How the Pusan National University GPA formula works

Pusan National 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 rounded to the nearest 2 decimal places. Points run from 0.0 up to 4.5, so a higher average is a better result. The scale uses plus and minus grades, so there are 9 distinct point values rather than a handful of whole steps: A+ is worth 4.5 and A0 is worth 4.0.

What gets left out of the average

S, U, P, and PF carry no point value at Pusan National 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. S and P 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

PNU GPA is grade point multiplied by course credits, summed and divided by registered credits, rounded at the third decimal place; S/U courses are excluded. 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 rounded to the nearest 2 decimal places. The most recent attempt replaces the earlier one, so only the newest grade counts toward the cumulative average.

How Pusan National University compares with other South Korea universities

Pusan National University shares the 4.50 GPA scale with Hanyang University, Korea University, and Sungkyunkwan University, while Ewha Womans University, KAIST, POSTECH and 4 others grade on a different scale. Rounding is not uniform either: Pusan National University has its cumulative average rounded to the nearest 2 decimal places, whereas Yonsei University does it differently. Repeated courses are handled differently again at Hanyang University, KAIST and 6 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

Pusan National University does not grade on the US 4.0 scale. Its scale runs to 4.5 rather than 4.0, with 9 point values in use and D0 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 Pusan National 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 Pusan National University's own rounding.

A typical graded semester

A student sitting at 3.24 after 60 completed credits takes 3 courses worth 3 credits each.

  • Core course3 credits × A+ (4.5 points)
  • Elective3 credits × B+ (3.5 points)
  • Lab or seminar3 credits × C+ (2.5 points)

Semester GPA 3.50 · Updated CGPA 3.27

The semester total is 31.5 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 S

The same student adds a fourth 3-credit course graded S (Satisfactory).

  • Core course3 credits × A+ (4.5 points)
  • Elective3 credits × B+ (3.5 points)
  • Lab or seminar3 credits × C+ (2.5 points)
  • Satisfactory course3 credits × S (no grade points)

Semester GPA 3.50 · Updated CGPA 3.27

The semester GPA is unchanged at 3.50. S carries no grade points at Pusan National 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+ (4.5 points)
  • Elective3 credits × B+ (3.5 points)
  • Failed course3 credits × F (0.0 points)

Semester GPA 2.67 · Updated CGPA 3.17

The semester GPA slips from 3.50 to 2.67, and the cumulative average slips from 3.27 to 3.17. 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 3.24 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 Pusan National University scale and rounding.

Common mistakes when calculating your Pusan National University GPA

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

  1. Counting S and P courses in the average

    These earn credit at Pusan National 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.

  2. 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.

  3. Guessing the plus/minus values

    At Pusan National University, A+ is worth 4.5 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.

  4. 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.

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

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

  6. Handling a retake by guesswork

    The most recent attempt replaces the earlier one, so only the newest grade counts toward the cumulative average. Check the current catalog before assuming an old grade has left your record.

Pusan National University GPA — frequently asked questions

What is a passing grade at Pusan National University?

D0 (1.0 points) is the weakest grade in the Pusan National 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 Pusan National University?

4.5 on the 4.50 GPA scale, which you reach by earning A+ (4.5 points) in every course that counts toward the GPA.

Does Pusan National University round GPA up?

The cumulative average is rounded to the nearest 2 decimal places, and the semester average is rounded to the nearest 2 decimal places. That is ordinary rounding, so a result sitting exactly half a step along goes up.

Is this a generic South Korea GPA formula?

No. This page is generated from the grading configuration for Pusan National University alone — its 9 point values, its standard 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. S and P earn credit at Pusan National 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 Pusan National University GPA?

S (Satisfactory), U (Unsatisfactory), P (Pass), and PF (Pass/Fail Course Fail) carry no grade points and are left out of the average. Of those, S and P still earn credit toward the degree.

What happens to my GPA if I repeat a course?

The most recent attempt replaces the earlier one, so only the newest grade counts toward the cumulative average.

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.

What percentage is a A+ at Pusan National University?

A+ covers 95–100% and is worth 4.5 grade points. The full percentage-to-grade table for all 9 graded bands is published on this page.

Is this calculator official?

No. GPAWorld is an independent tool and is not affiliated with or endorsed by Pusan National University. The grading data on this page was taken from Pusan National University Student Support System - Grades and Pusan National University - Lectures and Repeating Courses and last verified on 2026-07-21; every source is linked on this page so you can check it yourself. Your registrar's record is always the authority.

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.

  • PNU has its own official grading system and is not treated as a generic South Korea formula.
  • S/U courses are excluded from GPA according to the official student support page.
  • Pass/fail fail is encoded as PF to avoid conflict with the ordinary zero-point F grade.
  • Retake handling is encoded as latest attempt replaces based on the official repeated-course statement; retake grade caps are not enforced by the calculator.
