Not getting credit for practice?

[bigbl5]

I recently had one of my skills degrade (accusative pronouns). Ok, fine. I practiced that skill at least 5 times and have multiple "practice all skills" yet it does not return to "mastered." Am I doing something wrong or is it a bug?

I wrote about a similar post about it: http://duolingo.com/#/comment/337345. The shortest way to "master" your skill back is to redo the lessons that have decayed. Practice does not always help. I think it is a bug.

Ok, thanks!

If I remember correctly, it is not a bug, however you just didn't practice any of the "degrade"+d skills, so it didn't go up.
Try practicing your "weakest words" under Vocabulary.

I did try this as well and it didn't even give me any words from that section.

I tried redoing the lessons and got credit. However, the unique thing was that I was actually given several new words when I did the lessons again. I wonder if that is why I wasn't getting credit when i was just practicing...Oh well, I never turn down new words!
