Practice all skills: less than 20 questions
I got a practice session with only 10 questions today. Another session had about 15 questions. The other ones consisted of 20 questions each, as usual.
Now, I understand there can be less than 20 questions if there are not enough sentences (like when you practice a separate word), but there are surely enough of them for the "Practice all skills" option.
Could you please look into this?
I'm not sure how the amount of sentences is decided. The words are probably chosen at the start and that might influence the amount of sentences as some words occur more often than others. I've actually experienced the same thing as you and I thought it had to do with the amount of practice that I did at that time. Here is a similar discussion: http://duolingo.com/#/comment/245977
I'm sure there are many words that I don't remember well. I peek on words I have forgotten. Even if Duolingo considers all my words to be strong, some of them are stronger than other ones. Why not give me my weakest words even if they seem to be strong? If all the words are equally strong, why not give me random words and sentences?
These are mostly questions and ideas for the developers :-)
Okay, so today this happened again: my first practice session had 14 questions, the second one 10 questions and the third one 16 questions. Every round had very few words, for instance, the second round only had "Insekt" strengthened. Why could not "Insekt" be combined with the first practice session? Why give 3 short sessions instead of one or two proper ones with 20 questions?
This all is for German.
