I have taken a few different cert courses, some cover more than others and some DO have their own principals, with their own policies and procedures. one each test I took there were specific test questions that pertained to informantion in their books... ie: ACE requires you renew your cretification every_____ years. Again, questions specific to the sgency and it's policies, that type of stuff. not exercise physiology questions. If you google Scirion, you will find what I found, try it cause I could not find anything specifically great on it, not even really good. I'm not knocking it, I'm just not familliar with them, maybe because they have only been around since 1997, and are gaining popularity now?
