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 German golden owl.
Give it a try! =)
