Hey I did 52 too. Wanna ask one question, what did you get for % uncertainty? mine was 2.4%
Mine was 7%, but I've talked to some of my friends, and the my answer is definitely wrong.
falafail, my paper 4 was actually abysmal. I couldn't finish it. The time ran out before I finished the paper, and I have definitely missed A LOT of points.
I did say on some of the threads that the questions were not really challenging, but I couldn't finish. I think either you mistake me for someone else or there's a misunderstanding.
By the way, anyone knows why there are more takers of P52 compared to P51 in these forums? Are the papers exclusive to certain regions?
