    Regarding the integral everyone seems to have struggled with: can you say what the exponent was (either of the integral or the curve)? (It's not legible on the attachment you posted).
    Curve is y=1/(x^2-1)^3/2. Rather nice integral after doing step for 6 months. Shame i didnt have time to finish that part couldve got 95/100. Oh well I shall live haha.

    So actual integral was "just" \displaystyle \int \dfrac{1}{(x^2-1)^3} \,dx?

    That should have been nice for everyone who did STEP III Q1 this year...

    last year the official MS was posted rather quickly. A few days i thinkz could the same happen this year?

    Yep. Lost 8 on that since didnt have time. Sorry i repeat this but it is annoying lol. Shud get 88 ish so still not too bad.
    There are a few ways to do it but would be interesting which way they wanted.

    Probably more than I'd have got. I hate AEA papers.

    But the limits were different and the form they wanted was also different iirc. So Q1 strategy was kind of long here.

    How come? How would you compare them in raw difficulty compared to a step I paper.

    70? TeeEm will probably have he best astimate as I haven no clue how hard the paper was. Challenging questions were the trig and last question. I dont think vectors was hard(easliy could have been in a C4 paper) i just made a mistake.

    How come?
    Basically because (due to lack of practice) I'm not very good at raw manipulation these days, and in my experience the AEA is much heavier on this than STEP. And there's stuff I don't really remember how to do - I can often wing it, but with STEP there's question choice so I can avoid the worst of it.

    I've always felt the difficulty between them is comparable, to the point where I think which you prefer pretty much depends on the individual.

    Well, it's not an identical question (the base case for Q1 being 1/(1+x^2) means you had an arctan term, here you'll get logs), but looking at the given result I'm reasonably sure it would come out to that fairly painlessly.

    Yh there was a 3 marker which was a page of raw algebra.

    I think AEA is one of those things which is a lot easier if you're doing it with your A-Levels (like I did) because a lot of the tricks or manipulation nuances are already familiar to you. That said, I think the AEA has been getting harder. I haven't tried the 2015 questions but they look slightly easier than normal at first glance.

    Less thinking, more algebra.

    Everyone reckon they got the 7 marks for clarity communication and presentation? I did a picture of a harry potter at the end of my paper is was well good.

    Hehe but not unfamiliar for Dfranklin . It was deceptively tricky I would say. The algebra was not nice. I used more paper then i did in step II where I had 6 solutions. And i did not finish, atleast everything I did was right hehe. Except for 1 part of a question .
