I’ve tried Quick Korean (바른 한국어) just now. It was easy to register and I passed the test for Level 1. I didn’t watch the entire videos for Level 1 because they were too easy, I just clicked Go to change the status of each lesson to Registered so I could take the test for Level 1. I will try the next level tomorrow.
The video lessons are great, about 30 to 60 minutes long, and you can download PDF and MP3 files for each lesson. You can choose to watch the videos in English, Japanese or Chinese. At the end of each level (1 to 4 available), you can take a test and get a certificate if you pass. All this for free. Can you believe it?

I’ve just realized that Quick Korean has its own Forum. We can ask our questions there: http://korean.cuk.edu/community/freeView.do
