    You probably interpreted x^2 as (the total of x)^2 rather than the correct interpretation as (x^2 + x^2 + x^2 + x^2 etc.). I made this mistake at first but then realized where I went wrong after 10 minutes attempting to solve the issue 😆

    I think it was alright, grade boundaries should be between 76-78 I think.
    Why between 76-78?

    You do seasonal variation for the 3 quarter 1's add them up and divide by 3 and add it on
    The seasonal variation was - something and then add it on
