Course Requirement

SNU requires all students to complete a specific number of credits for different types of courses including general education courses and major courses as well as specific courses. The requirements vary by department, but students must satisfy their department requirements for graduation. Below is the common requirement for all departments. However, some departments may have different requirements than shown here so make sure to check your department requirements.

General education courses:36 credits or more (based on the lowest requirement)
Major courses:60 credits or more- Major courses when studying double major/minor : 39 credits or more (based on the lowest requirement)
130 credits or more for graduation (based on the lowest requirement)
Tips for each course type
  • Mandatory major : courses offered by the department that are mandatory
  • Elective major : courses offered by the department that are optional
  • General education : courses that can be taken freely and some general education courses of specific fields may be required
  • Teacher training : educational theory and hands-on courses for teaching certification
  • General elective : course classification when taking a major course offered by a department other than the department the student is affiliated to and these credits are not counted in the major or general education course requirements
  • Although the classification of a course can be changed through the corresponding department office, such a change is only possible when the request is approved.

Course Registration

All students are to use the course registration website to register for the next semester courses before the beginning of the semester. Course registration anywhere with Internet access, but make sure to be quick since the maximum number of students for each course can fill up very fast right after course registration begins. Courses with times that overlap cannot be registered and generally a maximum of 18 credits can be registered. However, courses like the freshmen seminar can be registered regardless of such registration restrictions. Students with a GPA of 3.3 or higher for the 2 previous semesters can register up to 21 credits, but since this condition is to assess whether the student was diligent academically for the past 2 semesters, if there were repeated courses in the past 2 semesters, both the original and repeated grades are included in the calculation.

Before the course registration period, there is always the preliminary course registration period. When course registration is done during this period, the registration button can be clicked on faster. Also, you can see how many competitors have registered for a course during the preliminary period so this information can be important in coming up with a strategy on the order of courses to click the registration button.If you could not register a course you wanted to take, you can try at it again by 'Quota exceeding course registration request'. There are 3 steps for this request; request-approval-confirm registration. If you visit SNU CRS (Course Registration System), you can find it under 'couse registration' menu. After you submit requests, an instructor or each course's department office will approve or reject you request. Once you requests is approved, you should confirm course registration in qouta exceeding course registration menu within designated period. Please make sure there is no overlapping courses and you have available credits for course registration before request. 

All freshmen register courses in the same period. Course registration method is combined with adding courses to course cart and first-come-served course registration. Day 1-2 of course registration is shopping period; you can add courses to course cart. On day 3, the office of academic affairs confirms course cart requests into course registration only if cart requests are no more than course quota. If cart requests exceed course quota, courses will be designated as "Pending courses" and no one will be registered. On day 4 (first-come-first-served course registration day 1), course registration of pending courses are restricted to students who had added courses to course carts. On day 5-6 (first-come-first-served course registration day 2-3), all students can register pending courses for remaining quota. Meanwhile, for courses which have not reached their quota, all students can freely register these courses for entire 3 days of first-come-first-served course registration period. If there are vacancies for courses which had reached its quota, "available quota after cancellation" mark will appear. During first-come-first-served course registration period and course change period, available quota after cancellation can be registered only 3 times a day. You can find out detailed time if you press the mark. 

Make sure to be aware of courses of certain departments and colleges that restrict course registration and read up on the details of courses since some are taught only in English while some are held in a different campus. Note that the year number displayed in the course information is only the recommended year and it does not limit students of other years from registering. Make sure to check the course syllabus and information as well as whether the course can be registered through the pop-up window when clicking the course title or the remarks column in the course search of the course registration website.

When there is no movement for 10 minutes in the course registration website, you are automatically signed out and abnormal course registration attempts will result in being blocked out for 30 minutes. Since the spring semester of 2012, additional security measures were added to prevent the use of illegal programs. Now you have to input the security text shown before clicking the course registration button and 5 input errors will sign you out automatically.

Academic Disenrollment (Probation)

Students with grades below a certain level can be disenrolled (Removal of the student name from the register). Students with GPAs lower than 1.7 or F grades for more than 3 courses or 6 credits are placed under academic probation. Undergraduate students who are placed under academic probation 4 times are subject to disenrollment. To prevent this, the university identifies students who were placed under academic probation 2~3 times and their departments are notified.

Semester Classification

SNU’s academic calendar consists of 1st semester (Spring) and 2nd semester (Fall). Each semester then comprises a regular semester (16 weeks) and an extra session (5 weeks), followed by summer/winter vacation.

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

  • Course Resistration Period: Summer - mid May / Winter - mid November
  • Credit Limits: Students are allowed to take maximum 9 credits in summer and 6 credits in winter semester.

Course Change/Override

During the course change/override period, the course registration website will be open again to all students and you will be able to register for the courses that have remaining seats.

Note: For course registration, students must login with their student number (2021-8****) and its own password. The system opens from 9 am to 6 pm.

If the course you want to add is already full or restricted online, upon a confirmation from the instructor, you may get an additional seat for the course. This manual course registration is called course override. To file a course override form, you must e-mail the instructor to inquire on the course override availability. Please note that not every instructor will be able to accommodate your request. In this case, you must find another course.

How to?


Check your current list of registered courses through mySNU or course registration website.

  • mySNU > Academic Affairs > Class/Grade > Class > My Courses or My Timetable
  • Course registration website > Course Registration (green menu) > Details of Course Registration; if you wish to drop a course, you can delete it from this menu.
If you wish to add more courses, register for the course through Course Search in the same way you did for the previous online course registration. The newly added course will appear on your eTL on the next day.
What if the course you wished to take is full already? Or, what if the course is restricted and you cannot access it? For the courses with full quota, please check the course registration website as frequently as possible to find an available seat, as there usually are lots of changes made in registration status during the course change period. If you cannot ever access the course due to the restriction, you may ask the instructor to allow you to take the course and this process for acquiring a permission for additional registration is called as course override and “CHO-AN-JI (초안지) ” in SNU’s notion.


Since the course override procedure may vary by department, please check the website of the department office that opens the course. The college and department information for each course can be found in the following way:



Fill out the override form. You can find the required information from the course registration website; see Ac (ademic). Y (ea) r., Course No., Lec (ture). No., Course Title and the first number of Cred (it).-Lec (ture hour per week).-Lab (hour per week).
Contact the instructor to ask for a permission. You can find the instructor’s contact information when you click on the course title. In the e-mail, introduce yourself and state why you need this course, submitting the filled out override form.
In case your request is approved, the instructor will inform you what to do next (how to submit the form to the department office) and when you complete the form submission procedure, the course will be added on your mySNU and eTL the next day.In many cases, the instructor will ask you to send the override form and the instructors’ approval e-mail to the department office that opens the course. For example, if the course is open by Dept. of Mechanical and Aerospace Engineering, you must submit the form to the Mechanical and Aerospace Engineering departmental office, even though you are affiliated with a different department.
If the course to be overriden clashes with any existing course in your timetable, you must delete the existing one on the course registration system to empty the slot for the newly added course, by the last day of the course change period (September 14, 6 pm). Also, the total number of courses must be 18 credits or less, so you must ensure the total of the final number of credits do not exceed 18 credits.
