I don't think I'm going to get the answers I've been seeking here, or from the majority of the Schools. You are probably right; there are more important things to worry about. Ultimately, the only first time passes I'm interested in are my own! For the record, I've recieved an e-mail that points out that there is a difference between first series passes and first time passes for flight tests, but there is only one way of measuring ground tests. And it is not necessary to do a degree if you do your training with London Guildhall/Stapleford.
Thanks for all those who have taken the time to respond constructively to my questions. Time for me to shut up!
