Reasonable paper with plenty of straight forward marks and some more challenging ones.
Q1 – Integration – standard question. Q2 – Indices – more complicated than normal, but relatively easy. Q3 – Surds – standard. Q4 – Differentiation – Quite easy. Q5 – Recurrence relations – fairly standard apart from an unusual inequality in the final part. Q6 – Arithmetic sequences and series – a) pretty easy b) not really that hard either Q7 – Integration and coordinate geometry – standard Q8 – Quadratics – The negative aspect definitely makes it harder than standard, potentially a bloodbath this one. Q9 – Coordinate geometry – reasonable a-d) but understanding e) was not easy, extreme bloodbath, but only 3 marks Q10 – Very easy transforming graphs.
Last 3 June boundaries were 58/59/55 for 80 UMS. I would be surprised if these boundaries are very different from those last summer. I am going to guess 73 = 100ums 66 – 90ums 59 – 80ums 52 – 70ums 45 – 60ums 38 – 50ums 31 – 40ums
This thread will be locked at somepoint and then unlocked at midnight following the Core 1 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 C1 threads, they are worth a read and you will see what the common errors were...
