Assuming you didn't race through anything, I think your time would be better spent going through Ander's GF2.
Don't get me wrong, Lisa's GF1 is a good course but going through that after completing Ander's GF1 will be like taking a step backwards, especially if you go back to one-finger chords etc.
I wish this forum had a "block user" feature. Possibly I'm not the only one......
