I've finished the French tree!
Started with no prior knowledge of the language, I've been using Duolingo since 5/2014 and today, I am happy to share with all other French learners: I completed the French tree on 12/7/2015 :)
I've just taken the progress quiz and this is my result: 4.28/5.0 after one year of effort! :D (should have taken it on La Fête nationale :P)
Along with using Duo, I also listen to podcasts and watch French-speaking movies (for kids, lol). I still have much to learn, though.
Thank you all - Duolingo learners for a friendly and supportive language-learning community; the French team, especially Sitesurf (you've helped me tremendously), and thank you Luis and the team, wholeheartedly!
Felicitations! I also finished my tree few days ago and I understand your joy!
Felicitations. Je souhaite toutes les bonnes chances au future! It's my dream to complete the tree!
Congratulations! I'm in the same boat as you--I have no prior knowledge of French, but it's my goal to complete the French tree. The huge improvement in your scores in a year is inspiring!
