The bloke who did mine told me it was OK at the end and I received the certificate by post a day or two later. Don't then be a plonker like I was and leave it in a jacket pocket at home on the glorious summer day when your QFI decides that you are fit-solo and asks to see the chit. Nowadays my certificate sits looking rather crumpled in the lovely small brown folder those nice people at Gatwick gave me some months later.
