One of the BEST aspects I’ve experienced is the mixed level option approach offered by YAF/POLY. The strategy of: “start with ___; if you’d like a little more, try this___; if you’d like a little more of challenge, add this___”
Challenge yourself, but don’t strain yourself.
You can “CHANGE YOUR MIND”.
Through personal experience, I’ve observed students of many levels can experience the same stress relieving benefits and feel fully supported by the other students in the class.
