What the service is for
Course lists can be difficult to scan when a student needs to compare a department, course title, course code, schedule, instructor, and remaining capacity at once. Inha Sugang organizes those fields into searchable desktop and mobile views.
Students can filter by department or major, search by course title or code, sort by vacancy, show web lectures, and keep browser-local favorites for a shorter comparison list.
A reliable checking routine
- Confirm the academic period. Read the status banner before using results because priority-registration stages have opening and closing times.
- Search narrowly. Use a department, course title, or course code to avoid confusing similarly named sections.
- Compare the full row. Check instructor, credits, classification, meeting time, classroom, evaluation method, notes, and grade allocation—not only the vacancy number.
- Verify before acting. Open the latest official university information before making a registration decision.
Freshness and timing
The service displays its latest update status near the top of the page and normally refreshes course-catalog information on a twenty-minute cycle while the relevant collection schedule is active. That interval describes the service process; it does not guarantee that every official change appears immediately.
A registration stage can close while a previously collected row remains visible. Treat the status banner and timestamp as essential context. When the service says a stage has ended, the information remains useful for reference but should not be interpreted as an active registration opportunity.
What the vacancy number cannot guarantee
Availability can change
Other students and university processes can change availability after the latest collection.
Eligibility still applies
A visible vacancy does not override grade, major, prerequisite, restriction, or registration rules.
Sections need comparison
Courses with similar titles may have different codes, schedules, instructors, notes, or allocations.
The official system wins
If information differs, rely on the latest applicable Inha University registration or catalog page.
Favorites and privacy
Favorites are intended as a convenience on the current browser. They are not a reservation, registration request, or synchronized university account list. Clearing browser storage or changing devices can remove that local selection.
Do not send student credentials, registration passwords, payment information, identity documents, or other sensitive information when reporting a display problem.
Report an incorrect display
Include the course code, course title, academic period, affected field, time observed, and a link or image of the relevant official information when available. This helps distinguish a delayed update from a parsing or presentation error.
