Howdy Heinz!

I am probably in a similar case to you. I've been "playing" the guitar, on and off (mostly off) for years, and recently enrolled in this website. I believe that, even if I already know most of the material on the fundamental lessons, it serves the following:[br][br]- making sure I have all the skills to properly face the following lessons (spoiler alert: I did learn new stuff)[br]- giving me some confidence in my current skills

- forcing me to start a practice routine (already picked up the guitar three days in a row!)

And even through the courses, if I find the material too easy, I am trying to find ways to complexify the exercises (for example, using the full chords instead of the simplified ones on the first lessons, playing not only the melody, but also the chords of those notes on simple melody lines, soloing to the backing tracks, etc)

Have fun!
