Students who received an Incomplete in a class that used Blackboard Learn and that class is now using Canvas will complete their requirements in Canvas. The student should not enroll in the class again. Instead, the instructor should email email@example.com to request a student get access to the Canvas site to finish the Incomplete. The email must include the course number, section, and semester of the class in addition to the student's name, PawPrint ID and student number.
