Having a well-considered syllabus is of course crucial to a successful course. But sometimes it is necessary to adjust the syllabus to fit the particular class. Some students may need more time and instruction before moving on to another part of the syllabus. Some readings, for example, may be more suitable for different classes. Sometimes going more slowly can help students better understand material. So flexibility and adaptability are crucial to having a successful course. The syllabus is a road map, but sometimes their may be more suitable paths.
