Exactly the same as you. Scraped an A* in the mock (59/80, GB was 57) but found this so so difficult and I'm just praying I didn't get a B because the boundaries are always so close. I genuinely couldn't even understand what article 1 was about which has never happened before, and I completely messed up section B because I had no time What was it about it that you found difficult?
With question 5 even though they asked us to write a letter about something that pushed us to our limits, I felt I wrote more of a story by accident. Also I just suck at question 4 but this time I did finish it, which is an achievement I guess
