That is a pretty easy one. It is not so much about your skills as in how good you are, but your safety and gunhandling. At the advanced level a student needs to be at the point where good, robust, safe gunhandling is automatic. Anything less and not only is it dangerous, but slows the class down. Of course you should also have the basics down before attending an advanced class, but some people dont get that. Hope that is a little help.
