Skill won't strengthen
Hi all. I'm having a problem where the skill "Pres. Per." will not strengthen. I completed the skill for the first time just a couple of days ago but it was already down a bar yesterday. I completed the strengthening lesson last night, but the skill did not strengthen. Frustrated, I left it for today. Today the skill was already down two bars. I completed the strengthening lesson with all three hearts and the skill strengthened by one bar. I re-did the strengthening lesson again with two hearts remaining, but the skill didn't strengthen any more. I re-did the strengthening lesson just now yet again, but the skill is still not golden. I have periodically had this problem where I have to strengthen the skill twice for it to become gold again, but I have strengthened this new skill four times in less than 24 hours, including some times at full hearts. What is going on here? Is this a glitch? Has this happened to anyone else? It seems absurd to strengthen the skill five or more times in one day for the thing to actually get golden again.
Just to be clear, you're doing the skill-specific strengthen drill (the "Strengthen Verbs: Present Perfect" button on the skill summary page) and not the "Strengthen Skills" or "Practice Weakest Words" buttons found elsewhere, right?
The strength of any given skill is actually the average skill of the words taught in that skill. In the case of the "Verbs: Present Perfect" skill, there are 66 words. Each time you do the skill-specific strengthen exercise, a maximum of 9 words from that skill will be selected for practice (more words from various other skills may be improved as well depending on how the sentences are configured on the back-end) and improved to full strength upon successful completion of the exercise (potentially less if you do a timed practice and are unable complete it). For a skill with so many words, it will take several practice sessions to boost the averages up enough to get the skill's strength rating back to gold status. Just keep at it, or as another user suggested, redo the lessons instead. Remember not to peak at words unless you absolutely have to. Doing so will increase the rate at which the strength of those words decay.
There are multiple threads about this - It appears no debugging has been done in 3 years. New features are awesome, but fix the actual product first please.
This just also happened to me with the skill "Abstract Objects 1" in the English-Danish beta course. What is wrong with duolingo? I don't forget the words of danish, because I'm a native, so it is already annoying that I have to do those skills again. Come on now it takes even more wasted time to complete the tree. So ridicolous.
I don't know, I would suggest reporting it to the Duolingo staff. Good luck!
I have a similar thing occuring on the mobile app, but not on pc or ipad. My tree is at full strength on two platforms, I just have bars missing on the one lesson on the mobile app. It's been like that for a week, I just ignore it and take it as a glitch.
V.Pres.3 just will not strengthen on mobile for me.
