Korean universities commonly use letter grades and GPA, but there is no single GPA scale used by every institution. Some universities use a 4.3 scale while others use 4.5, and courses may be graded through relative evaluation, absolute evaluation, or pass/fail systems. International students should understand their own university’s grading rules because GPA can affect scholarships, academic standing, exchange opportunities, and graduation.
If you are starting university in Korea, understanding the grading system should be one of your first academic priorities.
Korean universities commonly use letter grades such as A, B, C, D, and F together with a grade point average, or GPA.
However, there is no single GPA scale used by every Korean university.
Some universities use a 4.3 scale, while others use a 4.5 scale. Evaluation methods can also differ by university, department, and course.
ㅤ
There Is No Single Korean University GPA Scale
One of the most important things for international students to understand is that Korean university GPA systems are not completely standardized.
Seoul National University currently uses a 4.3-point scale, with A+ worth 4.3, A0 worth 4.0, and F worth 0. Yonsei University also uses a 4.3 scale.
Korea University publishes a 4.5-point grading system in which A+ is worth 4.5, A is 4.0, B+ is 3.5, and F is 0.
This means a GPA such as 4.0 has a different meaning depending on whether your university uses a 4.3 or 4.5 maximum.
ㅤ
Typical Letter Grades
A common grading structure uses grades from A through F.
An A represents strong academic performance, while B and C indicate progressively lower performance. D may still represent a passing grade under some university rules, while F normally means the course was failed.
The exact grade points differ according to the university’s scale.
Always check the official academic regulations rather than assuming that the grading table used by another Korean university also applies to you.
ㅤ
What Does A0 Mean?
International students may notice grades such as A0 or B0 at universities using a 4.3 scale.
In this notation, A0 means the standard A grade between A+ and A-. For example, at Seoul National University and Yonsei University, A+ is 4.3, A0 is 4.0, and A- is 3.7.
The zero is part of the Korean grading notation. It does not mean that the student received zero points.
ㅤ
Some Universities Use 4.5 Instead
Other institutions use a 4.5-point scale.
For example, Korea University publishes a grading table with A+ at 4.5, A at 4.0, B+ at 3.5, B at 3.0, and so on.
When applying for scholarships, graduate schools, internships, or jobs, make sure you state both your GPA and the maximum scale.
Writing only ‘GPA 4.0’ can be misleading. A clearer format is ‘4.0/4.3’ or ‘4.0/4.5.’
ㅤ
How GPA Is Calculated
Your GPA is normally calculated using the grade points you receive and the number of credits assigned to each course.
A three-credit course generally affects your GPA more than a one-credit course because it carries more academic weight.
Courses evaluated only as pass/fail or satisfactory/unsatisfactory may be excluded from the numerical GPA calculation, depending on university rules.
Your transcript will show the grading system used by your institution.
ㅤ
Relative Grading vs Absolute Grading
Korean university courses may use relative grading, absolute grading, pass/fail evaluation, or another method established by the institution.
Under relative grading, your result can depend partly on your performance compared with other students in the class. The university may limit the proportion of students receiving particular grade groups.
Under absolute grading, the professor evaluates students against defined performance standards rather than a required class distribution.
Yonsei University, for example, currently publishes separate rules for relative evaluation, absolute evaluation, and P/NP courses. The applicable method depends on the course and university rules.
ㅤ
Do Not Assume Every Class Is Graded on a Curve
International students sometimes hear that all Korean university courses use strict curves.
That is too simple.
Grading methods vary. Small classes, certain English-language courses, practical courses, seminars, laboratory classes, and other designated subjects may follow different evaluation policies.
Your course syllabus is usually the best place to check how an individual class will be evaluated.
ㅤ
Your Syllabus Tells You How the Grade Is Built
During the first week of the semester, read every syllabus carefully.
A final grade may be based on a combination of attendance, participation, quizzes, assignments, presentations, midterm examinations, final examinations, and group projects.
Two courses at the same university can use completely different grading structures.
Knowing the percentages early allows you to decide where your effort will have the greatest impact.
ㅤ
Attendance Can Affect Your Grade
Attendance is often an important part of Korean university courses.
Some professors directly include attendance in the final grade. University regulations may also set limits on how much class a student can miss before losing academic credit.
For example, Yonsei University’s current academic regulations state that a course grade is not recognized when a student is absent for at least one-third of the actual class period, subject to its rules on recognized absences.
Your own university may use different thresholds, so check its regulations and each course syllabus.
ㅤ
What Is Pass/Fail?
Some courses are not assigned a normal letter grade.
They may instead use labels such as P/NP, meaning Pass or Non-Pass, or S/U, meaning Satisfactory or Unsatisfactory.
Seoul National University states that designated S/U courses are excluded from GPA calculation, and Yonsei also lists P/NP categories for certain courses.
These courses can still be required for graduation even when they do not increase or decrease your numerical GPA.
ㅤ
What Happens If You Get an F?
An F normally means you failed the course and did not earn the expected credit.
The F may also affect your GPA according to university regulations.
If the course is required for your major or graduation, you may need to take it again.
Do not wait until your final year to discover that a failed required course is offered only once each year.
ㅤ
Can You Retake a Course?
Many Korean universities allow students to retake certain courses, but the rules are university-specific.
There may be restrictions on which grades qualify for a retake and on the maximum grade that can be received after retaking the course.
Korea University, for example, currently publishes rules allowing retakes for courses with C+ or below under the relevant policy, with limits on the grade obtainable after retaking.
Check your own university’s current retake policy before registering again.
ㅤ
Why GPA Matters for International Students
Your GPA affects more than your transcript.
It can influence scholarship renewal, academic probation, exchange applications, double-major or program applications, graduate school admission, internships, and some employment applications.
For international students receiving tuition scholarships, maintaining the required GPA can be particularly important because losing a scholarship may significantly change the cost of the next semester.
ㅤ
Check Your Scholarship GPA Requirement
If you received an international student scholarship, find the renewal conditions during your first semester.
A scholarship may require a minimum semester GPA or cumulative GPA. Some programs also require a minimum number of completed credits or other academic conditions.
Do not assume that receiving a scholarship at admission means the same tuition reduction automatically continues for four years.
Know the required GPA before the first midterm examination period begins.
ㅤ
Semester GPA vs Cumulative GPA
Your semester GPA measures your performance during one semester.
Your cumulative GPA combines the results included in your academic record across multiple semesters according to university rules.
A weak first semester can therefore continue to affect your cumulative GPA later, although stronger future semesters can improve the overall average.
When reading scholarship or academic rules, check whether they refer to semester GPA or cumulative GPA.
ㅤ
Do Not Compare GPAs Without the Scale
A 4.1 GPA at one Korean university cannot automatically be compared directly with a 4.1 at another institution if the maximum scales are different.
The same issue appears when comparing Korean GPA with a 4.0 system used in another country.
If an external organization asks for a converted GPA, follow its official conversion instructions rather than creating your own formula unless instructed to do so.
Your official transcript should remain the primary record of your academic performance.
ㅤ
How to Protect Your GPA in the First Semester
The best strategy is not to obsess over the number every day.
Instead, build academic habits that make strong grades more likely.
Read the syllabus, attend class consistently, record deadlines, begin major assignments early, review weekly, participate in group work, and ask questions before you fall far behind.
Your first semester is also when you learn how professors at your university design exams and assignments.
ㅤ
A Simple Grading Checklist
At the beginning of every semester, check:
GPA scale / grading method / attendance rule / midterm percentage / final exam percentage / assignments / presentations / group projects / pass-fail status / retake rules / scholarship GPA requirement
This takes only a few minutes per course but can prevent major misunderstandings later.
