Course prerequisites
A prerequisite indicates the specific academic background or general academic maturity considered necessary to take the course. Permission of the instructor is understood to be an alternate to the stated prerequisites in all courses. An instructor has the prerogative to direct a student who lacks a stated prerequisite to drop the course.

It is university policy that the instructor shall inform the students at the beginning of each course if students who have not met the prerequisite requirements must drop the course. Course prerequisites are listed with each course. If you need the description of a course listed as a prerequisite, use the ISU course information Web site.

Auditing
Auditing a course is enrolling in the course without receiving credit. Tuition is charged as if you were taking the course for credit. The course instructor must approve the audit.

You must register to audit the course by the 10th day of the semester. Audited courses do not count in determining full-time or part-time student status, and do not apply toward Veterans Administration benefits. Audits are not recorded on your permanent record except by special request.

Videotaping/audiotaping classes
Courses may be videotaped for various reasons, including distance learning. Instructors may audiotape courses for personal reasons. Audiotapes may be made to accommodate a student’s disability. You may not record and/or reproduce audiotapes of classes without the instructor’s permission.
If you miss an ICN session which originated on campus and want a videotape, you must obtain permission from the instructor and pay for the tape, duplication costs, handling and shipping. The master tapes are erased approximately two weeks after the session.
