Course Registration

Course registration is the standard procedure to determine which courses students will take throughout the semester.
Course registration takes place online during the announced period (usually a week long) prior to the start of a new semester. You should go through the  SNU CRS Website and make out your own timetable in advance. Be aware of the credit limits depending on your conditions. With the commencement of the semester, modification of your schedule is available through the same registration procedure for the first week only. After the modification period, you may choose to withdraw when you wish not to continue taking a course. The courses from which you have withdrawn may be taken again in the future.

Registration period

First year students: February
Current students: The enrollment period for current students is usually 1 month before the beginning of each semester. For Spring semester registration takes place at the end of January and for the Fall semester the end of July.

※ Refer to the Academic Calendar for this year’s specific schedule.

Enrollment Procedures

You must enroll online at Course Catalogue during the specified period.

Modification of the Enrolled Courses

You are allowed to make changes to your selection of courses freely for the first week of a semester — that is, during the modification period. Log on to Course Catalogue to view your enrollment status. When you wish to make changes, repeat the procedures for enrollment. To drop a course, simply click cancel.

※ Remember to check your credit limits allowed for modification at the top of the enrollment webpage. Should you reach the limit, yet need to make more changes, you must visit the Office of Student Affairs of your college or department administration office and file a petition in person.

Course Withdrawal

Should you wish to drop a course after the modification period (the first week of each semester), you must withdraw before one-third of the semester has passed. Attain and fill out a Course Withdrawal Form and hand it into the Office of Student Affairs of your college or department administration office with the instructor's signed approval. There are no limits to the number of courses from which you can withdraw and withdrawn courses are marked ‘W’ on your transcripts.

※ Course withdrawal is possible after one-third of the semester has passed without academic penalties only in extreme circumstances proven with official certificatesn (e.g., medical certificates) and when the final exam has not been taken.

Course Repetition

Course Repetition Restriction

Course Repetition is allowed only for courses in which a student received a grade of C+ or below (as applied since March 2006). Courses taken before 2006 are excluded from this restriction.

Course Repetition Procedures

When enrolling, choose the same course and enter into the designated space the year and semester the course was originally taken.
Ex) If a course was taken during the 2nd semester (Fall) of 2005, enter ‘20052’ into the designated space.

Grading of Repeated Courses

If students repeatedly take the same course, the latter grade replaces the previous grade received. Repeated courses will be marked as ‘R’. The College of Medicine and the College of Veterinary Medicine has different rules for course repetition.

Summer & Winter Sessions

Summer and winter sessions are distinguished from regular semesters in that they are offered to students as a chance to acquire credits during vacations and are open to those who wish to take classes during these sessions.

Course Enrollment

Registration period

Summer session: mid-May
Winter session: mid-November

Credit limits for each session are as follows:

Summer session: 9 credits
Winter session: 6 credits (effective 2008)

Students in the following categories may enroll for these sessions:

Current undergraduate or graduate students (those on Leave of Absence included)
If you wish to enroll for a session in order to graduate right after the session,
you must have been registered for the previous Spring/Fall semester to be eligible to apply for the session.
Students from other schools on academic exchange agreements with recommendations from the Dean
Students of foreign nationality from universitiesabroad with recommendations from the Office of International Affairs

Course Withdrawal

Courses enrolled in during summer & winter sessions cannot be modified, therefore the only choice is to withdraw. The deadline is the halfway point of the session.
Tuition fees already paid will be refunded according to the following timeline.
  • Before the session begins: total amount
  • Before one-third of the session has passed: 2/3 of the total amount
  • After the one-third mark and before the halfway point of the session: 1/2 of the total amount
  • After the halfway point of the session: no refund

Credits and GPA Application Standards

According to the University Regulations, the credits earned during sessions may be included in a student’s total credits in an undergraduate program. However, sessions are not counted as Course Terms and therefore do not affect the limit on Course Terms a student may attend. Grades from sessions do not contribute to the GPA average of individual regular semesters, but is included in the student’s GPA average for the whole year. When you take a course that has been opened as a substitute for paper submission and earn above a certain grade, you may be exempted from that course’s exam.
