Refresher?

If you had an opportunity to take a "Refresher Class" for your concealed handgun permit, what would you expect to see?

The guy who I took my CHP training from is asking if there is any interest in something like this.

It is hard for me to think of any real reason to take a class like that in particular rather than something more advanced. I suppose there could be a section on updated gun laws, or something like that, but I kinda feel like this is just an opportunity for a quick buck. A guy's gotta eat, though, I suppose.
