Hi, i keep practicing a skill over and over again and sometime with no mistakes yet it is not getting strengthened? why?
I agree with Lrtward. The reason that works is because strength (based on my observations) is based on the average strength of all of your words. If you click on your "Words" tab, you'll be able to see which specific words have decayed (click on "Strength" to organize them properly) and pick the lessons that contain those words.
I'm having the same problem as above except specific words will not strengthen, no matter how many times I practice them in Android, PC, lessons, strengthening, timed practice, untimed practice...nothing works
I have seen people say that when that happens, to re-do each lesson inside the skill rather than strengthen the entire skill. It's not a fix, but it's a reasonable workaround, at least.
i have the same issue and I've tried to strengthen each lesson inside the skill itself and yet nothing is happening !
I'm seeing the same problem. I strengthened the same skill twice in a row. It has 6 or 7 lessons in it, and both strengthening sessions different words were tested. I only went up 2 bars though. On the second strengthening it didn't go up at all. I only got 1 wrong. Looking through the forums it looks like this was a problem even 2 years ago. :(
I find that if you come out of Duolingo and then go back in it has registered that you have done the skill.
