2. Eligibility: Students on the Sinchon (International) Campus and Mirae Campus who are enrolled students and students at leave of absence(including leave of absence for military service)

1) Those who are scheduled to graduate in August 2025 can also take seasonal classes, and the credits will be reflected in the graduation situation. However, note that graduation candidates cannot take some subjects, such as community service.

2) Students on leave cannot graduate even if they meet graduation credits in seasonal classes, and they must return for a regular semester to graduate. In other words, students taking the Spring 2025 semester off cannot graduate in August 2025 even if they meet graduation credit requirements in the 2025 summer seasonal classes.

3) Students serving in the military cannot take face-to-face lectures. However, if the discharge date is before the start of the seasonal semester, the student can apply for and take the seasonal classes. In addition, if the student's unreturned discharge date is in the seasonal semester, the Ministry of National Defense may order the student to return to force, and the disadvantage is the student's responsibility.

  ※ According to the Military Manpower Administration’s service regulations, Social Service Agents are prohibited from attending school during their service period.

8. Notes

1) If a student belonging to the University College takes a seasonal class, it is recognized as a completed course, and the acquired grades are also included in the average when approving the major. However, in the case of re-taking a course, only the previous grades before re-taking will be applied for the major approval.

2) Re-taking: since it is only possible to re-take the subjects that the student's final grades are recorded, so re-taking the courses that had been taken in the previous semester is not possible.

3) If the tuition is not paid during the registration period, the entire course registration details will be automatically deleted.

4) The student who has applied for 2 subjects cannot pay only the amount for the 1 subject for the purpose of canceling another subject. You should first pay the tuition for all the enrolled courses, then cancel a subject. Refer to the 7. Canceling Courses above for how to cancel the course.

5) Seasonal classes can only be taken on only one campus among the Sinchon (International) Campus, Mirae Campus, or a credit exchange university. All duplicated applications will be invalidated.
