I've reduced my score from 5 to 1 because I'm constantly being marked wrong when what I've inputted accords with duolingo's correct answer. I've complained numerous times and no one does anything. I'm going to uninstall and then reinstall the app to see if this fixes it. But I guess I'll lose my 1040 day streak and motivation due to this. My contract is over soon so I'll try Babbel.
