Congrats, Flock - now the wonderful wait for the CAA to process your licence!
And Fred,
How ethical is it to change flying schools if one isn't happy (for whatever reason).
How ethical? You're paying £100+ an hour to learn to fly (and down here that's a very big '+'). At the very least tell them that you're not happy and give them a chance to do something about it. If you're still not happy, go elsewhere.
