and now the DOs!
Do smile It makes a difference and makes you feel better
Do dress smartly but comfortably.
Do ask to be excused if you need to loo, at whatever stage! Again, you need to be comfortable, and sitting cross-legged with a bladder that’s about to burst is neither comfortable nor good for you.
Do take a breath. This sounds really obvious, but I have often waffled due to not pausing and thinking about an answer properly.
Do say if you don’t understand a question, and ask for further clarification
Hope this helps
VERY BEST OF LUCK and let us know how it goes!
