Every course includes a schedule. It lists the time recommended for each assignment. Typically, it takes between 30-60 minutes to complete an assignment depending on the grade level. Based on this time frame, a typical course takes between 360-600 minutes to complete. This is about 6-8 weeks if your students have computer class twice a week. However, if your students have computer class every day, a course can be completed in about 2-3 weeks.
