Within that are a series of Core skills which I am sure you have many of. Outside of the core at every level are other examples if you want to expand more at a level. No electric guitars on that page and a LOT of tutorials. There are I think ten Core skills to go through I have played through 4 or so far.
The idea - and it works for me - is you play through the things you know and skim and complete them - to find the level where you start to learn
I'll give you an example of a course I find hard - on this particular thing he happens to be playing an electric guitar but it works on acoustic. It is classed as intermediate and I class myself as being a competent guitarist. Ande I have some off so far but I have a found a level competence where I can learn. I learned loads - this is single note stuff in quite a lot of styles but applicable to many. 30 licks for country, jazz, bluegrass, blues etc. It is more there as an example of the teaching method and quality of explanation etc
I have no interest in this other than I thought I might be useful to people as most people I have asked have never heard of it
Not as a plug but I have a Youtube channel with various stuff on which shows you the level I'm at. Many are better of course - it's not to go you play well. Neither is to start a discussion whether I'm good bad or indifferent. Youtube for Nick Some of them are playing live with friends. Some are just practice or sharing odds and sods of thoughts with friends. None of the solo acoustic guitar is of performance standard.
