I'm specifically studying Maths under Edexcel, and with a few days left until C1, and a week until C2, I haven't really started looking at the past papers for those specifically yet. So to not waste time attempting the easy papers, what are the hardest C1 and C2 papers you've come across? State the year and month and exam board (doesn't have to be limited to Edexcel).
Note: please don't give away questions, your word is enough for me to take a look
Thanks in advance.
