You have now conquered your shiny German golden owl. Yay!Now it's time to advance to the next tree level and probably discover more content and harder lessons with each level.
You are currently making 0.22 lessons per day on average and you still have to finish 0 sessions to get all of your skills to Level 7, you would be there by 2023-01-31 if you keep practicing at your current pace.
Keep going! =)
