There are 14 modules in Exploring Creation with High School Astronomy. Each module is, on average, 25 pages long. As there are no labs or exams, students are expected to read the text and self-check the On Your Own questions to comprehend the materials. A student could easily finish the course in a semester, reading one module per week; this would be a 14-week course plan. However, it is also acceptable that a student would plan to read through a module every two weeks at their leisure; this would make a 28-week course.
