    (2) The class described in subsection (1) shall be elective and not a requirement for graduation.

    (3) A pupil shall not be enrolled in a class in which the subjects of family planning or reproductive health are discussed unless the pupil's parent or guardian is notified in advance of the course and the content of the course, is given a prior opportunity to review the materials to be used in the course and is notified in advance of his or her right to have the pupil excused from the class.
