The Latin course accidentally gave me the "Champion - You conquered a course" achievement
I just started the course and I'm not even close to finishing it. I don't know why I got the achievement, but it annoys me and I don't want to see it. How can I get rid of it again?
It did not bother me, since I knew I would soon finish the German and Polish trees. Maybe you should report it as a bug:
To track your progress, don't forget your duome pages (the exclamation point next to "Lessons" tells you how many lessons you have to complete to finish your tree):
Another thing that really helps me with Italian is Toran's Duolingo Strength extension:
Thanks, I'm aware and Duome and I use it often. Unfortunately it cannot give me back that seamless in-app experience that I had using the achievement overview. Anyway, I can imagine worse problems...
I will give that Strength extension thing a try. I know it used to be an official feature once, but it was before I have started Duolingo.
