I mentioned in an early entry that at least in Japanese, each 5-minute lesson now starts with (what they think is) easier exercises, gradually moving on to more difficult lines from the same category. This is now more official, it seems, or perhaps I am in a test group again. When there are just a couple questions left, if I haven’t failed so far, Duo the owl appears holding a dumbbell, saying that we’ll have some harder questions. I don’t really notice a big difference in the final lines of the exercise, but the end of the lesson was already a bit harder for weeks now.
I haven’t really moved further down the skill tree for months now, because they updated all the exercises with kanji where these are used in Japanese print, instead of leaving most of the text in hiragana as they originally did. So I have to relearn it. But that’s OK, because it will help me learn to read actual Japanese. Or at least very basic Japanese.
