It was excellent course. Most of the modules were available in audio, video, text & picture formats, which allowed me to switch around based on where I was or what I was doing at the time. I was able to read and review at times, just listen to it or watch the movies as I was cooking etc. Lessons within modules were very short, which allows me to start, stop, and resume studying whenever I want. Only one improvement I would have liked to have is to be able to see the answers and what I got right and wrong during quizzes. Otherwise, it was a very nice learning experience.
