It is divided into three parts with a break between each four sections. Tests and quizzes for self-assessment are provided during those breaks. Of course, students have different backgrounds and levels of experience, particularly with the technology involved in the course, so the amount of time needed to tackle the early sections may vary somewhat. Some of the shorter sections are covered in two weeks. The scientific content of the first two sections will be reasonably familiar to a number of the students.
Some sections are short so that slower students can catch up.
