There seem to be a lot of people in the exact same "boat" on here, including me! I knew a bunch of chords and some songs, but had to "unlearn" some bad habits during the Fundamentals 1 course (e.g. building chords upside down instead of placing the bass note first). From a fellow newbie, don't resist unlearning and doing it Lisa McC's way, it will only slow you down and impede your progress. If you re-learn it the right way, it might take a couple of hours of your time, but you will open up the road to progress at a mind-blowing pace. Then again, maybe you have no bad habits?...

I can tell you that I have been doing this now since early February (joined last day of 2018 and didn't really start using it during January) and I am half-way through the Fundamentals 2 course (there are a couple of other guys on here that have been moving even faster, go at your own pace). It is unbelievably effective if you stay with the lessons, use the practice sessions, jam tracks, loop (on the videos) and learn a few songs from the library along the way. Lisa McC really has a winning formula and everything builds off of what came before. Caren and others also really build on what you've learned in Fundamentals when you watch the song lessons.

And we are only beginning to scratch the surface . . . .!
