Certificate test uses vocab that hasnt been learned yet.
I took my first certificate test today. I had no idea what to expect. The questions are almost identical to the "normal" Duolingo units. One major issue: one cannot see what the correct answers are at the end! This is a missed learning opportunity. I want to know what I got wrong. It would help me concentrate my study in those areas.
Oops - I did not see that you were from the admin, then I would not, with all respect, have given you a lingot. I find your answer not satisfying because it tells us what we already know. The certificate tests ought to be based on vocabulary already learned. Isn't that possible? But still - duolingo is the best free language learning program I have seen.
