Why won't my skill strengthen?
The strength bar went down on "Communication" in German, so I tried to strengthen it, but after upwards of 15+ times, it will not go back to full strength?! I also have this problem with Future 1, also in German. What the heck is going on?
When you get something right it goes up, but when you get something wrong it goes down to allow you more practice. I recommend redoing the lessons when you are having that much trouble with it. The strengthen feature is good when you think you know most of it and just want to test through it, but the timed version has 20 questions and not everyone can do them in the time allowed. So you have to do it more times if you didn't finish. It gives 20 points, while the untimed version gives 10 points for 20 questions but it can be better for people who are not finishing on time. Plus if there are many lessons in the unit, you will only have strengthened some of the lessons and not all of them. DId you get all the answers correct all 15+ times? Then I would definitely think there was something wrong. If you cannot bring it back by redoing the lessons, then it is serious. It may be that you did not get all the vocabulary that needs to be reviewed in the strengthen feature, you can also go to Words and press strength to have them ordered by strength then press strength again to have it reversed to show your weakest words first. click on each of them and click on more details to review each word.
Not almost all, all. Remember every time you get a word wrong your strength goes down. I highly recommend redoing the lessons, instead of using the strengthen skills. 15 x 1 wrong, or 2 wrong can add up to more practicing. Are you doing the timed practice? How many are you getting right? I can do 1 right and the level goes up. I can do 5 right and 2 wrong and the level goes down. 3 out of 20 is the most allowed, so 2 out of 5 is like 8 out of 20 when you look at the percentage wrong.
I hope they find out what it is, but it is confusing that it only happens for certain skill sets. Please indicate what you were using: timed version of Strengthen skills, untimed version of Strengthen skills or Redo lesson and which lesson? Did you Redo all the lessons in that skill set? When you have redone all the lessons in the skill set and had none wrong, then you should be safe.....for a while. Duolingo assumes that if you haven't reviewed something lately that you will be forgetting it and the skill sets fade. The longer it has been the worse the fade. So if all the lessons in a skill set have faded, you are better off redoing the lessons than using the Strengthen Skill.
