What level of language proficiency?
After mastering all units of the skill tree (in German, for example), what level of language proficiency would I likely attain on the ILR proficiency scale?
I would guess Level 2 at most, before spending at least a few months in a German-speaking country to get to Level 3.
I seem to learn to read and write well before developing an ear for it. Looks like Speaking/Listening for Level 3 ("knowing" the language), being able to hold a normal speed conversation- it's about the only way to practice for it, I think.
