It is essential for each chapter to start on the right note. The chapter should have its own mini introduction. This will tell the student what the chapter is about. The current chapter should also have a link to the previous chapter. There should be sub-sections inside the chapter. This will save the content from being scrambled and confusing to the reader. Once this has been done the material should proceed in a logical manner. The writer should treat each chapter like a body of work by itself. Readers like to read each chapter one at a time. That is why the formatting of each section and sub-section is an exercise by itself.
