Does anyone have experience with tutoring or similar school intervention?  I don't know much about Oxford & Sylvan tutoring.  I have a bit of experience with a private tutor, but I'll say that I'm not blown away by it.  What options exist?  What works?  Anyone know of an "ON-switch" for my kid?

This was brought to mind while reading another thread and I didn't want to hijack it so I decided to start it's own thread.
