13.2. Winter Session Classes and Schedule Changes

If you choose to take winter session classes, please observe the dates and deadlines posted on the sites below for paying tuition, getting a refund, filing for GRO, and withdrawing from courses:

 https://registrar.arizona.edu/dates-and-deadlines 

• Contact the Summer/Winter Office for questions. 
• LATE DROPS or SCHEDULE CHANGES after the posted deadline: If you need to make a schedule change (i.e. withdrawal or other change  after UAccess is no longer available for these requests): 
  • Use the Online Change of Schedule Request through the Registrar's office: https://www.registrar.arizona.edu/cos
  • Your request will get routed to your professor as well as the College of Science for approval. The Registrar's Office will notify you if your request is approved.  

Note: Please avoid waiting until the last day of the course to request a change, as the procedure involves a few steps that take time for processing! 

• Approvals for excess units to be taken during the winter session will not be approved. Students are limited to 4 units during the winter session as per University Policy.
