Hi @Ron49 , welcome to TAC. The idea here isn’t about mastery of the material, It’s about learning and understanding the material as presented (which you have done) as well as developing a consistent guitar playing routine, and having fun doing it. Over time, you will see progress – everyone here has for sure, without a doubt.
I think it’s great that you purchased FW, and you can start it any time you feel. For me, I felt I needed to “bone-up” on some of the technique courses before doing FW (YMMV). To be honest, I felt a little intimidated at first, because I thought I didn’t know enough of the basic music concepts to attempt FW, so I put it off for a little while. (I later found out I was wrong about that). Then I came across a Skills Course titled “Foundations of Fretboard Navigation” – well, after completing that, the thirst for more fretboard knowledge pushed me to start FW. I really gained a lot from FW although it didn’t all sink in immediately. So that was my journey leading up to FW. But this is your journey Ron, I do recommend doing Foundations of Fretboard Navigation before starting FW, but it’s your journey, and you can take the path that you want. Just remember to have fun👍
