Daily Random Assignment
Randomization Process
The course registration system performs a randomization process for subjects with limited seats every day at 9:00 am during the Add-or-Drop period.
In the afternoon, you can check the results online. If a course is full and someone drops it, seats may become available.

Tip: Check course enrollment online daily. Alternatively, ask the teacher for permission to enroll through the extra selection process.
How to Verify Your Course Selection
Access the Academic Information System, choose "Select Courses", then "Inquiries Regarding Course Selection Results".
Select the course selection phase: "Add-or-Drop Selection (Log Records & Random Result)" from the drop-down menu.

Understanding the Logs
The upper panel shows the "Course Selection Status" with all verified selections.
The "Course Selection Add/Drop Log Records" section shows detailed logs and randomization results.
Last-Minute Selection
Students may choose restricted courses until the last minute on the final day of Add-or-Drop.
The randomization results will only be available after noon, so course status cannot be changed until then.
End of Add/Drop Period
The course selection process concludes at the end of the Add or Drop period. Before this deadline, you must review your course choices carefully to ensure accuracy, and you may still modify, add, or drop courses. Any courses dropped on or before this date will be removed from your academic record. After the deadline, the system records maintained by the Computer and Communication Center are final, and students are responsible for their own selections without exception.
