Quick take: Popular and required courses fill in seconds. Move step by step — from pre-planning to the add/drop window — to protect the timetable you want.
When registration season arrives, both Korean and international students get nervous. Required major courses have limited seats and high competition, and system load or slow internet can cost you the class you need. Every school runs registration a little differently, so your first move is to monitor the international office and your department announcements.
What to do at each stage
- Pre-planning — Draft a timetable that avoids clashes and lock in required major courses first as top priority.
- Plan B and C — Line up alternate courses in advance so a failed click does not turn into panic on the day.
- D-day prep — Check your internet and browser compatibility (Chrome, Edge) and save your login to save time at the start.
- During registration — Click your #1 course immediately and try alternates the moment it fails.
- Add/drop window — Watch for cancellations and, if a course is full, ask the professor or department for a permission slip.
- After registration — Recheck your timetable and LMS course list to avoid duplicate or already-taken courses.
When the servers get slammed
If the server crashes or logins keep failing, open a different window or browser instead of hammering refresh, then wait briefly before retrying. If the outage drags on, schools often post extra make-up time or reschedule, so keep an eye on the homepage. Some universities also give exchange and international students priority selection, so check whether you qualify.
