I second JeffS65's suggestion. Just another subscriber here too, so no self-interest barrow to push.

A GT annual sub is very affordable tuition by any standard, and quality tuition invaluable to anyone wanting to [u]learn to play[/u], or [u]develop their playing[/u] further IMV.

Why? Structure, foundation, continuity, motivation, community, and importantly, audio-visual tution with support and interaction through the forum as necessary. Additionally or alternatively, live personal tuition is available for an additional fee.

But, to assess yourself I'd recommend you initially start at Fundamentals One. Why? The objective being to self-assess, refresh, fill in any missing gaps, and correct potential self-taught errors/technique. If you know its material and your competencies are way beyond it, you'll figuratively fly through it in no time prepared to take up new challenges at your current level of competency.

Cheers!
