I started in the CS373, and having a not so good experience in programming, I found the course very difficult. I mean, the style of teaching is very good. When you program step by step, you learn more and feel more confident. I think the difference between Coursera and Udacity, is the first one is more focused in lectures and homeworks, and the latter is more focused in practice all the time.
