Prefer course syllabus page with all topics and links
Instead of having to commit to a whole course, like at academic course, I prefer to jump in and out of different courses to learn the topics I need at the moment. For example, this format is very useful: http://cs229.stanford.edu/ . It makes it easy to understand the outline of topics, and jump into the area you want to learn. And code examples help since I can just copy them.
