    i think there’s a problem for Math paper 2, question 6 (iv), there reliability of the the prediction should be unreliable due to extrapolation, where x=2010 is out of the data set used to derive the equation

  • .. Says:

    there seems to be an error on the DE question for 4ii shouldnt it be multiply both sides by -0.02?

  • alvlstudent Says:

    DE for question 4(ii), integration should lead to both sides dividing by -50 instead of -0.02

    Thanks for pointing out the mistakes, I will upload a final copy with all the changes soon 🙂

    hey, i think for 8iii, it should be 480
    we set out 4 slots for the consonants ie _ _ _ _ = 4!
    then we slot the vowels into the spaces in btw, which is 5P4, then divide the 3 repeated E
    => 4!*5P4/3!=480

    not sure whether it sounds logical to you but it sounds logical to me… 🙂

  • Wei Jie Says:

    Me: There’s something you may have missed out. If we were to choose any five slots, we may end up with two consonants next to each other.

    Example –

    [1] L [2] V [3] T [4] D [5]

    When we choose the slots 1, 2, 4 and 5, V will be next to T, such as ELEVTADE is invalid. Also, if we choose the slots 1, 3, 4, 5, such as ELVETEDA is invalid since L is next to V.

    Therefore, we can only choose either 1, 2, 3, 4 or 2, 3, 4, 5. By this approach, it will be 4!*2*4!/3!

    Hope this clarifies 🙂
