Pro tip: Duolingo is a game and basically a dead end for properly learning a language. If you want to really learn, you need to build intuition, and that only comes from huge amounts of level-appropriate input. Find yourself some good native language podcasts that are targeted at language learners and native reading material. Search for "Refold" for a better strategy (no affiliation, it's just awesome), and make sure that whatever you do, you enjoy it. Language learning is a marathon, the fun is in the journey, not just the destination.
