Suggestion: mark skills as "learned forever"?
Sorry if this has been suggested, I couldn't find anything.
It would be really cool if I could mark a skill as learned forever so that it never depletes. I find it mind numbing to do basic exercises for a language I'm intermediate at, but basic skills deplete all the same and my OCD nags at me to get it to gold. When I have to be away for a week or longer, it takes me an hour or more to strengthen all my skills before I can get started learning again, which turns me off coming back to Duolingo at all.
I totally understand if this goes against Duolingo's philosophy, but just a suggestion.
It does indeed go against Duolingo's way of working - not a philosophy as such, but a method of teaching that's based on a spaced repetition approach.
The good news is that you can finish a lesson really quickly if it contains material you know really well, and after you've strengthened the skills a few times, they'll start decaying more slowly.
On Memrise your feature is called "IGNORE words/phrases/sentences".
On www.languagecourse.net vocabulary trainer VT your feature has an extra quiz button which is called something like "Yes, I know. Do not ask me this again - put it into long-term memory":
VT will simply move the asked word into the last Leitner index card box 6 (or was it 7? well...).
VT test quizes only ask about (new) unlearned or recently viewed words or words from Leitner card boxes 1-5 (something like that) to pickup the spaced repetition intervals.
Personally I am even looking for a way to temporarily un-learn a hard word and flag it as "re-learn this manually later" (by adding multiple context sentences manually) or by moving the word into a special "re-learn words manually later course"...
I am not aware of available software which adds all variations in a more customizable form :-(
The end user is NOT a stupid learner but the software should assist the learner in it's best / all possible ways to further customize his personal style and actual needs!!
That's nice and all, but it's getting to the point where I don't have time to strengthen all skills from the beginning, certainly not enough time in one day. And that's coming from someone who does 300XP+ days. In only ONE language. I can't imagine what it's like for the folks who have several languages to keep up with. Being reminded of how to say "hello" "i am a man", etc is no longer useful past a certain point.
