Welcome. If you're interested, there are free Classical lessons here. You can get feedback on your progress from other players. If you take all the courses, it's the equivalent of 6yrs of music school. If you take the optional final exams, apparently it has official status in France, and would count towards your entrance requirements if you were to apply to study music there. The forum for the classes is: viewforum.php?f=41

The classes here don't seem to teach basic music reading, or some basic info about beginner Classical guitar use. You may want to supplement the lessons here with extra reading/explanatory/pictorial material. I like the very popular "Solo Guitar Playing" book/CD series by Frederick Noad (includes teaching how to read music, and detailed explanation of technique). Noad gets you quickly into playing some musically pleasing practice pieces. You may also want additional explanatory/instructional videos. I like the free ones at https://www.thisisclassicalguitar.com/lessons/
(includes teaching how to read music, and detailed demonstration of technique). The Noad is my favorite of the 4 beginner approaches I've examined, but they all offer something unique and valuable. I use Noad and the classes here, supplemented with articles/videos from thisisclassicalguitar.
