    Update: I finished a mock yesterday and also have tried STEP 3 1998. I am still not sure whether to write STEP 3 or not as I find it extremely difficult.

    How much would you cut for not showing that x=4 is invalid and x=0 is invalid in Q 1 STEP 2 2004(and writing X=4,1,0 for all three) ? and how much mark for solving part (i) of Q8 ???

    4/5 marks. IIRC, x=0, 1, 4 are solutions to the first part. x=1,4 or 0,1 are solutions to the second one and x=0,1 or 1,4 (basically the opposite of the second one) are the solutions for the third one.

    and how much mark for solving part (i) of Q8 ???
    4 marks.

    Give yourself 5 marks for Q8(i), I suppose.

    STEP 2 2004 Mock 98/120 S

    A very nice paper. And I understood the significance of going thoroughly through each question before attempting it. Choice of question really matters.

    Q1, 15/20 I thought this was a very easy question but in the end I lost most marks on this. Didnt realize that x=4,0 are invalid for some cases.

    Q2, 19/20 Drew the graph but forgot the asymptote. At first the question seemed very complex and hard to understand but once u get it its fine.

    Q3, 20/20 I spent most time on this question apparently because i was confused whether x=2 is a stationary point or not. (As the second deri was zero but also the third deri)

    Q5,20/20 Pretty tricky imho. And im still not satisfied with substituting x inplace of t(though i just did it in the mock)

    Q8 4/20

    Q11, 20/20 I thought power question was easy but after the mock i realised that q9 was easier and quicker to do.

    If the first derivative is zero, then the point is a stationary point. These stationary points could be any of (i) a maximum (ii) a minimum (iii) an inflection point. If the second derivative is zero, then it is an inflection point unless the third derivative is also zero. In which case you need to investigate signs for the nature of the stationary point.

    sorry i was confused whether its a min point or a point of inflexion. Lokking at the dy/dx(after and before x=2) told me that it should be a min point but looking at the second deri told me it might be an point of inflexion but the third deri told me its not so. So i thought i went wrong with the algebra, Thnx m8

    Yes, that's what I'm saying. The second derivative being zero means it's a point of inflection unless the third derivative also vanishes at that point. In which case the second derivative reveals nothing about the nature of the point and you should only look at the first derivative.

    STEP II MOCK 2005 91/120 S
    A not bad paper.

    Q1, I took a bit time to figure out P(x) was. Its a pretty simple Idea but never occured to me for the first 20 min
    20/20
    Q2, I thought this was easy and it did look very easy so i gave it a go but lost marks on the only if part(iii). I couldnt understand what the question meant and i thought they were repeating what they said in part(ii). 16/20
    Q3, Very straightforward Integration 20/20
    Q4, I love arctans they are cool. 20/20
    Q8, First two parts were fine but i messed up the last part. Instead of drawing the two graphs(reflexion on x axis) in one graph i drew them on seperate graphs. But I showed that the graphs approach plus and minus \sqrt (3) tho i think im being too kind to myself. 15/20

    STEP 1 2008 90/120 S
    Was expecting a bit higher but I found this to be a pretty tough paper. Well anyway I am gonna revise FP3 and some FP2 today and I will try to tackle STEP 3 2000. Wish me luck
