Students are able to change their major through their myUCF.
Some majors may require the assistance of an academic success coach in your college. A change of major request must be submitted no later than three business days in advance of classes starting for the fee waivers effective to be applied in that given term or term sub-session. For requests submitted after this deadline, the fee waivers will be effective starting the next term.
