Once your instructor has given you an add code, you will then proceed into Registration Planner. Once in, you will follow the steps in "How do I drop/withdraw from a course in Registration Planner?" to withdraw from the course you are currently waitlisted in. Once dropped, you will then add the CRN number into the text field on the Current Schedule screen to re-enroll into the course. A popup will then appear and ask for the add code your instructor issued you. Insert the add code into the text field in the popup and confirm that you wish to proceed. You will then receive a confirmation popup showing that you had successfully enrolled into the course using the add code.
