How do you refresh a skill?
Refreshing a skill is the same as strengthening a skill.
To strengthen/refresh a skill, you can redo a lesson, or do "Lesson practice" (home page), "Practice weakest words" (vocabulary page) or "Practice skill" (each individual skills page).
If you use the iPhone app, you can redo a lesson or select "Strengthen skills".
I´m sorry I am new on duolingo and find myself a bit confused. Where is that vocabulary page? it would be cool to practice my weakest words!
Hi! The vocabulary page was removed. I think they said they might add it back. It was cool. I hope they bring it back soon.
