No one is looking for a Pro. MM makes a great point.Yikes. I am no pro rider
The trick is being able to filter out all that knowledge you have, and pare things down to basics that anyone can pick up on. The next essential is being able to read your students; Some need to be taken aside and given more elaborate instruction, maybe away from other people zooming around which is making them nervous or doubt themselves. Others need to be told to stop over thinking it and just get out and ride.
If i had $5 for every student who told me 'i can't do this' but in the end passed, more often then not with a perfect score, i could start planning a retirement.
