Turnoi. Just as a PS to my last comment, I want to say this.

As we get older, many of us forget what it was like when we were young and at school.

All my teachers were qualified in their field of expertise and had all attended teacher-training-school. Yet why do I remember 'good' teachers and 'bad' teachers?

Having a degree does not automatically make a person a good teacher. Not having a degree doesn't necessarily make someone a 'bad' teacher.

Attitude, ability, honesty, integrity, and making students feel comfortable, are qualities that in my opinion, are far more important and relevant than a genuine degree in ballroom dancing.
