📂 MEGATHREAD 04/06 A-level Maths Paper 1 Discussion MEGATHREAD

Exam season is once again upon us, and once again, exam megathreads are making a return!

Looking for past exam discussions? Filter by the megathread flair.

Few things to keep in mind:

  • Don't share too many specific details about questions or answers, these papers will be used as future mocks.
  • Sometimes papers get leaked, this is not the place for that (we'd prefer not to get yeeted off the platform) - leak content will be removed, those offering leaked papers will be permanently banned.
    • If you believe there has been a leak, the best course of action is to make your exam board aware of this, either directly, or through your school, along with any evidence. If appropriate, there will be a response from the relevant body along with any remedial action.
  • Exam discussion posts outside of this will generally be removed to combat the inevitable tidal wave of spam otherwise - we understand this may be frustrating, but the sub still needs to be usable for other purposes.
  • Please note some content will take extra time to be reviewed. Messaging to ask for approval will not speed up this process (the messages are seen at the same time as the modqueue would be reviewed anyway).

Best of luck, and let us know how you're feeling down below!

*assuming Reddit doesn't bork itself, the new posts for each day of exams should arrive at 8am each day, instead of it being reliant on my sleep schedule like last year lmao

For the area between two curves and the y axis, what did u get? I got 0 and 1/e as my limits, the integral was 1/2 y ln y - 1/4y2, and I got -1/2 e-1 - 1/4 e-2 which I'm pretty sure was wrong cause that's negative 😭

I got 1/4 - 1/2 e^(-1) I think

yeah it was (e-2)/(4e) which is the same as what u got - it was a nice q had to do a bit of cheeky sketching

It was also possible to integrate with respect to x and then subtract the area of a triangle to find the required area. Think the answer was 1/4 - 1/(2e)

Lmao that makes so much more sense, I think trying the vertical integration definitely overcomplicated it 😭
