Congrats! I'm actually quite surprised because you must be the first person that learned a language using Duolingo. Most people I spoke with said they only learned how to answer Duo questions, not the language itself.
On the other hand, I once had trouble repeatedly failing a German lesson so I gave the phone to my German girlfriend. She failed the lesson too, probably because she was answering as a German and not as a Duolingo user.
I definitely don’t consider it passive consumption.
