    i got 2016 for the 10 billion one....
    cus it was 1.14 increase every year. the population was 7.23 billion in 2014 right? so i did log 7.23/10 divided by log 1.14 which gave me 2.475 years plus 2014 so i just wrote 2016.... is it right?

    for the interior angle one i got 45 i think but im not sure it its correct

    i hope paper 4 is easier....

    it was very hard paper 2
    i did over 21+ past papers and scored A in them but this paper was just outrageous.

    I barely had time and rushed the inequalties shading and wrote the x and y tables in pencil

    Where do you find unofficial mark schemes for other subjects?

    How many subjects are you taking this year? 21 past papers is hell of a revision.

    Log function in the calculator is outside of the syllabus for 0580 and the answer you got does not seem realistic :/

    I too used the log function to get the answer 2044. You're right logarithms aren't in the 0580 specifications. Couldn't even think of any other solution though.

    Do you remember what the mode value was from the question about finding 4 numbers given mean, median and mode?

    Atleast I hope you got the quadrilateral correct. I can't believe I never thought of a parallelogram. .-.

    Most people I know agree the answer to be 2043.

    The expected way was apparently to use the compound interest formula. I devised my own formula and got 2043, but the devised formula was the same as the CI formulae in the end.

    Well, 45 is defo correct. And I wouldn't bet on paper 4 being easier. Paper 4 is the hard paper, so better start practicing now 3:

    i did something like 68,77,77,78
    Close. I got 68,76,78,78

    78 was the mode in your variant, wasn't it?


    Either way, you're not the only one. I would do past papers so effortlessly and I was finding my self at odds with the paper. Weirdly though, I found the first 5 pages the most challenging as compared to the last 6 which were a piece of cake. I always assumed it'd be the other way round. On the bright side, we might have a low threshold DD

    did you know the interior angle polygon question and the second nth term question?
    If i remember, the answer to that is 45
