Rocket Languages is the most motivating online learning program I have ever used. I have been learning Korean for almost 2 years and there are times when I skip a few days of practice simply because I lose interest. Repetition does that to you. The points and badge system encourage you to work every day and compete with the other Rocket users. It gives you the strength to go each day and have even more fun learning the language.

I've already recommended it to a few Korean language students I know. Hopefully they surrender and check it out.
