You have now conquered your shiny English 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 2.72 lessons per day on average and you still have to finish 12 sessions to get all of your skills to Level 6, you would be there by 2022-06-01 if you keep practicing at your current pace.
Keep going! =)
If you ever wondered what are duolingo lexemes: these are lexeme_ids from our extended profiles and they are actually neither lexemes nor words since they include all word forms and they also include combined lexemes such as "bonne nuit" in the French course, and there are a few duplicates as well, but the total number is consistent across all users having completed the same tree version and apart from lessons and skills it's the only countable number in your profile that can tell you a little bit more about your tree progress.
