Hi there - thanks for the interest in the program and your great questions!
I recommend focusing on the aspects of your playing that you find challenging, or that you are trying to improve. You can play whatever you wish to illustrate where you're at. We've had students play through an entire song, or play through chord changes, or even improvise with a backing track. You can video yourself any way you like, just make sure us instructors can see a full view of the guitar and your hands!
Give it a try, and we look forward to giving some constructive feedback!
Mike
Keep rockin!
