All the best Abigail, it sounds like you have done your prep - just keep calm, do your best and like Chloe says knock 'em dead.

An interview is all about selling yourself, a lot of people forget that. If they don't ask the questions you want to answer make sure that you give the additional info later when they you have the opportunity to add something. I once went on a 'springboard' course for women, they told us that if you have a man and a woman going for the same job and they have similar skills the man will (generally) sell himself at a higher level than the woman. There is nothing wrong with selling yourself - confidence is key - you can do it!
