Anki is a great tool to start with. Active recall testing and spaced repetition make Anki more efficient than traditional study methods. Anki's repository of shared decks makes Anki that much more valuable by allowing me to browse decks that others have created and download those that I wish to study.
To find shared decks (including our AboutProjectManagement.com decks - subject of a later post) select download in Anki and search by the desired deck's name/subject.
As you can see, I just uploaded AboutProjectManagement.com's deck - only 14 facts so far. More about this in part 4 of our continuing series.
