Where are the progress quizes? I used to do them often and now I see that they disappeared. It helped me to see how good I am at a language and to see what I should practice more.
Here is the latest information on the new website including information for the Progress Quiz: https://support.duolingo.com/hc/en-us/articles/115002969903
Not that the quiz caused some kind of problem? They are replacing useful with popular items.
