The Words Section of DuoLingo = aimed at the Devs at Duolingo
I am learning Arabic on Duolingo and I often check out the words section. When I do, I find that I struggle to remember some of the words that need to be reviewed. Would it not be possible to add a link to some of the previous exercises so that it is only a simple matter of clicking on the link and doing a couple of exercises to refresh the words?
I would suggest using the word section to enhance your understanding of not only the words but how they are used in a sentence. Practice writing the sentences provided multiple times and then speak the sentence using the audio provided. Make a list of the words you have mastered, increasing the list only when comfortable with the words you have learned.
