How the Yonsei University GPA formula works

Yonsei University converts every graded course into quality points by multiplying the grade's point value by the course's credit hours. Your semester GPA is the total quality points divided by the total credit hours that count toward the GPA, and the result is always rounded up to 2 decimal places. Points run from 0.0 up to 4.3, so a higher average is a better result. The scale uses plus and minus grades, so there are 13 distinct point values rather than a handful of whole steps: A+ is worth 4.3 and A0 is worth 4.0.

What gets left out of the average

P, NP, S, U, and W carry no point value at Yonsei University, so a course marked with one of them drops out of the division entirely — it changes neither the top nor the bottom of the fraction. P and S still earn credit toward your degree while staying out of the GPA, which is why your credit total can climb in a semester where your GPA barely moves. F works the other way: it earns no credit but is still counted in the average at 0.0 points, so a failed course pulls the average down while adding nothing to your progress.

How this semester rolls into your CGPA

Yonsei total grade points are grade score multiplied by credit hours, divided by total credit units attempted for letter-graded courses. In practice that means your existing CGPA is turned back into quality points by multiplying it by your completed credits, this semester's quality points are added on, and the total is divided by your new credit total. Both the semester and the cumulative figures are always rounded up to 2 decimal places. Repeat handling is not published as a rule this calculator can apply automatically, so retaken courses need to be checked against the current catalog.

How Yonsei University compares with other South Korea universities

Yonsei University shares the 4.30 GPA scale with Ewha Womans University, KAIST, POSTECH and 3 others, while Hanyang University, Korea University, Pusan National University and 1 other grade on a different scale. Rounding is not uniform either: Yonsei University has its cumulative average always rounded up to 2 decimal places, whereas Ewha Womans University, Hanyang University and 8 others do it differently. Repeated courses are handled differently again at Ewha Womans University, Korea University and 2 others.

A GPA only means something alongside the scale it was calculated on, which is why comparing raw numbers between institutions — even neighbouring ones — is unreliable. See the South Korea comparison table for every university covered there side by side.

Converting this GPA to a 4.0 scale

Yonsei University does not grade on the US 4.0 scale. Its scale runs to 4.3 rather than 4.0, with 13 point values in use and D- as the lowest passing mark. There is no single correct formula for converting that into a 4.0 GPA, and GPAWorld deliberately does not publish one: every graduate school, employer and credential evaluator applies its own conversion table, and a number invented here could cost you an application. Calculate your GPA on this page using the real Yonsei University scale, then let the institution you are applying to convert it with their table.

Worked examples

Each example below is run through the same engine the calculator uses, so the numbers show Yonsei University's own rounding.

A typical graded semester

A student sitting at 3.10 after 60 completed credits takes 3 courses worth 3 credits each.

  • Core course3 credits × A+ (4.3 points)
  • Elective3 credits × A- (3.7 points)
  • Lab or seminar3 credits × B0 (3.0 points)

Semester GPA 3.67 · Updated CGPA 3.18

The semester total is 33 quality points over 9 counted credits. Because the cumulative average now spans 69 credits, one semester moves it only a little — this is why a CGPA gets harder to shift the further into a degree you are.

Adding a course graded P

The same student adds a fourth 3-credit course graded P (Pass).

  • Core course3 credits × A+ (4.3 points)
  • Elective3 credits × A- (3.7 points)
  • Lab or seminar3 credits × B0 (3.0 points)
  • Pass course3 credits × P (no grade points)

Semester GPA 3.67 · Updated CGPA 3.18

The semester GPA is unchanged at 3.67. P carries no grade points at Yonsei University, so the course is removed from both sides of the division — even though the credit still counts toward the degree. Students often expect a fourth course to move the average and are surprised when it does not.

What one F costs

The same semester again, but the last course comes back as F (Fail) instead.

  • Core course3 credits × A+ (4.3 points)
  • Elective3 credits × A- (3.7 points)
  • Failed course3 credits × F (0.0 points)

Semester GPA 2.67 · Updated CGPA 3.05

The semester GPA slips from 3.67 to 2.67, and the cumulative average slips from 3.18 to 3.05. F is worth 0.0 points and earns no credit, so it weighs the average down while adding nothing to your degree progress.

What this semester does to your CGPA

A student with a 3.10 CGPA after 60 credits takes 4 courses worth 3 credits each (12 credits in total). Here is where that CGPA lands if every course comes back at the same grade — calculated with the Yonsei University scale and rounding.

Common mistakes when calculating your Yonsei University GPA

These are the places where the Yonsei University rules differ from what most students assume, and where a hand calculation usually goes wrong.

  1. Rounding down out of caution

    Yonsei University rounds the cumulative average *up* to 2 decimal places, so a hand calculation that rounds the ordinary way comes out slightly low.

  2. Counting P and S courses in the average

    These earn credit at Yonsei University but carry no grade points, so they belong in your credit total and nowhere near the GPA division. Including them is one of the most common reasons a hand-calculated GPA comes out wrong.

  3. Dropping a failed course from the calculation

    F earns no credit toward the degree, but it is still counted in the GPA at 0.0 points. Leaving a failure out flatters the result.

  4. Guessing the plus/minus values

    At Yonsei University, A+ is worth 4.3 and A0 is worth 4.0. Those steps differ between universities, so a value copied from another school's chart will quietly skew the whole average.

  5. Averaging the grades instead of weighting them

    A course worth twice the credits moves your GPA twice as much. Adding up your grade points and dividing by the number of courses ignores that weighting and is almost always wrong.

  6. Expecting a 0-credit course to move the number

    Yonsei University allows them, but with no credit hours they contribute nothing to either side of the division.

  7. Handling a retake by guesswork

    Repeat handling is not published as a rule this calculator can apply automatically, so retaken courses need to be checked against the current catalog. Check the current catalog before assuming an old grade has left your record.

Yonsei University GPA — frequently asked questions

What is a passing grade at Yonsei University?

D- (0.7 points) is the weakest grade in the Yonsei University table that still earns credit. Anything below it — F — is counted in your GPA but earns no credit toward the degree. Individual programmes can set a higher minimum for courses in your major, so check your programme handbook as well.

What is the best GPA you can get at Yonsei University?

4.3 on the 4.30 GPA scale, which you reach by earning A+ (4.3 points) in every course that counts toward the GPA.

Does Yonsei University round GPA up?

The cumulative average is always rounded up to 2 decimal places, and the semester average is always rounded up to 2 decimal places. Because the cumulative figure is rounded up, a hand calculation that rounds the ordinary way comes out slightly low.

Is this a generic South Korea GPA formula?

No. This page is generated from the grading configuration for Yonsei University alone — its 13 point values, its ceil rounding, and its own rules for pass/fail and repeated courses. Other universities in South Korea routinely use different point values or a different scale entirely, so the same grades can produce a different GPA elsewhere.

Do pass/fail courses affect my GPA?

No. P and S earn credit at Yonsei University without carrying grade points, so they are excluded from the GPA division entirely. Your completed-credit total goes up while the average stays where it was.

Which grades are excluded from the Yonsei University GPA?

P (Pass), NP (Non-Pass), S (Satisfactory), U (Unsatisfactory), and W (Withdrawn) carry no grade points and are left out of the average. Of those, P and S still earn credit toward the degree.

What happens to my GPA if I repeat a course?

Repeat handling is not published as a rule this calculator can apply automatically, so retaken courses need to be checked against the current catalog.

How much does one semester change my cumulative GPA?

Your CGPA is weighted by every credit you have already completed, so a single semester moves it less the further along you are. Fifteen credits added to sixty already completed is a fifth of your record; the same fifteen added to a hundred and twenty is an eighth of it. Use the calculator at the top of this page with your real completed-credit total rather than estimating the movement.

Is this calculator official?

No. GPAWorld is an independent tool and is not affiliated with or endorsed by Yonsei University. The grading data on this page was taken from Yonsei University - Grading System and last verified on 2026-07-21; every source is linked on this page so you can check it yourself.

Notes on this university's data

Judgement calls and caveats recorded when this grading configuration was built from the official sources. They are published so you can see exactly what the calculator assumes.

  • Yonsei has its own official grading system and is not treated as a generic South Korea formula.
  • P, NP, S, U, and W are excluded from GPA according to the official grading page.
  • Yonsei states GPA decimals beyond the hundredths are rounded up; this config uses ceiling at two decimals.
  • Repeated-course handling is manual review because a clear public repeat replacement rule was not found.
