I remember this discussion on HN. And I liked the idea. In prep school, I used to go through my whole Math binder for each bi-monthly test even though the tests were only on the last few chapters. It definitely helped me a lot. After reading about the link you re-posted, I looked at some of the software that were replicating SuperMemo's method. (I can't remember the names right now) The issue I had was to find the material for what I was studying. Of course, the best way is probably to create your own material but that requires an extra time investment.
