To Mirror EZY_FR's remarks,
Well done to all those who have got this far, and that statement is a true testament with this being my second visit to CTC for this program, albeit more prepared than last time.
One of my favourite quotes is "The phoenix must burn to emerge".
That's not to say you will fail, but getting to this stage is that next step on the ladder to success you and I so desire.
As for preparation for those of you concerned, CTC have a selection guide available on their website so i'd go and give that a read :-)
All the best
