Now that's an interesting question for me.
I went to a boarding school in the 60's where riding was part of the coarse and i learnt to ride there.after a year the instructer (Headmistress's daughter,ex army very strict)asked if we thought we were good enough to go up a class.
That's a fatal thing to do.Was it a trick question? She was the Instructer in charge of us didn't she know.How did I know I was a beginner for goodness sake!
I decided it was a trick question and I couldn't've been good enough or she wouldn't've asked anyway staying down for a term or two wouldn't hurt as it would improve my skills so I said "No"
So everyone else said "Yes" and got promoted and I stayed down with the new intake of beginners.....problem was she never asked us again so three years later I was still in the beginners class yet guess who got to ride all the Buckers bolters and rearers that no one else would ride because I was too scared to say I didn't want to ride them either.
Mentally I have always been a beginner and when I lost my nerve a few years later I left horses as a beginner.
I took up riding again a few years ago on Sarah-lee,my beautiful little hinny but have never had another lesson since school although I have had a couple of western "tasters"
I still don't know what level I am but think of myself as a beginner.Isn't it funny how one question can change your life? If that Instructer had just given me a bit of confidence and put me up a class I probably wouldn't've lost my nerve in the first place

by the way I am now Backing my own mule because there is no one else to do it so I'm gradually gaining confidence.
