@Hhbt I’m at exactly the same point as you - module 5. I can nail the C chord nearly every time in chord perfect practice, but when I come to play songs I often miss it and it sounds a bit dull.
I’ll be moving on when I have other parts of the module up to speed and the C chord sounds a bit better during song play.
Everything else has gotten better as I’ve moved along so I’m assuming C will too.
