In addition to registering for classes each semester, it is required to register for the appropriate RU or ER. Register for any Residence Unit just like you register for a class. Find the call# of the particular Residence Unit.
To find the call number for the kind of Residence Unit you want, look in the Columbia Course Directory
type “Richard Slusarczyk” – (Assc. Dean-Academic Affairs, GSAS) as the “instructor” for GSAS residence units. Choose the correct semester from the drop-down menu. Then choose the particular RU:
- RU: 20 points maximum (provides full-time status)
- ER: 20 points maximum (provides full-time status) ER is taken after completing 2 RUs in GSAS.
- HR ( ½ RU) allows up to three courses (part-time students only)
- QR (¼ RU) allows up to two courses (part-time students only)
GSAS RULE: After completing a total of two RUs, all students who wish to continue taking classes must register for ER in subsequent semesters. One can register for ER for more than one semester (e.g., Summer Term and Fall Term).
