I had this question too… but also if I skipped a day, how come I can not go back and watch that lesson? Don’t the lessons in one week build up to a song? How will I be able to play that song now? Kind of bummed. I also thought I could go back to lessons in at least this week, but it doesn’t look like I can do that either. This messes with my perfection ideals…. makes me want to quit for the week and start over next week. Ugh.
