Minn. Stat. § 45.34: FEES.

Fees for approved courses and related materials must be clearly identified to students. In the event that a course is canceled for any reason, all fees must be returned within 15 days from the date of cancellation. In the event that a course is postponed for any reason, students must be given the choice of attending the course at a later date or of having their fees refunded in full. If a student is unable to attend a course or cancels the registration in a course, education provider policies regarding refunds will govern.
