Microfilter -
you sound like the kind of student that thinks all he has to do is pay the money and collect the licence.
OAT work very hard to maintain high standards in their Fair weather base and it tends to be poeple like you that focus on the 'minor' areas of weakness instead of just getting on with the task in hand. You wouldn't turn up for work with any airline un-shaven would you?
I speak from experience as I used to work for OAT in a previous life.
