I just completed the Navajo course and got my first golden owl here on Duolingo! My tree is fully golden too! It was fun to learn this language.
There was not a lot on there. Quite a bit of repetition. But fun nonetheless. I hope that others will try it out. Perhaps they will add audio if enough people like the course. I would love to see more added to it. It was a bit difficult without audio to know how to say all of the words. I tried my best but I'm 99% sure I didn't say any of the words right.
I definitely recommend checking it out! It went by fairly quickly. I have a lot of free time though and I spend quite a bit of time on here. Anyone else taking the course? If so what do you think? Has anyone finished it yet?
It still shows that I'm only on level 10, so I will keep practicing to get all the way up to level 25 eventually.
I finished the course in May, now I have started to practise again because I found that my knowledge quickly and easily disappeared. The language is difficult and without the possibility to speak, learning is much less effective. So I can only repeat the prayer of every Navajo course participant: Please, please, add the audio at last!
