If you would like to switch your Literature Humanities class or your Frontiers of Science discussion section due to a scheduling conflict, you can attempt to switch into a section with an opening using the change section function in Vergil during your first registration appointment or any subsequent registration appointment.
If you are unable to switch sections on your own, you may submit a change request petition to the Core office at the start of the semester. More information about Core registration policies and petitions is available here.
