Did you know all of the answers to the questions? What happens if they don't let you have a passport?
I'm really worried because we've booked to go away for a weekend, dp has never had a passport so he went to an interview, he's just come out and said he doesn't think it went very well, he didn't know the answers to some of the questions things like his mum's dob, her birthday, the age of the lady who signed his photo etc
