For non begginers, what level did you get at the test?
Level 6 here. Not bad for a start. I haven't forgotten all my Esperanto...
Level 8. I might have done a little better, but I actually ran into a couple of translation issues (for example, in one sentence "malsano" had to be translated as "illness" and in another "sickness." I used "sickness" for the first and "illness" for the second, and got both wrong).
Edit: I suppose I shouldn't complain. Now that I've read the thread, it looks like I'm the one on this thread who tested highest.
I speak Esperanto and English everyday, Esperanto for 3 years or more and English for a bit less than 1 year. I tested out 8 skills, I often had problems with articles (I always forget to put "a", probably because I'm Russian). I also didn't know some words like "lamb" in English. And I must admit that I wrote "vivas" instead of "loĝas". Normally I do not do this mistake if I just speak Esperanto but it seems that translating from English to Esperanto is a bit different thing. Somehow seeing English sentence influence on my Esperanto thinking and vice versa, I think duolingo is also a good training for switching between languages. I normally don't do it and it is a little bit difficult to set the brain to do translation work. Well, I'm going to complete the tree anyway and help to find missing translations.
