The german course seems to check wether you have understood the concept of these word concerning the distance they suggest. Sono/Sore near the speaker, Kono/Kore near the listener, and ano/are far away. BUT: there is no explanation when to use kono and when kore am I right? I always fail tests when they ask me about “das; jenes” for expample, which might be kore but also kono…
I don’t use this course, but if your still wondering, IIRC, sono/kono/ano directly proceed a noun.
