Students who are aged 60 or above get free tuition for credit classes when taken for an audit grading option. Auditing is taking a class without receiving a grade or credit. This tuition waiver is available on a space available basis and does not cover any fees. Many classes fill up early, so space is not guaranteed. The only way to secure a spot in a class is to register early and pay full tuition. Auditing students must be registered for eight credits or less per term. Not all courses are eligible for the audit grading option.
