Registration for classes during the Summer terms is optional, so the process to do so differs from the other enrollment terms. Graduate School students will be made eligible to enroll by the Office of the University Registrar. All other students must request Summer enrollment through the Registration section of DukeHub. The Summer schedule of classes will be visible to all students without needing to bookbag or enroll. However, students will not be able to bookbag classes until they are term active. Drop/Add may be done prior to the beginning of the term or during the first three days of the term.
