The NUS Business School operates on a modular system.  Students have the flexibility to design their curricula and to pace their studies.  They also have the freedom to take all modules in the sequence they prefer, subject to any prerequisite requirements and to modules availability through the Centralized Online Registration System (CORS); i.e., there is no fixed course of study. Students considering a double degree programme may be further guided by its more restrictive requirements.  New students choose their modules during the Orientation Week.
