With regard to Chethams Summer School, has anyone who like myself is not up to the standard required
to enter, been purely as an observer?
I have discussed this with my teacher and she thinks it would be a good idea to go.

I was there last year, taking part in the course, but some people were observing. Someone I knew went as an observer & had a great time, watching many lessons & attending all the concerts. It certainly is a very worthwhile experience & it's cheaper as an observer.
