So far, so good! I've just started with the basic lessons as a kind of review of what I already know, and yet I've already learned some interesting things. What I would slightly tweak is the fact that sometimes it takes quite a bit to match the lesson to the related materials, for example the backing tracks. In my opinion, instead of having the materials in some kind of pool, it would be much more practical to have them "glued" to the lesson :-), so you have the tools to practice right there, without having to look for them elsewhere, or far down the page. Warm regards!! Ricardo
