Deutsch Akademie offers a free online grammar course, offering more than 20,000 exercises for all levels, from A1 to C2. If you’re an independent learner, this website is for you. From the audio course to our beloved grammar, there is even a help function where online students can ask a German teacher for help when they have questions, throughout the textbook lessons.
If you prefer a dash of humor with a visual style of learning, check out the cartoon Bavarian characters on the German Flashcards website, while other German websites, like DeutschEd, offers online German lessons (including pronunciation) at Deutsched.com. If you’re in the mood for bookmarking websites for later learning, don’t forget the popular German Articles Tool and this vocabulary building website with structured exercises.
Something else I found was the Deutsch Akademie Conversation Club. If you prefer the face-to-face style of learning, you can join a group at your level by signing up at the office.
