How to unlock the rest of the words later of master the whole tree
I have been seing that different user that mastered the german tree in their profiles doesn't have the same amount of learned words. I would like to ask for the Duolingo Staff to create a way whereby i could unlock the rest of the words that were leaved behind and was not learned by me. So when someone master the three and doesn't have all words they can yet unlock the other ones. Thank you.
