IU charges the Combined Mandatory fee based on your total enrolled hours, whether you're taking classes for credit or auditing them. As your enrolled hours increase, so does the Combined Mandatory fee. If you've been charged more than once for the Combined Mandatory fee, it’s likely because you added enough hours after your initial registration to bump you to a higher fee rate.
The Combined Mandatory fee provides revenue to support services, programs, facilities, and materials that cannot be fully supported through tuition or state appropriation funding. These tools help you to succeed as a student and contribute to a comprehensive learning environment.
