I have completed the Danish "Clothing" lesson four consecutive times, but the software still says that that skill is weak. However, the past four times, I have completed the lessons and only missed one or two questions. The last time, I did not miss any questions, but still it did not say that I had strengthened that skill set. I am wondering if this is a glitch in the software, or if Duolingo thinks I'm that stupid when it comes to Danish clothing. :/
