Edexcel C1 16 May 2012 Post Exam Thread - Paper and Solutions in the FIRST POSTC1 May 2012
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...

(the second one contains loads of past papers, model solutions, etc)
Good luck tomorrow.

Re: C1 May 2012 Post Exam Thread - Paper and Solutions in the FIRST POSTAgreed - am a bit gutted as I thought C1 was a chance to get full UMS but know for a fact I've missed that.(Original post by The Assassin)
Ok here we go... I thought that paper was rather tricky so I don't really know what to expect. -
