Skill still stuck at 75% after repeated practice

I use the extended profile ( to keep track of which skills need review. A couple times I've had a skill get "stuck", where it stays at 75% even after I practice it. Previously I've been able to get it unstuck by leveling up, but now I have a level 5 skill that is stuck. Anyone figured out a way to fix this? One of my kids is having the same problem too, but with a different skill.

Thanks for posting about it. I have the same problems for my spanish and portuguese trees. In the first case for the skill "people 3" and in the second one for "adjectives I". I see the same sentences over and over... I also realised that, for some trees, the number of words is not at its maximum even when the tree is fully golden level 5. It worked well until recently, so I hope that they can solve these problems soon.

This is a very old problem. I have an account that was originally on French Tree V2, then got upgraded to V3 then to V5 (aka tree12), that account has LOADS of skills that won't go to 100%. I have another acocunt that was originally on V4 (tree8) that got upgraded to V5 (tree12) which has a few skills that won't go to 100%. Yet another account that started with V5 has (so far) no broken skills (though I'm far from having completed the tree with that account).

The most frustrating thing about this is that the staff don't seem to care at all. At some point there'll be yet another version of the tree and ALL my accounts will likely start to have more broken skills and the only solution will be to register YET ANOTHER account and start from scratch all over again.

Hello! Not to worry its not you or your kids fault that its stuck. Its probably just a bug, you should report this bug to whoever created that website. Is that website made by Duolingo? Because if so I know where you can report it to and have it fixed, or is it another website. Please let me know so I can help you further! And hopefully then it can be fixed!

Please get back to me so I can help you out!

How many times have you practiced it? I’ve found that for skills with a lot of lessons (which usually means a lot of vocabulary) that it can take 5 or more sessions to bring it from 75% to 100%. I think this is because it takes a lot of sessions to get sufficient coverage of the vocabulary.

That's a good theory, but in this case I think my problem is probably due to a bug with DuoLingo. Every time I practice the skill (5+ times over the last couple days, plus a couple general practices), I get the same words over and over, even though I know that Travel 2 includes a lot more.

I have the same problem in the german tree. The problem is also discussed here:$comment_id=28442229

I submitted a bug report if you have not done so already you should too. The link is below:
