Is there a level update?
It seems to me that i'm stuck on 56% although I have completed the whole course and reached level 10. Is that right?
Same here, i have completed the course and reached level 12, still at 44% though. Does it have anything to do with the fact that i did not use the microphone?
No idea. And now I see that you have completed the course and reached level 12. I have completed it and I reached level 10! There is no level 12 if your first language is Greek
If you practise more, redo lessons, etc, you get more XP. More XP leads to levelling up. Maximum level in any language course is 25.
