Good luck Craic, I hope it will work out for you!!!!
I'm going to an assesment day at the end of the month in london and was wondering the same, but for me it will be the first time with EK so I haven't got a clue of what's going to happen!!
I also wonder if they have the same group exercises etc for everybody in the world or if they have different ones in different countries
Anyway, I am sorry I cannot be of any help, but I can wish you good luck and will keep my fingers crossed for you!!
Ciao
