A service member enrolled in an institution of higher learning who is unable, because of his or her military service, to attend classes on a particular day or days has the right to be excused and to reschedule a course examination administered on such day or days. The faculty and administrative officials shall make available to the service member an equivalent opportunity to make up any examination he or she has missed because of his or her military service.
The rights set forth in this Section are in addition to any rights afforded to persons in military service with the State of Illinois or in federal active duty service pursuant to the orders of the President of the United States or the Governor under the policies of an Illinois public university, college, or community college.
