Since in the UK there is no formal GPL exam, at what point in time is a person considered a "pilot", and no longer a "student pilot" flying under the authorization of an instructor?
I would assume that's the earliest opportunity that a person could do a DI and sign off the aircraft by him/herself. Until then it would be the instructors responsibility.
If the BGA doesn't consider you a "pilot" until you achieve bronze, the point is moot, right?
