Mi finis mian Esperanton Arbon!
YES! I was really working hard these past few days and it feels so good to finish! Any tips and suggestions to further develop my Esperanto (;
Yes, I had that feeling too. As said above, repeat the tree keeping it golden. I'm doing it right now. Also, you can watch Evildea videos in YouTube, read the Esperanto mega post for more ideas: https://www.duolingo.com/comment/9139466
...and learn Spanish preparing yourself for the Es->Eo course ;-)
