Nightowl I agree with Sophia that printing Christian's scores is an option. So far, I am mostly using the scores after watching the lesson couple of times. To be honest first three lessons have repetitive bars, so the score is open just as a reminder.
I also agree that it is difficult in a different way than the method book. Even that simple LH is tricky because of swing pattern. Yes, hands separate is easy but when playing hands together, my left hand likes to rush or drag and messes up the rhythm. For example; lesson three introduces triplets that's supposed to fit together with one LH beat. There's nothing like that in my method book so far.
