I'll edit in solutions in this post if I have a spare 30 mins tomorrow (i.e. if it rains and athletics is cancelled).

(My initial impression is that it looks pretty standard, I can spot a few things that might trip up candidates though).

I also got 2 as dy/dx :smile: for the parametric question I think:smile: it made sense to me in the exam and your workings out make sense also. I doubted myself after the exam as a lot of people got a fraction

I just checked the WJEC raw UMS site;
https://www.wjecservices.co.uk/MarkToUMS/default.aspx?l=en

The boundaries look very generous!

June 2013 / Jan 2014 (raw marks)

A* 068 / 064
A 062 / 057
B 054 / 050
C 047 / 043
D 040 / 036
E 033 / 029
U 000 / 000

I am very surprised by that, yet that has boosted my confidence for tomorrows results!
Really wish I'd sat this now :frown:
*fingers crossed*
Got an A in the end :smile: good luck to anyone else who hasn't had theirs yet!

Unless someone took it out of the exam hall, only centres have access to that paper at the moment.
