Topic map

Six areas, each a column. Arrows run from a prerequisite topic to the topic that builds on it. A topic takes the color of the lessons that cover it. Topics without a lesson yet are dashed. Click a topic for its definition, concepts, and lessons. For what you can do after each course, see the competency map.
