I've been working on this part of the for about three weeks now is that normal? what else should i be working on?
You can't ever know the pentatonic minor scale too well. Just learn more than the normal box, and move it around on the neck.
I view the pentatonic scales as single notes, meanin I never use the box pattern. I memorize the individual notes and know the scale well nough to do anythin with it.
