Did you ever wonder how soon you will get your golden owl if you keep learning at your current pace?
It looks like all of your recent lessons were timed practice / less than 10 xp per lesson, these lessons don't take you any closer to your golden owl, but if you do some regular lessons and check back here in a little while, you would see how many more days you need to get your Spanish golden owl.
Give it a try! =)
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.
