Students taking an online science class should expect to log in and complete lessons and associated assignments daily. Courses can be accessed 24/7, which allows students to work ahead. Students have access to a course schedule with due dates at the beginning of the term. Late work is not accepted unless the student has a documented emergency or an excused absence. On average, students should expect to spend 60-90 minutes per day during a semester, 120-150 minutes per day while taking a block course during a semester, and 240 minutes per day during a summer semester.
