Edexcel C1 13th May 2015 *official thread*

I sat this paper last week and got it back today. I was wondering if anybody had the mark scheme so that i can make corrections? Thanks.

How did you find the paper?
A lot of people said this paper was extremely hard, however, I personally think it was a lot easier than most of the other papers... there was only one weird indices questions which was simple if you had done logs.
The mark schemes are locked, but here are the model solutions by Arsey
