    Overall I think this was a very easy paper.


    Q1 Binomial Expansion


    Standard and no tricky b)




    Q2 Logs


    Standard, very easy




    Q3 Circles


    I expected a rearranging into circle form, the rest of the question was very easy, part d) was a joke




    Q4 Factor Theorem


    Very easy




    Q5 Area under a graph by integration


    Slightly harder than normal as trapeZia often cause problems




    Q6 Trig


    I thought this was pretty easy but I understand it has caused quite a few problems




    Q7 Trapezium rule


    Joke




    Q8 Trig


    Pretty standard, lots of frameworking.




    Q9 Geometric series


    I hope you learnt the proof.... rest of the question was straight forward.






    I think the boundaries will be really high


    Last few June boundaries were 62, 62, 53, 63, 59, 67 for 80ums


    I will guess at


    100ums - 75
    90ums - 70
    80ums - 65
    70ums - 57
    60ums - 50
    50ums - 43
    40ums - 36


    This thread will be locked at somepoint and then unlocked at midnight following the Core 2 examination. I will upload the paper and my solutions to this post.

    I will do my best to answer questions about the paper but please try to read the thread first so that I am not answering the same questions lots of times.Here are some links to previous D1 threads, they are worth a read and you will see what the common errors were...

    The exam was reasonable the cast question was quite unusual and so was the differentiation bit but all the rest of the questions were alright

    I swear someone predicted that on the C2 thread (might have been Arsey) - I went and learnt it as well luckily enough...
