I've found that mind mapping is the important tool when you need to know and understand the material. I mind mapped the course outline and only photoread the course material. I found in doing so I had a sound understanding of the material. It made sense if I had difficulty mind mapping any particular areas then those are the ones that I would have superread and dipped.
A point to remember. With superreading and dipping you are making an effort not to get bogged down on the material you know and move on to what you do need to know.
