Osaka University grading scale

Every grade Osaka University awards, the points it carries, and whether it counts toward the GPA or earns credit. This is the table the calculator above runs on.

How the Osaka University GPA formula works

Osaka 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 cut off (always rounded down) to 2 decimal places. Points run from 0.0 up to 4.0, 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 4.0 and A is worth 3.7.

What gets left out of the average

W carry no point value at Osaka 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. 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

Osaka Semester and Cumulative GPA are credit-weighted averages of grade points; digits from the third decimal place are truncated. 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 cut off (always rounded down) to 2 decimal places. Every attempt at a repeated course stays in the cumulative average — the earlier grade is not removed.

How Osaka University compares with other Japan universities

Osaka University is the only Japan university covered here using the 4.00 GPA scale for AY2026 and later entrants; the other 9 universities on this site grade on different scales entirely, so their GPA numbers are not comparable with yours. Rounding is not uniform either: Osaka University has its cumulative average cut off (always rounded down) to 2 decimal places, whereas International Christian University, Keio University and 6 others do it differently. Repeated courses are handled differently again at International Christian University, Keio University and 7 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 Japan comparison table for every university covered there side by side.

Worked examples

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

A typical graded semester

A student sitting at 2.88 after 60 completed credits takes 3 courses worth 3 credits each.

Core course3 credits × A+ (4.0 points)
Elective3 credits × A- (3.3 points)
Lab or seminar3 credits × B (2.7 points)

Semester GPA 3.33 · Updated CGPA 2.93

The semester total is 30 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 W

The same student adds a fourth 3-credit course graded W (Withdrawal).

Core course3 credits × A+ (4.0 points)
Elective3 credits × A- (3.3 points)
Lab or seminar3 credits × B (2.7 points)
Withdrawal course3 credits × W (no grade points)

Semester GPA 3.33 · Updated CGPA 2.93

The semester GPA is unchanged at 3.33. W carries no grade points at Osaka University, so the course is removed from both sides of the division. 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+ (4.0 points)
Elective3 credits × A- (3.3 points)
Failed course3 credits × F (0.0 points)

Semester GPA 2.43 · Updated CGPA 2.82

The semester GPA slips from 3.33 to 2.43, and the cumulative average slips from 2.93 to 2.82. 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 2.88 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 Osaka University scale and rounding.

Projected Osaka University CGPA after a 12-credit semester
If every course is	Semester GPA	New CGPA	Movement
A+ (4.0)	4.00	3.06	+0.18 (better)
A (3.7)	3.70	3.01	+0.13 (better)
A- (3.3)	3.30	2.95	+0.07 (better)
B+ (3.0)	3.00	2.90	+0.02 (better)
B (2.7)	2.70	2.85	−0.03 (worse)

Common mistakes when calculating your Osaka University GPA

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

Assuming your GPA rounds up
Osaka University cuts the cumulative average off at 2 decimal places rather than rounding to the nearest. A calculated 3.4989 is recorded as 3.49, not 3.50 — which matters when a scholarship or honours threshold sits on the boundary.
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.
Guessing the plus/minus values
At Osaka University, A+ is worth 4.0 and A is worth 3.7. Those steps differ between universities, so a value copied from another school's chart will quietly skew the whole average.
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.
Expecting a 0-credit course to move the number
Osaka University allows them, but with no credit hours they contribute nothing to either side of the division.

Osaka University GPA — frequently asked questions

What is a passing grade at Osaka University?

C- (1.0 points) is the weakest grade in the Osaka 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 Osaka University?

4.0 on the 4.00 GPA scale for AY2026 and later entrants, which you reach by earning A+ (4.0 points) in every course that counts toward the GPA.

Does Osaka University round GPA up?

The cumulative average is cut off (always rounded down) to 2 decimal places, and the semester average is cut off (always rounded down) to 2 decimal places. Because the cumulative figure is truncated rather than rounded, a result just short of a threshold stays short of it — 3.4999 is recorded as 3.49.

Is this a generic Japan GPA formula?

No. This page is generated from the grading configuration for Osaka University alone — its 9 point values, its floor rounding, and its own rules for pass/fail and repeated courses. Other universities in Japan routinely use different point values or a different scale entirely, so the same grades can produce a different GPA elsewhere.

Which grades are excluded from the Osaka University GPA?

W (Withdrawal) carry no grade points and are left out of the average. None of them earn credit toward the degree either.

What happens to my GPA if I repeat a course?

Every attempt at a repeated course stays in the cumulative average — the earlier grade is not removed.

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 Osaka University?

A+ covers 90–100% and is worth 4.0 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 Osaka University. The grading data on this page was taken from The University of Osaka - Grade Point Average (GPA) 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.

Osaka University has its own official grading system and is not treated as a generic Japan formula.
This config follows the AY2026-and-later grading table. AY2025-and-earlier undergraduate students use the older S/A/B/C/F table and need manual review.
W is excluded from GPA. Non-attendance without withdrawal and academic misconduct are counted as F under the official policy.
Repeated F attempts remain counted according to the official Osaka GPA page.
