But, I do have a question.  Have you, or should I pick a path?  For example, focus on acoustic and do level 1/level 2?  Or do all the level 1s and then move to level 2?  Seems like there is some overlap across the styles.  So curious if it was designed with a particular path in mind.

Someone from GT would have to speak to this, but I don't think they laid them out as stepping stones expecting a student would complete them all. I think they were trying to offer students material in a genre that interested them. Personally I only did Blues 1 and 2 and Blues is where I spend most of my time. And not just practicing and playing, but also listening and researching. Its fascinating to me. Country is great... but I'll get what I need for any song I want to learn from a song tutorial and leave it at that. I'm not spending any time in Country. So for me, yes, I focus on a path, but maybe you want to be more rounded and work several genres at the same time. That's not for me though. I started at 56 and am now 60 and aging quicker than I would like to admit. So I need to spend my time carefully.

Good luck with what you decide. Hopefully you can find something you really want to sink your teeth into!
