Duolingo's free Swedish course is great for beginners and intermediate learners. It teaches you Swedish from step one and plays like a video game - including the addictive part! The learning system is visually stunning with cartoonish graphics and photos to illustrate vocabulary and concepts and help you memorize them.
Most importanly, perhaps, is that it is quite fun and keeps you coming back for more learning. Thus, there is no lack of motivation to learn a language.
