19 lessons in, covering the full core grammar skeleton plus five practical vocabulary domains. This lesson doesn't teach anything new - it interleaves everything so far, which is exactly the kind of effortful, mixed retrieval that builds long-term retention rather than just fluency you'll lose in a week.

If you missed more than two or three, that's useful signal - not failure. Revisit the specific lesson linked in the question, not the whole set. If everything felt solid, that's the ideal state to build the next stretch of lessons on: longer dialogues, real listening practice, and eventually a full timed Modellsatz.
Full index of everything covered: Lesson Index. When you're ready, a good next real-world test is the official Goethe A1 Modellsatz - not to pass it yet, but to see exactly what the real exam format looks and sounds like.
Tell your teaching agent which topics felt shaky - it'll plan the next lessons around exactly those gaps.
