Study notes for understanding the course and revising its essential ideas. Each topic begins with core knowledge, develops the explanation and ends with evaluation guidance and a compact recap.

First learning: start with Must know and definitions. Follow each explanation from cause to consequence, then use the diagram and Develop the judgement to test the conditions behind the result.
