Thanks very much for your response, Nevilinio. I'm pleased you've told me to research partner airlines because it hasn't really been mentioned in what I've read so far. With the maths, are you required to solve equations and the like or pretty much just long multiplication/division etc?
Obviously you have to provide answers to the competence questions you are sent by e-mail, so do these form the basis for the answers you give when they discuss them in the interview, or are you expected to provide different examples? Is anyone aware whether it even takes that much to pass phase 1 (which I have done)?
