My Self Assigned Training Ground

I have been wanting to join your certification training but I am unable to afford it.
I asked myself how can I create for myself within the budget that I have some training ground to practice coaching with all that I learned here in SCS, so I started this practice of allocating 30 minutes each day and visiting Ask Brooke as well as Diamond Ask Brooke. I read only the questions that are posted there and I pretend to be the coach answering them and I type the answers to myself.
Then, I go and read what you and your coaches actually answered. At times I am impressed with my answer and at times I was way off.
I guess that goes to show how different the material is at SCS from the certification itself for those who want to be coaches. Do you think this is a waste of my time?
