My question is about the Minor Pentatonic scale, more specifically the A Minor Pentatonic scale.  When I learned it (granted, not as fast, or as smooth as Anders,) I thought that was it, that I had learned the Pentatonic Scale.  Then I started to read more, from different sources and they were talking about the A Minor Pentaonic Scale in positions 1-5. 

So my question is, how many Minor Pentatonic scales and/or positions are there and why do the lessons only show the Pentatonic scale in A Minor, or did I miss something???  I'm finishing up Fundamentals 1.
