The lessons have different skill levels, although most of our material is in the upper intermediate to advanced field, with the majority of lessons focusing on fingerstyle guitar playing.
At the moment, there are no specific suggested order when it comes to the lessons, but the free course "Fingerstyle Guitar Basics" is a good start if you want to learn more about fingerstyle guitar and how to get the thumb more independent from your fingers. There are short promos for almost all lessons, so be sure to watch some of those first to see if there are any specific lessons that interests you. As a premium member, you get access to all the material on the site! A good thing might be to start with some free lessons, and if you like them - continue and subscribe for a month to see if you like the content. You can always cancel the subscription before the next billing period.
Hope this helps, and let me know if you have any other questions! I'm here always, happy to help! :)
