Unfortunately impossible to say solely based on being a former SSC. Some people got the credential when the standards were much lower, and may never have been coaching to the current standard. Others may be perfectly good and let it lapse for whatever reason. Still others may have at some point rejected the premises and fundamentally disagree with the SS approach and you'll be getting something completely different, in some cases possibly even hostile to this approach. The world is a weird place. Is there no one current near you?
