Just sat my stage 1 at 16.00 - ATC paper went fine and of the 40ish of us, about 20 tops went through to the next 2 papers. The diagramming test was ok, although I didn't finish it I did think all those I answered were correct. The cubes like people have mentioned were very tough, a lot of people said it was difficult.
I wish everyone else the best on their tests and do revise and prepare as much as you can.
