@ziphus
you will be scored on the clarity of your speech, how often you contribute, the quality of your contributions (i.e. don't just spout rubbish to be seen talking)
and how well you work as a team player (i.e. do you make other people feel heard, do you discredit the ideas of others)
the key is to contribute, but don't overdo it, speak clearly, know about the aviation industry (because the exercises will be aviation related) and make sure if you disagree
with what someone has said (shows individuality, but don't do it all the time) to add a PERSONALLY... or IN MY OPINION... or THAT'S A GOOD POINT BUT... before you make you're point. even if you know for a fact what they're saying is wrong, you've got to go
about it in a professional manner.
you get the idea.
