Prior to the first group exercise, you'll have to briefly introduce yourself... You'll remain seated around a table and will talk about you.. Who you are, where you come from, your education, your hobbies and most of all WHY you are here today, why you want to be a pilot...
Think of it the day before, it musn't be to long as it's very unformal... But don't forget that it is your first contact with your assessors... So keep smiling and be happy..
