    The bit of code
    TimeSpent DIV 60 + 1 * HourlyRate + CostOfGoods
    Timespent DIV 60 will return a rounded DOWN value - this is how DIV works. It rounds down to the nearest integer. Adding 1 immediately afterwards simulates the rounding up.
    For that bit I put an if statement:
    If TimeSpent MOD 60 = 0
    _Without the +1
    Else
    _With the +1
    End If

    Just to be safe!

    I did that, but I did 1+1= 2, 2 * 15= 30

    30 + 100= 130

    Did you not have to add the 1 before multiplying the HourlyRate?
    No because using BIDMAS in the code. You have correct logic but because it's a logic error with the way the code is written.

    That's a shame but don't worry, you will still pick up around 2 marks out of 6 I assume as long as your method was appropiate.

    I can't remember the grade boundaries for F452 but I know they are generally higher than F451.

    The january 2012 paper grade boundaries were as follows: (Raw mark)
    A - 75
    B - 68
    C - 62
    D - 56
    E - 50

    I'd say this paper was easier although a lot of people seemed to have messed up the recusion part/record file question/array question when I spoke outside the exam hall so I can;t be sure what the grade boundaries for this paper will be.
    Last Year an A = 80. I got 78. So Lets Hope its lower.

    Yeah spoke to my dad afterwards and he said to me about why I had to do the division and multiplication before adding And if I had just put it all in one go into my calculator I would of had the right answer Think it was a 3 mark question, so as you had to show your workings out I think I may hopefully get 2 marks.

    Does anyone know if theres an 'unofficial' mark scheme for this paper yet? I'd like to try work out what I got marks for.
