differential equations, can you always just work out the plus C at the end? if you make changes to the whole equation eg times by -3, can you just leave the +C as +C?
