Every grade Waseda 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.
| Grade | Meaning | Mark range | Points | GPA counted | Credit earned |
|---|---|---|---|---|---|
| A+ | A+ | 90–100% | 4.0 | Yes | Yes |
| A | A | 80–89.999% | 3.0 | Yes | Yes |
| B | B | 70–79.999% | 2.0 | Yes | Yes |
| C | C | 60–69.999% | 1.0 | Yes | Yes |
| F | Fail | — | 0.0 | Yes | No |
| G | Fail | — | 0.0 | Yes | No |
| P | Pass | — | Excluded | No | Yes |
| N | Accreditation | — | Excluded | No | Yes |
| Q | Not Shown/Not Completed | — | Excluded | No | No |
Waseda 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 4.0, so a higher average is a better result. The scale uses plus and minus grades, so there are 6 distinct point values rather than a handful of whole steps: A+ is worth 4.0 and A is worth 3.0.
P, N, and Q carry no point value at Waseda 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 N 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 and G work the other way: they earn no credit but are still counted in the average at 0.0 points, so a failed course pulls the average down while adding nothing to your progress.
Waseda GPA is the sum of course credits multiplied by Grade Points, divided by total registered credits for graduation-counting courses; failed credits are included. 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. Repeat handling is not published as a rule this calculator can apply automatically, so retaken courses need to be checked against the current catalog.
Waseda University shares the 4.00 GPA scale with International Christian University, Keio University, Kyushu University and 2 others, while Kyoto University, Nagoya University, Osaka University and 1 other grade on a different scale. Rounding is not uniform either: Waseda University has its cumulative average rounded to the nearest 2 decimal places, whereas Osaka University and Tohoku University do it differently. Repeated courses are handled differently again at Osaka University.
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.
Each example below is run through the same engine the calculator uses, so the numbers show Waseda University's own rounding.
A student sitting at 2.88 after 60 completed credits takes 3 courses worth 3 credits each.
Semester GPA 2.00 · Updated CGPA 2.77
The semester total is 18 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.
The same student adds a fourth 3-credit course graded P (Pass).
Semester GPA 2.00 · Updated CGPA 2.77
The semester GPA is unchanged at 2.00. P carries no grade points at Waseda 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.
The same semester again, but the last course comes back as F (Fail) instead.
Semester GPA 2.00 · Updated CGPA 2.77
The semester GPA stays at 2.00, and the cumulative average stays at 2.77. F is worth 0.0 points and earns no credit, so it weighs the average down while adding nothing to your degree progress.
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 Waseda University scale and rounding.
| If every course is | Semester GPA | New CGPA | Movement |
|---|---|---|---|
| A+ (4.0) | 4.00 | 3.07 | +0.19 (better) |
| A (3.0) | 3.00 | 2.90 | +0.02 (better) |
| B (2.0) | 2.00 | 2.73 | −0.15 (worse) |
| C (1.0) | 1.00 | 2.57 | −0.31 (worse) |
| F (0.0) | 0.00 | 2.40 | −0.48 (worse) |

These are the places where the Waseda University rules differ from what most students assume, and where a hand calculation usually goes wrong.
Counting P and N courses in the average
These earn credit at Waseda 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.
Dropping a failed course from the calculation
F and G earn no credit toward the degree, but they are still counted in the GPA at 0.0 points. Leaving a failure out flatters the result.
Guessing the plus/minus values
At Waseda University, A+ is worth 4.0 and A is worth 3.0. 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
Waseda University allows them, but with no credit hours they contribute nothing to either side of the division.
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.
C (1.0 points) is the weakest grade in the Waseda University table that still earns credit. Anything below it — F and G — 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.
4.0 on the 4.00 GPA scale, which you reach by earning A+ (4.0 points) in every course that counts toward the GPA.
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.
No. This page is generated from the grading configuration for Waseda University alone — its 6 point values, its standard 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.
No. P and N earn credit at Waseda 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.
P (Pass), N (Accreditation), and Q (Not Shown/Not Completed) carry no grade points and are left out of the average. Of those, P and N still earn credit toward the degree.
Repeat handling is not published as a rule this calculator can apply automatically, so retaken courses need to be checked against the current catalog.
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.
A+ covers 90–100% and is worth 4.0 grade points. The full percentage-to-grade table for all 4 graded bands is published on this page.
