    I'm obviously not going to upload any solutions until you give the go-ahead, but could I perhaps do the solutions for STEP II questions 6, 13 and that [redacted] one?
    Sure, sounds good. You can post it up at 9 a.m tomorrow morning.

    Nice solutions guys, just wondering where I can find the paper? There were photos on here yesterday but can't find them now? thanks

    I've posted the link to the pdf a few times on the main thread, you can go look 'em up there.

    It's here (might be useful if it was added to the OP of this thread).

    Do we get the go-ahead now? Double checking

    How did you do?
    I got Q1,Q3,Q7 completely perfect. And Q8 right till the very last approximation so around 76 marks there. Then I had half the DE half the binomial and first part of the factorisation. So Im sitting on 90-95 ish.
    What the **** was siklos thinking. He puts 1 geometry 1 vectors every year which gave me S grades and this year he decided to put no geometry and vectors(everybody else probably liked this) but no geometry and vectors really threw me off wudve given me a solid 100+ score 😔.

    There may be other ways to do the very last part but I couldn't find any that worked. I tried a t sub but it required use of tan(pi/8) which is.. Ugly.

    Here are (my) solutions to questions 6, 13, and the summation one (done from memory, I haven't seen the question paper since the exam, so some minor details missing that I'll add in later)

    Edit: For Question 6 8, since I have the value for E, I can now complete it:
    \sum_{r=1}^{ \infinity } r^{-4} ~= \dfrac{8}{5} -4(1.645) + 4(1+\dfrac{1}{4}) +(1 + \dfrac{1}{16} ) = 1.6 - 6.58 + 4 + 1 + 1 + 0.0625 = 1.0825 ~= 1.08

    Any idea how the marks on Q7 will be divided? I was thinking 3,3,4,5,5 for parts 0-4... Also on Q6 how many marks do you think the last part will be worth?

    what was the exact question from the last part, I got a nice answer which I'll post just I can't remember the exact question?

    Literally just IBP on (III) solves it immediately

    I have a nice answer aswell. It was integral 0 to pi/4 of x/(cosx)(cosx+sinx)
    I am saying what other ways were there other then mine cause First i tried t sub then after divide top bottom by cos^2(x) giving a nice solution.

    I think I did reasonably well. I think I got 6 fairly solid fulls, and 1 not-so-solid full (question 1 - I hate graph sketching!) as backup. Possibly around 90-100?

    I noticed the lack of geometry and vectors - I was quite pleased tbh - but we'll probably get them in STEP III

    Also, the stats question I did was amazingly simple. An absolute gift.

    Still, don't you only need a 1? Or is your offer S,1?

    Here are (my) solutions to questions 6, 13, and the summation one (done from memory, I haven't seen the question paper since the exam, so some minor details missing that I'll add in later)
    Need S,1. Will be close in II.

    I thought the last part was something like ln(1+tanx) ? sorry I have a rubbish memory lol
