AQA Pure Mathematics A Level Unofficial Mark Scheme

Where does it say that?

I love mechanics , stats but core I always get stuck on the harder 10 markers and further differentiation and integration I lowkey think I scored around 40 marks on paper 1 but idk if grade boundaries will be low do I still have a shot at a B/A ? If i get Distinction* BB I still get into my uni of choice but today has made me feel bad.

Yp

for point of intersection why did i get 2 sets of coordinates :*((

n=500 for which question?

One of them was 0 but that couldn’t be possible because it would involve dividing by 0.... I think

That can't be right, the inverse function was root (2x - 1) which is invalid is x = 0. (1,1) was the answer.

Last year was 56% for an A for Paper 1

AQA have said themselves that the boundaries will be lower this year as a less able cohort (ie not all further maths geniuses who have rushed through a qualification in one year) is sitting.

is there a source on this?

Follow up question about dY/dX asked about the integral of e^-X(sinx) and how to represent it as ae^-X(cosx+sinx) i got a=-1/2

same

Sourced that info from my teacher, and it's also pretty logical. Obviously the grade boundaries will be lower for a cohort sitting an exam of similar difficulty when the cohort isn't entirely made up of further Maths geniuses doing an A level in one year, many of whom probably scored upwards of 80%+.

Just remember that although last year was only further maths students, they learnt the whole course in 1 year and probably had no revision time.

They’re also all very able. Think about all the dribbles that did it yesterday. Grade boundaries will shift down slightly but not by much

What you thinking ? 50 for an A?

Yeah again it's just practice, if you've got a good textbook to work from then you should just do the chapters in there. If not you've always got PhysicsMathsTutor and loads of other online resources.
Differentiation and integration do take a long time to master, and alot of the skill actually just comes from recognizing, then mixing and matching methods/ subbing values.
If you learn to recognise how formulas work, and know how stuff differentiates and integrates, you should be fine.
You could make a cheat sheet, that has all the integration and differentiation formulae, AND the products of differentiating certain values (e.g. e^2x > 2e^2x). This will make it easier and quicker for when you go through questions, as you'll have everything you need right next to you.
Good luck!
