That may have to do with Duolingo optimizing for paying and returning customers instead of for fluency.

Their app has to be "fun" or in flow rather than in that difficult challenging place to actually help you grow.

In learning both German and Old Norse the most helpful thing for me was to translate texts, read them aloud to a fluent speaker and get feedback. Which is hard to scale.

Do you have any more detail to your approach? Do you use graded readers, or do you find that a dictionary and basic grasp on grammar is enough to struggle through pretty much anything?

... Do Old Norse graded readers exist?
