I watched the Andrew Ng videos in coursera - I honestly didn't care about any course work, I was just trying to watch the vids... did I do something wrong?

  Not exactly, but the coursework is worthwhile. It's well designed so that you get to only focus on the topic at hand, not setup or scaffolding of any sort. You really get a feel for how to turn an equation into vectorized code, which the video lessons can't give you. I've completed the first Ng course, the later five-course specialization, and a few other courses (Odersky's Scala course among them). Still, 4% doesn't sound unreasonable: I too have enrolled in more courses than I completed.
