I cannot master or translate?
I have started duolingo with a friend, but we have noticed a big difference between our apps: I can't master a course, I can only finish it. Neither can I translate a text from the web, which I have seen a lot of people talk about on this site. Does anyone know what might cause this difference??
You've mastered 5 lessons as shown on your page. To master them, you usually have to do some translating. How did you master them?
I have just completed the given number of courses. I have not done any translating, and when I try to click the button 'Real World Practice' on the computer version of DuoLingo, it says there are no documents available...
