You've received an invitation already?!
I was in the 2 o'clock group too, haven't received an email yet which would appear to be bad news
I also found the 1st paper to be fairly easy, and like a lot of others i was surprised to see that more than half didn't get through.
Answered 42/50 diagramming, pretty sure I got at least about 36 of these right.
the cubes - 1st 15 questions were pretty good and I was flying. Then it got hard, only got to question 30/40 when the buzzer went.
It was a good day, good learning experience but the lack of email would suggest I didnt get through. Good luck to everyone who did get through and those still to sit stage 1.
Any questions anyone has about the day who hasn't sat it yet just PM me.
