I started my 7 day trial period a few days ago. I got through where the three paths split and went down the classical path for a bit. Now I wanted to check out the pop path. The first video says I already learned the A minor chord, when did that happen!? It put me in a song and there were notes on the staff I haven't seen before. Am I missing something or am I just suppose to learn those on my own and know how to do them at this point? If so, why am I paying an app to teach me?
